SILICONE IS HIGH TEMPERATURE-RESISTANT, CHEMICALLY STABLE RUBBER

. . 

Features of Silicone rubber sheets :

 

• Extreme high and low-temperature resistance, can withstand -60 °C to +230 °C while maintaining physical and mechanical properties.
• Silicone rubber sheets are oven, microwave and freezer-safe.,
• Chemical stability,
• Moisture, ozone, UV light, and oil resistance are far superior to those of other rubbers, especially at high temperatures.
• Durable under general environmental distorting effects, no chipping or flex cracking.
• Good dielectric strength, however, can be formulated to be semiconducting,
• High gas permeability relative to other elastomers,
• Low compression set values, which mean less permanent deformation under thermal and mechanical stress,
• Smooth, water-repellent surface,
•  Good at shielding electromagnetic and gamma radiation. 
• High Transparency,
• Non-toxic, Odourless, and tasteless.
  Applications:ISheets of silicone rubber (generally 2 mm thick) are used in door and profile laminating and vacuum presses. 
  Thin sheets are used in respiration flaps for virus and bacteria protection in face masks.

• High gas permeability makes silicone sheets useful for applications where increased aeration is desired. 
• Baking mats made from high-grade silicone sheets are popular among households since they are microwave-safe and heat-temperature-befitted.
• Special apparel and footwear, especially sportswear, are prepared from fabric-reinforced silicone sheets due to their water repellent, ease of shaping, resistance to creasing and wrinkling, and high performance.
• silicone sheets are used as mattress protectors in homes and hospitals because of their g
