The main chemical routes for vulcanisation of silicone elastomers are 1) Elevated temperatures cures and 2) Room temperature vulcanisation mechanisms. Organic peroxide cures are used in elevated temperature cures. Since the organic peroxides are inhibited by most carbon blacks, non black reinforcing fillers such as precipitated silicas, titanium dioxide and zinc oxide are used. Room temperature vulcanisation is normally used with low consistency silicone elastomers.

Rubber threads are susceptible to oxidative degradation, and high concentrations of antioxidants are added to the mixture to make the high surface area fibers more resistant. Pigments, such as titanium dioxide, are used as fillers or to impart whiteness to the thread. Carbon black reinforcement is used in colored rubber materials. Other agents include accelerators and activators to promote the vulcanization process. With all the additives, a typical high grade rubber thread contains less than 85% elastomer. 

One of the simplest approaches relies on the realisation of composite materials by filling an ordinary elastomer with a highly dielectric component (e. g. ceramics), it is possible to obtain a resulting material showing the combination of the advantageous matrix elasticity and filler permittivity. As an example, promising results have been obtained with a silicone elastomer mixed with a titanium dioxide powder [284]. 

Abstract This chapter describes the influence of three-dimensional nanofillers used in elastomers on the nonlinear viscoelastic properties. In particular, this part focuses and investigates the most important three-dimensional nanoparticles, which are used to produce rubber nanocomposites. The rheological and the dynamic mechanical properties of elastomeric polymers, reinforced with spherical nanoparticles, like POSS, titanium dioxide and nanosdica, were described. These (3D) nanofillers in are used polymeric matrices, to create new, improved rubber nanocomposites, and these affect many of the system s parameters (mechanical, chemical, physical) in comparison with conventional composites. The distribution of the nanosized fillers and interaction between nanofUler-nanofiUer and nanofiller-matrix, in nanocomposite systems, is crucial for understanding their behavior under dynamic-mechanical conditions.
