The ideal silicone match of color, hardness, and standard!



Sterne manufactures and transforms different types of silicone rubbers, mainly available mainly available into two consistencies : High Consistency Silicone Rubber (HCR) and Liquid Silicone Rubber (LSR). Two major catalysts are predominant in the silicone industry : peroxide and platinum...

To define silicone rubber parts & products it is important to consider :
•    Final use
•    Hardness shore
•    Color
•    Temperature range
•    FDA or Industrial quality
•    Legal requirements
•    Other specific needs & constraints


Our range of solid silicone rubbers & Liquid silicone rubbers compounds
•    Hardness shore from 1 to 90 ShA+-5
•    Colors: translucent and riox being standard, Sterne proposes a large selection of colors: blue, black, white, special RAL colors which can also be counter typed
•    Temperature of fragility: all standard silicone have temperature of fragility from -60°C to +200°C, a large panel of silicone offers greater temperature of fragility: +250°C, +300°C, +400°C or lower temperature resistance, -110°C with Phenyl silicones
•    Standards: Sterne silicone can meet FDA, CE 1935-2004, USP Class VI, medical grade implantable for short or long term, metal detectable silicone rubber, low smoke toxicity and fire retardant answering specific norms for specific markets.
•    Transformation possibilities: molded by injection or compression, extruded, fabricated products, calendered

Our range of sponge silicone compounds
•    Density: 250Kgs/m3 is the standard, possibility of lower density of 200Kg/m3, or higher density of 400Kg/m3, even600Kg/m3 is possible
•    Colors: off-white is the standard, riox , black and a large selection of colors are available on demand
•    Temperature of fragility: all standard silicone have temperature of fragility from -60°C to +200°C, a large panel of cellular silicone offers greater temperature of fragility, +250°C, +300°C
•    Standard Sterne sponge silicone can meet FDA standards or low
