Quality of EPDM Seal Stripes

EPDM seal strip has excellent comprehensive performance, ozone resistance, weather resistance, high temperature resistance, low temperature resistance, chemical resistance, resistance to various polar solutes, and low relative density. The disadvantage is the large amount of swelling in general mineral oils and lubricating oils, generally dark products. It has been recognized by the domestic and foreign doors and windows industry.

Silicone rubber fender strips have outstanding resistance to high and low temperature characteristics, ozone resistance and weather resistance. In addition, it has excellent hydrophobicity, proper gas permeability and unsurpassed insulation properties. Fluoro foam sealing strip is made of pure polytetrafluoroethylene dispersion resin. It is made by stripping and high temperature stretching. It has low friction coefficient, good chemical resistance and good sealing performance. It can be used at temperatures from -250°C to +280°C. It is applicable to the sealing of reactors, steam generators and various special-shaped cans and barrels. This PTFE seal tape retains the excellent chemical resistance of PTFE, while it has excellent flexibility, compression recovery, excellent creep resistance, cold flow characteristics, and high tensile strength.

The PTFE elastic belt is made of pure polytetrafluoroethylene dispersion resin and can be used in areas with high temperature, cold, ultraviolet radiation, and high-rise buildings. Neoprene sealant Compared to other specialty rubbers, individual performance is worse, but the overall performance balance is good. Its advantages are excellent weather resistance, ozone resistance, heat aging resistance and oil and solvent resistance, good chemical resistance and excellent flame resistance, and good adhesion. However, its storage stability is poor, hardenability occurs during storage, cold resistance is poor, and the relative density is large. 

Use temperature range -30~+120°C polyurethane rubber seal strip It has good elasticity and excellent wear resistance, good oil resistance, wide adjustable hardness range (Shore A hardness 65-80 degrees), excellent mechanical properties (tensile strength, elongation at break), excellent cold resistance and chemical-resistant intertwined corrosion properties, recyclable materials , but raw materials are expensive. In addition, it can meet the requirements of various colors. Working temperature range -60~+80°C polyurethane rubber sealing strip It is suitable for areas with strong vibration such as earthquake-prone areas, near railways or factories with high-power cranes, and areas with strong ultraviolet radiation.
