Silicone frame for number: selection and installation

Protection of the state registration plate (SRP) is not just an aesthetic decision, but a necessity for every vehicle owner. Harsh climatic conditions, road chemicals, gravel and temperature changes destroy the surface of metal and paint much faster than it seems.

In recent years silicone frame for number has become one of the most popular accessories among car enthusiasts, displacing traditional plastic and metal counterparts. This material has unique physical properties that allow it to remain elastic even in severe frost, which is critically important for the Russian climate.

However, simply choosing a product in the nearest store can lead to problems with traffic police inspectors or rapid failure of the accessory. In this article, we will look in detail at why you should pay attention to high-quality silicone, how to distinguish it from cheap rubber, and what legal requirements must be observed during installation.

Advantages of silicone over plastic and metal

The main reason why drivers switch to silicone frames, lies in their ability to adapt to environmental temperatures. Ordinary plastic, especially low quality, becomes brittle in the cold, like glass, and bursts at the slightest shock or vibration.

In contrast, special automotive silicone retains its flexibility at extremely low temperatures. This allows the frame to absorb the impacts of small stones flying from under the wheels of cars in front without losing its integrity.

Metal frames, popular in the past, have another significant drawback - they are susceptible to corrosion. Even if there is a coating, rust will sooner or later appear at the joints or damage, which can spread to the license plate itself.

Silicone is absolutely inert to water, salt and acids. High-quality silicone does not crack in cold temperatures down to -60 degrees, which makes it an ideal material for the northern regions of the country.

• 🚗 High elasticity of the material prevents breakdowns due to mechanical impact.
• ❄️ Maintains properties at extremely low temperatures without losing shape.
• 🛡️ Full resistance to aggressive chemicals, salt and road reagents.

It is also worth noting the tactile properties and appearance. Silicone is more pleasant to the touch, does not have a strong odor (unlike cheap rubber) and retains its rich color longer, since the pigment is often added to the mass of the material rather than applied on top.

Legal requirements and GOST

When installing any decorative element on a license plate, the driver must remember the traffic rules and technical regulations. The main document regulating this issue is GOST R 50577-2018.

According to the law, the license plate must be legible and must not have any foreign objects that obscure the symbols or limit the view. Silicone frame itself is not prohibited, but it must not overlap any letters or numbers.

⚠️ Attention: If the frame covers even part of the symbol, overlaps the Russian flag or the name of the region, the inspector has every right to issue a fine under Article 12.2 of the Code of Administrative Offenses of the Russian Federation.

Particular attention should be paid to illuminated frames. Any light sources that change color or brightness, as well as flashing elements, are strictly prohibited. They can be regarded as an attempt to hide the number or simulate special signals.

It is also important to consider the thickness of the product. A frame that is too massive can create a shadow on the numbers at certain times of the day, which is also a violation of the requirements for the readability of the sign.

How to distinguish high-quality silicone from a fake

The car accessories market is full of products that sellers call silicone, although in fact it is ordinary rubber or plastic with the addition of softeners. It can be difficult to distinguish them visually, but there are several proven methods.

The first thing you need to pay attention to is the smell. Natural automotive silicone has virtually no odor. If a product emits a sharp, chemical aroma of “burnt rubber,” it is better to refrain from purchasing: such material will quickly lose its elasticity.

The second test is tensile testing. Try to gently stretch the edge of the frame. Cheap material may turn white or crack if subjected to strong tension. High quality silicone uniformly changes shape and returns to its original state without traces of deformation.

The third sign is the surface. It should be matte or slightly rough, but not sticky. Stickiness indicates a violation of production technology and the use of cheap oils that will stain the car body.

Instructions for correct installation

Incorrect installation can negate all the protective properties of the accessory and even lead to damage to the license plate. The installation process is simple, but requires accuracy and adherence to the sequence of actions.

Before starting work, you must thoroughly clean the surface of the license plate and the car body around it. Dirt, sand, or old glue residue may prevent the frame from sealing tightly.

Next, you should carefully insert the license plate into the frame. It is important to do this evenly, starting from one of the long sides, so as not to bend or break the corners of the product, even if it is silicone.

When attaching to the body, use only those holes that are provided by the vehicle design. Do not drill new holes in the bumper or trunk lid.

When tightening the bolts, do not use excessive force. Silicone is a soft material, and an overtightened bolt can push through it, causing the frame to wobble or become deformed.

Comparison of frame types: characteristics table

To finally make a choice, let's compare the main characteristics of various materials used to produce frames for numbers. This will help you weigh the pros and cons.

As can be seen from the table, silicone frame wins in terms of the totality of consumer properties, especially in harsh climates. Metal looks solid, but requires maintenance, and plastic is too fragile for our roads.

Rubber products are a budget option that is often confused with silicone. They quickly fade in the sun, lose their shape and begin to crumble after one season of use.

Care and maintenance in winter

Although silicone does not require complex care, certain operating rules will help extend the life of not only the frame, but also the license plate itself. In winter, a huge amount of reagents are used on the roads.

Whenever you wash your car, pay attention to the inside of the frame. Dirt and salt can accumulate there, which, despite the protection of silicone, can theoretically contribute to the oxidation of the metal plate at the contact points.

⚠️ Attention: Do not use aggressive solvents (acetone, gasoline) to clean the silicone frame. They can destroy the structure of the material and make it sticky.

If you notice that the frame begins to move away from the body or become loose, do not ignore it. Vibration at high speeds can cause the paint on the car to rub off or the license plate itself to break.

To add shine and additional protection, you can use special polishes for plastic and rubber. This will restore the rich black color and create a water-repellent layer.
