When buying new accessories for the interior of the car, most drivers pay attention to the appearance and price, often ignoring the composition of the product. However, it is the chemical formula that determines how long the floor protection will last, whether it will emit an unpleasant odor and how it will behave in a severe frost or scorching heat. The question of what is the name of the material for EVA matsIt arises in those who want to understand the advantages of this product over classic rubber or pile analogues.
At the heart of these popular car accessories is ethylene vinyl acetate (EVA) is a modern copolymer of ethylene and vinyl acetate. It is not just a “resin” but a high-tech porous material that has a unique shape memory and exceptional elasticity even at extremely low temperatures. Understanding the nature of this substance will help you not to overpay for brands and choose really high-quality products that will not crack after a year of operation.
Next, we will discuss in detail the chemical composition, production nuances and practical properties of this material, so that you can make a balanced choice for your car.
Chemical composition and origin of ethylene vinyl acetate
The material from which modern 3D mats are made is a thermoplastic polymer. ethylene vinyl acetate obtained by copolymerizing ethylene with high-pressure vinyl acetate. The key parameter that affects the final properties of the product is the percentage of vinyl acetate. It depends on this indicator whether the material will be hard and hard or soft and elastic, resembling rubber.
In the production of car mats, a modification with a high content of vinyl acetate is used, which gives the product a characteristic porous structure. This structure is formed in the process of foaming, when special pores are added to the mass. The result is that cellularity, which does not absorb moisture, unlike sponge or foam, but keeps it in special cells until cleaning.
⚠️ Caution: Cheap analogues can be made from secondary raw materials with the addition of large amounts of chalk or talc to reduce the cost. Such material quickly loses elasticity and can have a sharp chemical smell that does not weather for months.
It is important to note that EVA It is an environmentally friendly material if it is produced in compliance with technological standards. It does not contain phthalates, chlorine, and heavy metals, which are often found in cheap technical rubber. This makes the mats safe to use in a confined space of the car, where the air temperature can rise significantly under the influence of sunlight.
The production process also affects quality. Pressure casting allows you to create products with an accuracy of up to a millimeter, repeating the terrain of the floor of a particular car. Unlike stamped rubber, ethylene vinyl acetate It does not require vulcanization, which simplifies the production cycle and reduces the risk of defection.
Smell the mat when buying: A quality EVA has a neutral smell or a slight aroma of plastic, but should not smell of burnt rubber or chemicals.
Physical and mechanical properties and advantages
Why are motorists massively switching to mats from EVA? The answer lies in a unique combination of physical properties that are hard to find in other materials. First of all, it is temperature stability. The material retains its flexibility and elasticity over a wide range of temperatures, from -60°C to +80°C. This means that in winter the carpet will not turn into a “stone” that cannot be straightened, and in summer it will not become sticky and will not begin to deform.
Another important property is wear-resistant. Due to its porous but strong structure, the material perfectly resists mechanical influences. It does not tear from heels, withstands active trampling with legs and does not wear out in places of greatest contact with the sole of the shoe. The service life of quality mats from ethylene vinyl acetate This is 5-7 years of active operation.
- 💧 Moisture protection: The mesh structure retains up to 1-1.5 liters of melt water, preventing it from spreading along the floor of the cabin.
- 🛡️ Chemical inertia: The material does not react to road reagents, oils, gasoline and acid precipitation.
- 🧼 Ease of care: Mud does not eat into the structure, just rinse the mat with water from the hose.
- 🎯 Anti-slip: The back side often has special spikes or texture to prevent the rug from moving.
It is worth mentioning the weight of the product separately. Mats from EVA It is much easier than rubber analogues. This is not only convenient when removing them for cleaning, but also reduces the total weight of the car, which, although insignificant, affects fuel consumption. The lightness of the material is also due to its foamed structure, where a significant part of the volume is occupied by air.
The main advantage of EVA is the combination of the softness of rubber and the strength of plastic, which makes it versatile for any climatic zones.
Comparison with rubber and pile analogues
To understand what the material is for EVA matsIt is necessary to compare it with competitors. The main competitors in the market are classic rubber and textiles (powder). Rubber mats, especially stamped ones, are often made from a mixture of natural and synthetic rubber with the addition of soot and sulfur. They are heavy, can have an unpleasant smell and in the cold bluff, losing the ability to fit the floor relief.
Textile mats, including the popular 3D carpets made of polypropylene, perfectly absorb moisture, but require careful drying. If you spill coffee or bring a lot of snow porridge, the textiles will have to be dried for a long time, otherwise there will be mold and a musty smell in the cabin. ethylene vinyl acetate In this respect, it wins: it does not absorb water, but keeps it in cells.
| Characteristics | EVA (Ethylene vinyl acetate) | Rubber (stamped) | Textiles (swig) |
|---|---|---|---|
| Temperature regime | -60°C ... +80°C | -30°C. +60°C (blubbering) | -20°C ... +50°C |
| Moisture absorption | 0% (holds in cells) | 0% (flows in overflow) | High (absorbing) |
| Weight of kit | Light (2-3 kg) | Heavy (5-7 kg) | Medium (3-4 kg) |
| Term of service | 5-7 years | 2-3 years | 1-2 years |
It's also worth noting the aesthetics. EVA It allows you to create products with any surface texture that mimics honeycombs, diamonds or carbon fiber. Rubber is more likely to have a smooth or simple corrugated surface that quickly rubs with the feet. Textiles, despite their beauty, quickly lose their appearance and are covered with reels.
How to distinguish a quality EVA from a fake
The popularity of the material has given rise to many fakes. Unscrupulous manufacturers can mix ethylene vinyl acetate with cheap fillers or use recycled plastic of poor quality. How can a customer tell the difference between good and bad material without a chemical lab at hand?
The first and most reliable sign is the tactile sensation and smell. Quality EVA It feels nice, slightly velvety, but not sticky. If you run your finger on the surface, there should be no greasy marks. The smell should be minimal. If the mat smells a lot of “chemistry” or old rubber, it is a sign of a technology violation or the use of cheap raw materials.
The second criterion is elasticity. Try to bend the corner of the mat. Good material will easily doubt and immediately straighten out, returning the original form. If a white hall or crack remains at the site of the fold, then there is an overabundance of solid fillers in the material, and such a mat will quickly collapse.
⚠️ Warning: Avoid buying rugs that are sold in a tightly twisted roll without packaging. Prolonged stay in a twisted state can deform the material, and it will not be able to spread in the cabin of the car.
Pay attention to the color. ethylene vinyl acetate The pigment holds well, but the color should be uniform throughout the thickness of the cell. If you see that inside the cells the material is of a different shade or there are white spots, this indicates poor mixing of components during production.
The myth of the "food" EVA
Some sellers claim that their mats are made from "food" EVA, like baby puzzle mats. It's a marketing ploy. While the material is safe, the standards for automotive chemistry and children’s products vary. The main thing is the absence of toxins, not food use.
Rules of care and operation of rugs from EVA
Despite its high strength, the material for EVA mats It requires proper care to maintain its properties throughout its lifetime. The main task is to prevent dirt and reagents from drying up in the cells dead. Regular cleaning takes no more than 5 minutes, but significantly prolongs the life of accessories.
In winter, when there is a lot of salt and sand-salt mixture on the roads, it is recommended to shake out the mats every 2-3 days. Salt is both an aggressive abrasive and a chemical at the same time. If it lies in the cells for a long time, then when pressed, it can damage the walls of the cells, although ethylene vinyl acetate and resistant to chemistry.
For washing, it is best to use ordinary water and a brush with medium stiffness of bristles. Do not use aggressive solvents, acetone or gasoline to remove stains – this can damage the structure of the polymer and make its surface sticky.
- 🚿 Wash: Use a hose with good pressure to knock dirt out of the depths of the cells.
- 🌡️ Drying: Dry the mats in the straightened state, away from open fires and heating appliances.
- 🧽 Persistent spots: Use a weak soap solution and sponge, avoiding abrasive powders.
☑️ Proper EVA carpet washing
In the summer, it is important not to overheat the mats. Although the material is heat resistant, prolonged parking in direct sunlight with closed windows can lead to cabin heating up to 80-90 degrees. In such circumstances EVA It can become too soft and under the weight of heavy objects (for example, canisters with oil) deform. Try to park in the shade or open the windows.
Frequently Asked Questions (FAQ)
Is it true that EVA mats decompose and harm the environment?
No, that's not exactly true. ethylene vinyl acetate It is a polymer, and in the natural environment it decomposes for a very long time, like any plastic. However, unlike PVC (polyvinyl chloride), it does not release chlorine and dioxins when burned or decomposed. It is considered a more environmentally friendly analogue of rubber, but it should be disposed of along with plastic waste, rather than thrown away in the forest.
Can I cut EVA mats if they don't fit in size?
Technically, material. EVA It is easily cut with a regular stationery knife or scissors. However, this is not recommended if the mat is not intended for trimming. Violation of the integrity of the sides will lead to the fact that water will begin to pour out on the floor of the cabin. In addition, the cut edge may look unaesthetic and eventually begin to rag.
Why are new mats sliding on the floor?
New mats from ethylene vinyl acetate They can slide if the back side is smooth or if the floor in the car is dusty. Most models have anti-slip spines. If they are not enough, you can buy special fixers or double-sided tape for carpets. Over time, when the spikes are a little tucked away, the slip will decrease.
What is the difference between EVA and polyurethane?
It's different materials. Polyurethane (often used in high-sided 3D mats) is tougher, heavier and often more expensive. It is better in shape of high sides, but less elastic in the cold. EVA It is softer, lighter and cheaper, better suited for a mesh structure, but high sides of it are rarely made, since they can "play".
How long does the EVA mat dry after washing?
Due to the fact that the material does not absorb water, but only keeps it on the surface of the cells, it dries very quickly. At room temperature or in the wind, 15-30 minutes is enough to make the carpet completely dry. To speed up the process, you can wipe it with rags or use compressed air on the sink.
