Common seal materials
EPDM sealing strip
Integrated performance, with ozone resistance, weather resistance, high temperature, low temperature performance, chemical resistance, resistance to a variety of polar solutes, the relative density. Disadvantage is that in general, mineral oil and lubricating oil expansion volume, generally a dark products. Operating temperature range -60 ~ +150 ℃. Applicable to heat, cold, coastal, strong ultraviolet radiation areas and high-rise buildings. With its wide range of applications, integrated performance, windows and doors industry recognition at home and abroad.
Silicone rubber sealing strip
Has outstanding resistance to high and low temperature properties, resistance to ozone and weathering resistance; has excellent hydrophobic and proper ventilation; unparalleled insulating properties; can achieve food hygiene requirements for health level, to meet the requirements of various colors. Disadvantage is that the mechanical strength of the worst in the rubber material, not oil. Operating temperature range -100 ~ +300 ℃. Applicable to heat, cold, strong ultraviolet radiation areas and high-rise buildings.
Neoprene sealing strip
Comparison with other special rubber, individual performance satisfactory, but the overall balance of properties is good. Has excellent weather resistance, ozone resistance, heat aging resistance and oil and solvent resistance, good chemical resistance and excellent flame resistance, good adhesion. Poor storage stability, storage will occur during hardening phenomenon, cold is not good. Relative density. Generally black products. Are used in the oil resistance, heat resistance, environmental requirements. Operating temperature range -30 ~ +120 ℃.security ties
Nitrile rubber seal
Main feature is oil, solvent, but the impatience ketones, esters and chlorinated hydrocarbons and other media, elastic and mechanical properties are good. Disadvantage is that the ozone and oxidation easy to aging crack, cold, poor low-temperature resistance. Operating temperature range -30 ~ +120 ℃
Polyurethane rubber seal
Has good flexibility and excellent abrasion resistance, good oil resistance, hardness adjustable range (Shore A hardness of 65 to 80 degrees), mechanical properties (tensile strength, elongation at break) location, fine cold resistance and chemical resistance to corrosion intertwined, higher prices of raw materials. Of recyclable materials. To meet the requirements of various colors. Operating temperature range -60 ~ +80 ℃. For earthquake-prone areas, or near railway crane with power plants and other areas with strong vibration, and the strong ultraviolet radiation regions.
TPV sealing strip
A flexible and elastic rubber, plastics processing methods can be produced, without curing, waste recycling and re-use. Is a wide range of material properties, heat resistance, good cold tolerance, relative density, oil resistance, solvent resistance and neoprene similar to resistance to compression and abrasion etc very well. Can meet the requirements of various colors, temperature range -40 ~ +150 ℃. Applicable to the cold, as well as high-rise buildings.fixed length plastic strap seal
Plasticized PVC sealing strip
Materials cheap and easy to get, corrosion resistant, wear-resistant, acid and various chemical medium, burning resistant, high mechanical strength; drawback is easy to fit within the system plasticizer migration, hard brittle with time and lose flexibility, even in aging, weather resistance and poor low temperature performance. Generally dark products. Is not applicable to the light intensity, temperature changes little, climatic conditions are not bad situation.
