|Silicone Rubber can withstand high temperatures without decomposing, has a wide operating temperature range, extremely good resistance to weathering, excellent electrical properties, good resistance to oils, easily colored, low level of toxicity. But it is not a very strong material, has poor resistance to fuels and is expensive when compared to other rubbers. Silicone Rubber is derived from the siloxane Polymer polydimethyl siloxane. This Polymer is an amorphous flowable substance which does not have useful properties. By adding a catalyst which causes the siloxane Polymer to cross-link, and adding a silica filler for strength, the Elastomer silicone is formed. The processes by which siloxane is converted to silicone are known as vulcanization or curing. There are two commercially significant curing processes, peroxide-curing and platinum-curing. |
Apex GB have over 20 years experience in manufacturing Plastic & Rubber Extrusions, Extruded Profiles and Tubing. We're quite rightfully proud of our reputation for consistently meeting the needs of customers over that time. Because we've remained small and focussed we've also remained more attentitive, more cost effective and more responsive than larger manufacturers.
