Torr
offers a complete selection of cured and uncured calendered silicone
rubber sheeting.

|
:
available with a light fabric finish, unsurpassed in vacuum
and pressure bagging performance.
Commercial-grade compounds: available in a wide selection
of hardnesses and thicknesses, used in pressure-intensifier
and gasket applications not requiring high-strength properties.
Interflow™ breather pattern rubber: this patented
sheeting utilizes high-strength compounds, excellent for proccesses
where breather material is not an option.

Commercial
Grade Silicone Rubber Sheeting - Solid and Sponge
| |
Torr’s
commercial-grade silicone rubber sheeting is used for a variety
of applications such as pressure pads, shock absorption, gaskets
and items not requiring high tear and tensile strength. Custom
die cutting and perforating is available.
Because of the wide range of commercial-grade silicone rubber
available we group them by category of Solid and Sponge. Not
all compounds are in-stock, some lead time may be needed.

Interflow™
Breather Pattern Rubber
 |
Interflow
(patented) high-strength silicione rubber sheeting has a
gridwork of breather channels molded into the surface to
provide breathing in room temp, oven and autoclave processes.
Originally developed for laminating glass,
interflow is commonly used in compaction tables, metal bond
applications or anywhere part mark-off is not a concern.
Available in .125" EL78 and EL80 in widths of 36", 48"
and 54"
|
|
Interflow
Strips (commonly 5/8" wide) are also available. These
are frequently used on the perimeter of T7 tool diaphragms
to relieve stress on the diaphragm
