<p>A silica-free liquid silicone rubber composition comprising: an organopolysiloxane polymer comprising units of the following general formula RnSiO(4-n)/2 in which each R group is the same or different and is selected from monovalent hydrocarbon groups having from 1 to about 18 carbon atoms wherein at least two R groups per molecule are either hydroxyl and/or hydrolysable groups or are unsaturated organic groups, and n is an integer having a value of from about 10 to 1500, having a viscosity of from 300 to 100000 mPa.s at 25oC The composition further includes an optionally treated kaolin filler a cross-linking agent, a catalyst; and where required optional additives. Elastomeric products produced using the above composition may be utilised in textile coatings such as airbag coatings, spark plug boots, key pads, oil resistant seals cookware, bakeware and general purpose seals, gaskets, diaphragms, moulded parts and high voltage insulators.</p> |
