1. Plasticized polyvinyl chloride sealant strip
Materials are cheap and easy to obtain, with corrosion resistance, abrasion resistance, combustion resistance, high mechanical strength; The disadvantage is that the plasticizer is easy to migrate with the system, with the extension of time, hard and brittle, loss of elasticity, no resistance to natural weathering, poor resistance to weather and low temperature performance. Generally for dark products. Suitable for light is not strong, the temperature changes little, the climate conditions are not bad occasions.
2. EPDM sealant strip
Excellent comprehensive performance, with ozone resistance, high temperature, low temperature performance, resistenza chimica, resistance to a variety of polar solutes, the relative density is small. The disadvantage is that in general mineral oil and lubricating oil, the amount of expansion is large, generally dark products. The temperature range of -60 ~ + 150 °C, with its excellent comprehensive performance, has been widely recognized in the industry. It can be applied to high temperature, Freddo, coastal areas, strong ultraviolet radiation and high-rise buildings.
3. Silicone rubber sealing strip
Silicone rubber sealing strip hat Outstanding high and low temperature resistance, ozone resistance and resistance to natural weathering. Excellent hydrophobicity and appropriate air permeability; With or without comparable insulation performance; It can reach the hygienic level of food hygiene requirements and meet the requirements of various colors. The disadvantage is that the mechanical strength is the worst in the rubber material and is not resistant to oil. Use temperature range -100 ~ + 300 °C. It is suitable for high temperature, Freddo, strong ultraviolet radiation areas and high-rise buildings.
