High quality Silicone Rubber for Moldmaking

1. Appearance: translucent or white viscous liquid.
2. Viscosity (Mpa·s (*5℃)): **********0
3. Hardness (Shore A): <= ****0
4. Tear strength (kn/m): >=*1
5. Elongation (%): >=**0
6. Shrinkage rate (%) <=0.1

Added with an appropriate amount of curing agent, the RTV silicone rubber cures at room temperature into elastic rubber. The cured rubber features resistance to high/low temperatures and aging, insulation, and waterproofness, and so on. It can be used at **0 ~ **0℃ for a long period.

1. Reproduction of models for copper crafts, gypsum products, handicrafts, decorative furniture, cultural relics, sculptures, candle crafts, etc.
2. Manufacture of lighting components and other transparent resin articles.
3. Production of leather or plastic floating flowers and elastic pads for transfer printing.
4. Manufacturing of soft shoe molds.
5. Elastic damping elements, and sealing coat of electrical elements.

1. Organic tin-based curing agents are commonly used for curing of RTV silicone rubber. General dosage: 2~3 parts of curing agent to **0 parts of rubber
2. The curing speed and curing agent dosage are related to ambient temperature and humidity. Generally, the less amount of curing agent and lower temperature and humidity, the slower the curing speed.
3. After mixing the RTV silicone rubber and the curing agent, the mixture shall be deaerated before use, or else it will affect the mechanical strength and electrical insulation properties of the cured silicon rubber.

1. Packaging: 5 kg plastic drum, *5 kg iron drum or tailored to customer requirements.
2. The product is not hazardous. Protect it from rain and sunlight during transport.
3. Keep it clean and protect it from dust, acid and alkali contact in storage.
4. Storage period: 1 year. If the product is kept beyond the shelf life, it can still be used after a quality control is performed.
