KE2004 Series of liquid injection molding system silicones

The KE2004 Series of liquid injection molding system (LIMSTM) silicones combines a low hardness with enhanced physical properties and improved processing control. Despite their low hardness, these silicones have high tear strength and viscosity, resulting in strong products with a soft feel. Their high tear strength allows for demolding of parts — particularly those with thin walls — without tearing and creating scrap. The materials were developed so that they could be pumped with an adequate injection speed, but still have a high enough viscosity to minimize flash and provide a balanced mold-flow. The KE2004-20 offers a high elongation of 870% and is compliant with food contact regulations (21 CFR 177.2600). The KE2004-5 and KE2004-10 are better suited in manufacturing such cushioning products as orthotics, cheek and forehead pads, and ergonomic and gel-like grips.
