What are silicone rubber sheets?

Silicone rubber sheets are polymer having both elasticity and viscosity which is formed by the mixture of carbon, hydrogen, and oxygen.

They are highly flexible, resistant to ultraviolet light, the ozone layer, weathering, and act as a highly electrical insulator.

Due to their extravagant characteristics, they are used in a broad range of applications.

They are used to create seals for electrical enclosures and in the manufacturing of gaskets to use in a high-temperature environment.

They are not suitable to use with acids, petrochemicals, and ketones and show poor resistance to tear and abrasion.
