Platinum cure silicone rubber which is also named addition cure silicone rubber,is generally a type of two-part liquid silicone rubber vulcanized under room temperature. Platinum cure silicone rubber is non-hazardus,food-grade,and mainly used for mold making of foods(Candy,cake,chocolate,ice-cake,ect),jewelries,tires,rapid prototyping and vacuum foaming.Besides,it's most suitable for life-casting,such as human parts,sex-toys,silicone dolls,breast paddings,and so on.With a very tiny shrinkage,it's also popular for duplication of concrete blocks. With appropriate hardness,good tensile&tear strength,and exnt resistance to deformation,finished platinum silicone molds have not only a durable life but also a good performance...
Here are some properties of the rtv silicone.
1. Low viscosity for easy mixing,great for making simple one- or two-piece block molds.2. Perfect for art and industrial applications,often used for molds to reproduce sculptures and other prototypes, casting plaster, resins, and wax.
3. Very good fluidity for easy pouring operation.4. Stable quality & non-oily. 5. Good tension for easy de-molding.6. Good duplication with fine details.7. High performance in replication.8. Exnt resistance against heat, acid & alkali and aging.9. Low shrinkage.10. Long Shelf-life up to 12months.
