Platinum Silicone Rubber

Silicone rubber platinum cure also known as addition cure silicone mold rubber platinums exhibit the lowest long term shrinkage and have the longest library life of all mold rubbers with a price tag to match.

Platinum silicone rubber.

Silicone molds and tubing are distinguished by the type of curing process they employ. These rubbers are chemically sensitive to latex. Platinum cure silicone also called addition cure silicone are two component high tear strength and flexible mold or casting compounds. As one of the leading platinum silicone rubber manufacturers and suppliers in china our factory also provides customized service and free sample.

Description of the platinum chemical reaction that forms 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. 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. The curing agents differ chemically to give the end product in this case silicone different properties.

Platinum cured silicone is favoured by many food beverage and medical industries due to the excellent purity the material offers. 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. As it contains no peroxide by products platinum cured silicone is non toxic as well as non yellowing. Buy platinum silicone rubber made in china here.

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. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. Welcome to check price and quotation with us. 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.

Peroxide cured silicone uses a process called free radical curing whereas platinum cured silicone uses addition curing.
