Silicone Bonded Mica Sheet 0.5mm Thick x 300mm X 500mm

• High temperature insulation and heat protection material capable of 500°C.
• Excellent dielectric strength and electrical properties.
• Can be cut into components and parts to suit various applications.

Our Silicone Bonded Mica Sheet is a versatile and high-performance heat and electrical insulation material. It is made from a combination of muscovite mica bonded with a special silicone resin. The result is a rigid sheet that can withstand elevated temperatures and provide very good dielectric strength.

Because of its combination of thermal and electrical properties, Silicone Bonded Mica is used in a variety of areas. These include high temperature washers and gaskets, brake grid insulators, thermal and electrical barriers and more.

This type of mica sheet will withstand continuous temperatures up to 500°C plus short-term spikes to 600°C. It has a very low thermal conductivity that effectively prevents heat transfer.

Silicone Bonded Mica is a rigid sheet with good mechanical strength. At ambient temperatures it has a compressive strength of 350 MPa. It can also be cut, machined and drilled very accurately.

Applications for Silicone Bonded Mica Sheet

• Electrical and thermal insulation for high temperature ovens.
