The main purpose of UV aging test for vehicle rubber materials is to evaluate their weather resistance and performance stability to determine their service life and performance performance in outdoor environments. Ultraviolet aging test can simulate the influence of ultraviolet radiation in sunlight on vehicle rubber materials. It can work in the following ways:

내후성 평가: Vehicle rubber materials are often exposed to outdoor environments during vehicle use and are affected by factors such as UV rays, 온도 변화, 습기, 대기화학물질. Uv aging tests can simulate these factors to evaluate the weatherability of rubber materials under actual use conditions, including aging resistance, crack resistance and hardening resistance.

Evaluate performance stability: UV radiation can adversely affect the chemical composition and physical properties of vehicle rubber materials, such as hardness changes, reduced elasticity, cracks and deformation. UV 노화 테스트를 통해, the performance stability of rubber materials can be evaluated to know whether their performance degradation, 장기간 사용하면 손상이나 고장이 발생합니다..

Guide material selection and formulation optimization: UV 노화 테스트 결과를 통해, the performance changes of vehicle rubber materials under UV radiation can be understood, so as to guide the selection, formulation optimization and improvement of rubber materials to improve their weather resistance and performance stability.

Specific application
The following are some specific application cases of UV aging test for vehicle rubber materials:

Tires: UV aging tests are performed on the rubber materials of vehicle tires to evaluate their weather resistance, elastic recovery and crack resistance. This helps to determine the service life and performance stability of tires, ensuring their reliability and safety in different climatic conditions.

Seals and O-rings: The rubber materials of vehicle seals and O-rings were subjected to UV aging tests to evaluate their weather resistance and sealing properties. This helps ensure that the seals and O-rings retain their elasticity, tightness, and water resistance over long periods of use.

Rubber seal: UV aging test is conducted on vehicle rubber seal to evaluate its weather resistance and anti-aging performance. This helps to ensure that the rubber seal can effectively prevent the penetration of water, dust and noise in a variety of climatic conditions, maintaining the sealing effect.

Rubber pipelines: UV aging tests are performed on the rubber pipelines of vehicles to evaluate their weather resistance, corrosion resistance and anti-aging properties. This helps to ensure that rubber pipes can maintain their elasticity, tensile resistance and durability under different environmental conditions, avoiding leaks and failures.
