1. What are the basic performance of Toyota Car seals?
The basic properties of Toyota Car rubber sealing strips include controllable sealing performance requirements such as hardness performance, tensile performance, strength performance, elongation at break and compression permanent deformation. According to industry standards, Toyota Car seal manufacturers must provide supply status data and hot air aging data on these properties. According to the usage conditions, the hot air aging test temperature is generally selected to be 70°C.
2. What are the properties of ozone aging resistance and atmospheric aging resistance?
Petrol Car are in all-weather conditions for a long time, so the rubber seals of Petrol Car are required to have good ozone aging resistance and atmospheric aging resistance.
1. Ozone aging resistance: Ozone aging is a technology that uses environmental simulation to accelerate the aging process of rubber by ozone based on the characteristic that rubber is sensitive to ozone, thereby testing the aging resistance of rubber products.
2. The performance of hot air aging materials changes with time under the action of hot air.
3. Natural aging: various changes caused by long-term exposure of polymer materials to outdoor conditions, also known as atmospheric aging.
3. What is the paint resistance?
The rubber seals of Petrol Car are installed directly on the car body and are in direct contact with the paint plate of the Toyota Car body. The free substances in the paint of Petrol Car will interact with the rubber seals, thereby accelerating the aging of the rubber seals, so they are resistant to Paint performance is one of the general properties of sealing materials.
4. What are the standards for the low-temperature performance of seals?
The operating temperature of Toyota Car seals is generally -40°C to 70°C, so they are required to have good low-temperature resistance. The brittleness temperature index of the sealing material of the sealing strip.
