Platinum Silicone Rubber

They are recommended as a mold material for casting polyurethane epoxy or polyester resins wax and a wide range of other casting materials.

Platinum silicone rubber.

Peroxide cured silicone uses a process called free radical curing whereas platinum cured silicone uses addition curing. Liquid silicone rubber lsr molds and tubing are becoming increasingly popular in manufacturing and a number of other industrial processes. The curing agents differ chemically to give the end product in this case silicone different properties. Platinum cure silicone also called addition cure silicone are two component high tear strength and flexible mold or casting compounds.

These rubbers are chemically sensitive to latex. As it contains no peroxide by products platinum cured silicone is non toxic as well as non yellowing. They exhibit extremely low shrinkage and high physical properties. Description of the platinum chemical reaction that forms silicone rubber.

Platsil rubbers are platinum cured also known as addition cure room temperature curing silicones rtv that are used to make flexible high strength molds and parts. Platinum cured silicone is favoured by many food beverage and medical industries due to the excellent purity the material offers. Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations. When we talk about platinum or peroxide curing in the silicone world curing is when the silicone rubber is chemically cross linked by means of the addition of a peroxide or platinum curing agent.

Buy platinum silicone rubber made in china here. The silicone industry extensively uses the platinum catalysed hydrosilation reaction in which a silicon hydrogen si h bond is added across an unsaturated carbon carbon double bond c c of an olefin resulting in the formation of a silicon carbon si c bond. Welcome to check price and quotation with us. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.

Silicone molds and tubing are distinguished by the type of curing process they employ.
