HTV (High-Temperature Vulcanizing) Silicone is also known as HCR (Heat Cured Silicone Rubber). You can mold these materials into various shapes and products. The bio-compatibility of silicone rubber is a critical key feature of rubber replacement. HT Series are high temperature vulcanized silicone rubber with high tensile and tear strength. Good anti-yellowing performance. Due to its indifference, it is used in many medical applications, including medical implants. It is bio-compatible, hypoallergenic and anti-allergic, making it suitable for baby care products and food contact in general. Depending on different properties, you can divide it into lots of varieties: general-purpose, high-tear strength, high and low-temperature resistance, low compression set, electrical wire and cable, solvent and oil resistance, flame retardant, electrical conductivity, and steam resistance etc.
Characteristic
1. Low molding temperature, 120°C~140°C, it can save energy, reduce the temperature of the workshop.
Product Advantages
1.High Temperature: Silicone rubber applicable temperature from -40°C to 230°C, it can be used in microwave and oven.
2.Easy to Clean: Silicone rubber finished products just need water to do cleaning.
3.Long Life: Silicone rubber stable in chemical properties.
4.Soft and Comfortable: Benefit from silicone rubber softness, mould products comfortable touch, extremel flexible and not deformed.
5.Environmentally Friendly: Silicone rubber does not produce and toxic or hazardous substances from raw materials to finished products.
6.Electrical Insulation Performance: Silicone rubber have high resistivity.
7.Low Temperature Resistance: Silicone rubber in - 60°C to - 70°C still have good elasticity. Our company has also developed some silicone rubber that can withstand lower temperature for mulations.
8.Conductivity: Silicone rubber have good conductivity when add conductive material (such as silicon dioxide).
9.Weather Fastness: Silicone rubber is not offected by ozone, long time in Ultraviolet light and other climatic conditions, its physical properties are only slight changed.
10.Thermal Conductivity: Silicone rubber have good thermal conductivity when add some raw materials.
11.Radiation Resistance: Radiation resistance of phenyl-containing silicone rubber is greatly improved.
