Silopren Electro 242-3 TP 3751 is a two-component liquid silicone rubber for injection moulding processes. This silicone rubber is particularly developed for the manufacturing of housing and weather sheds for all kinds of insulators

Key Features and Benefits
Vulcanisates consisting of Silopren Electro 242-3 TP 3751 are distinguished by the following properties:

outstanding ageing behaviour and weather resistance

fast hydrophobicity transfer and hydrophobicity recovery

rapid vulcanisation

excellent dielectric behaviour over a wide range of temperatures

very good tracking and arc resistance

very good flowability

high stability and flexibility at low temperatures

excellent stability to ozone and ultraviolet light

not readily combustible, does not melt or drip

easy pigmentable with LSR Colour Pastes

Potential Applications
Because of the outstanding properties Silopren Electro 242-3 TP 3751 is particularly suitable for the following elastomeric articles: suspension and long rod insulators, post line and pin insulators, surge arresters, hollow core insulators, high voltage plugs, cable connectors, fittings and terminals s.o.
