Trelleborg S765 Silicone Rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone; Silicone Rubber
Material Notes:	Properties Excellent resistance to heat (dry air), at +200°C continuous and +220°C intermittent. Remains flexible at low temperatures of -70°C. Resistant to ultra-violet light, ozone and weathering. Exhibits low flammability and low smoke toxicity. Good electrical insulation properties. Silicone rubber is physiologically inert, thus making it the preferred choice of the medical, pharmaceutical and food processing industries. Silicones have comparatively low mechanical properties, tensile strength, elongation and tear strength, however they keep constant even at high temperatures but should not be used with high pressure steam. Resistance to chemicals; its resistance to oils and hydrocarbon products is fairly limited and similar to that of Chloroprene rubbers. Reasonable resistance to a whole range of general chemical products, but acids, alkalis, esters and ketones should be avoided. All information provided by Trelleborg
