Silicone Rubber Sheet Density

Use them as flange gaskets and anywhere heavy compression would squeeze nonreinforced silicone rubber out of place.

Silicone rubber sheet density.

It is thermally stable over a wide range of extreme temperatures. Silicone rubber sheets and strips one layer of fiberglass cloth is inserted between two layers of silicone rubber to give these sheets and strips the strength to stand up to high stress and flex. Note that silicone rubber durometer is measured on the shore a scale. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.

In accordance with jis k 6249 test pieces. Commercial grade solid silicone sheet. 20 80 durometer. Supplied in sheets or continuous roll lengths.

Silicone rubber sheet is an inorganic synthetic elastomer made from a crosslinked silicon based polymer. Overview of materials for silicone rubber this property data is a summary of similar materials in the matweb database for the category silicone rubber. Our commercial grade silicone sheeting is designed for extreme temperature applications. 165 c x 10 min press cure 200 c x 4 h post cure 1 standard addition quantity is the quantity of curing agent added to 100 parts compound.

There are different types depending on functional groups in the structure and curing mechanisms. High density silicone rubber is harder and has a higher duromter. Each property range of values reported is minimum and maximum values of appropriate matweb. 2 linear shrinkage values differ according to the curing agent used.

Main applications are flexible seals o rings etc. Silicone s ability to remain elastic and rubbery makes this product highly valued in many industries. Fda grade white silicone sheeting is an outstanding choice for gaskets and seals because it has an excellent resistance to ozone oxidation ultraviolet light chemicals and a low compression set. Closed cell silicone sponge is formulated per ams3195 ams3196 astm d1056 mil r 6130 type ii astm d6576 type ii mil r 46089 ul94 hb ul94 v 0 and fda.

It offers a unique combination of chemical and mechanical properties organic to elastomers a like like gum rubber or inorganic elastomers like neoprene rubber can t match. Silicone sheet rubber solid sponge sheet. Softer rubber has a lower durometer. Automotive silicone foam medium density.

This specification covers silicone foam materials used for sealing various components within vehicles. Silicones are polymers with a si o si backbone. Supplied in sheets or continuous roll lengths.
