Solid silicone (HTV) is physiologically inert and may be used universally. "Solid" turns out to mean highly elastic – solid silicone is an auto-curing single component silicone caoutchouc. It is supplied in bales, blocks or strips and has good material properties. A summary of the most important properties: Shore A hardness ranging from 30 to 80 Seven standard colors are available, liquid silicone may be dyed at any color. starlim//sterner has defined seven standard colors for solid silicone. Temperature resistance: long-term (entire life-span of product) within the range from -50°C to 180°C and short interval 300°C (depending on the material: several hours). High temperature flexibility, solid silicone stays elastic even if temperatures vary greatly High level of extensibility (up to 1000%) High tear resistance and high value of compression set Good ozone and UV resistance which translates into good weathering properties and ageing resistance Low inflammability, flash point at 750
