1. Used in aluminum: an additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly.
2. Used in organic chemicals: silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants.
3. Used in electronic parts: silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
In plastic woven bags of about 10KG,250 KG and 1MT net each.
Applications of RTV-2 manual molding silicone rubber
It is mainly applied in manual mold design, PVC plastic mould, cement product mould, low melting-point alloy mould, alloy toy craft, plastic toy, craftwork, gift and stationery, big statue, cultural relic duplication and reproductions; pad printing orientation, electronic appliances vibration resistance, etc.
Features of RTV-2 manual molding silicone rubber
Low shrinkage,no deformation of the mould, good elasticity, the more moulds duplicated the better, etc.
