Room temperature vulcanizing silicone rubber compounds are a traditional mainstay of wacker silicones product portfolio.

Room temperature vulcanizing silicone rubber.

Our range of ready to use products for the numerous applications in the fields of bonding sealing potting encapsulation coating and mold making is accordingly impressive. While this rubber can render a wax pattern of exceptional detail it can also withstand the casting temperature of most tin. Other articles where room temperature vulcanizing silicone rubber is discussed. Manufacturers provide it in a range of hardnesses from very soft to medium usually from 15 to 40 shore rtv silicones can be cured with a catalyst consisting of either platinum or a tin.

Rtv 1 one component room temperature vulcanizing is based on a poly condensation reaction. However it has also grown to include the hardening of other synthetic rubbers via various means examples include silicone rubber via room temperature vulcanizing and. Room temperature vulcanizing rtv silicone rubber compounds are a traditional core competence of wacker. 1 as low molecular weight liquid room temperature vulcanizing rtv polymers that are interlinked at room temperature after being cast or molded into a desired shape or 2 as heat curable high temperature vulcanizing htv elastomers of higher.

The key difference between rtv and silicone is that rtv is a general term for room temperature vulcanizing silicone whereas silicone is a polymer material having repeating units of siloxane. Uncured silicone rubber is converted into elastomer by vulcanization. The latter being in most of the case an organic tin compound. The term originally referred exclusively to the treatment of natural rubber with sulfur which remains the most common practice.

The range of ready to use products focuses on numerous applications in the fields of bonding sealing potting encapsulation coating and casting. Vulcanisation refers to a range of processes for hardening rubbers.
