Phenyl vinyl silicone rubber is a commonly used silicone material with excellent high temperature resistance, chemical corrosion resistance, weather resistance and other properties, so it is widely used in various extreme environments. Its performance stability mainly depends on the following aspects:

High temperature resistance: Phenyl vinyl silicone rubber generally has high temperature resistance and can be used at higher temperatures for a long time without significant physical or chemical changes. This makes it widely used in high temperature environments, such as car engine rooms, hot water pipes, etc.

Chemical resistance: Due to the stable chemical properties of silica gel, phenyl vinyl silicone rubber usually has good chemical resistance and can resist the erosion of many chemicals, including acids, alkalis, solvents, etc. This makes it widely used in sealing and caulking in the chemical industry.

Weather resistance: Phenyl vinyl silicone rubber usually has good weather resistance and can resist the influence of natural environmental factors such as ultraviolet rays, oxygen, and water. This makes it widely used in outdoor building sealing, solar cell module packaging, etc.

Electrical insulation properties: Phenyl vinyl silicone rubber usually has good electrical insulation properties and can play a role in sealing and insulation of electrical equipment without causing electrical failures or short circuits.

In general, phenyl vinyl silicone rubber has high performance stability in extreme environments, but the specific stability needs to be evaluated based on specific usage conditions and requirements. When selecting and applying, factors such as material performance parameters, usage environment, and process conditions need to be taken into consideration to ensure that it can achieve the expected results and have long-term stability.
