One layer of fiberglass fabric is sandwiched between layers of silicone foam giving these strips strength to handle high-stress applications, such as gasketing.

Stick this flexible tape to the back of welding seams to contain spatter and prevent oxygen, water vapor, and other gases from weakening the weld.

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