Clear or Transparent Silicone Rubber

Although we usually think of silicone rubber as being pigmented red, black, or gray in color, it is also available in clear, transparent sheets and as custom molded parts.
Using our liquid injection molding (LIM) capability we can mold clear components in durometers from 10 to 70 Shore A.
For flat gaskets we suggest HT-6240, a clear, high purity, 40 durometer silicone rubber which we inventory in 36” wide rolls in .010”, .020”, .032”, .062”, and .125” thicknesses. HT-6240 is stored between two liners to maintain cleanliness.
A pressure sensitive acrylic or silicone adhesive can be applied to HT-6240. As with our other silicone rubber and sponge products Stockwell can supply a sample sheet or a prototype part cut on our water jet. For a data sheet on HT-6240 use the following link:

Transparent silicone can be used as an “invisible” gasket to enhance cosmetic appeal. Other uses include overlays, flexible laboratory covers, transparent membranes, and air flow diaphragms on respirators and ventilators.

I am trying to design a protective cover for glass pieces. The "skin" needs to be translucent so that you can see the designs on the glass. It needs to be thick enough to sustain a knock into something and be able to take a fall or being knocked over. It should be somewhat stretchable so it can be easily applied and removed for cleaning purposes.

Hi Alex,

The HT-6240 silicone is very clear and would offer some level of protection, however this is relative to the strength/type of your glass.
