2018-10-25 14:51:25

We all know that the choice of doors and windows in home decoration is very important. Because of their existence, we have a sense of security at home. The sealing strips of doors and windows need to be waterproof, sealed and energy-saving. It is soundproof, dustproof and antifreeze. It also has strong tensile strength, good elasticity, and better temperature resistance and aging resistance.

Nowadays, the door and window seal strips used in the market are many varieties, generally formed by PVC, modified PVC, EPDM, elastomer seals (including TPV, TPE, TPR, SEBS), silica gel, etc., mainly used in wood. Doors and windows, aluminum alloy doors and windows, plastic steel doors and windows and other architectural decoration doors and windows. The different performances of various door and window seal materials directly determine their scope of application. Today, Xiao Bian specially summarizes several of the commonly used materials that are most suitable for use in our homes.


1. Plasticized PVC sealant strip

The material is cheap and easy to obtain, has corrosion resistance, wear resistance, combustion resistance and high mechanical strength; the disadvantage is that the plasticizer in the system is easy to migrate, becomes hard and brittle with time, loses elasticity, is not resistant to aging, weather resistance and Poor temperature performance. Generally dark products. It is suitable for occasions where the illumination is not strong, the temperature does not change much, and the climatic conditions are not bad.

2, EPDM door frame foam tape

Excellent comprehensive performance, ozone resistance, high temperature resistance, low temperature performance, chemical resistance, resistance to multiple polar solutes, and low relative density. The disadvantage is that it has a large amount of expansion in general mineral oils and lubricating oils, generally dark products. The temperature range of -60 to +150 °C is excellent in its comprehensive performance and is widely recognized in the industry. It can be applied to high temperature, cold, coastal, strong areas of ultraviolet radiation and medium and high-rise buildings.
3, thermoplastic vulcanized rubber sealing strip

It has the flexibility and elasticity of rubber and can be produced by plastic processing without the need for vulcanization. The waste can be recycled and reused. It is a material with a wide performance range. It has good heat resistance and cold resistance, low relative density, oil resistance and solvent resistance, similar to neoprene, and resistance to compression set and wear resistance. It can meet the requirements of various colors, and the temperature range is -40~+150°C. Suitable for cold, medium and high-rise buildings.

4, polyurethane rubber sealing strip

It has good elasticity and excellent wear resistance, good oil resistance, wide range of hardness adjustment (Shore A hardness 65-80 degrees), excellent mechanical properties (tensile strength, elongation at break), excellent The cold resistance and chemical resistance of the interwoven corrosion properties, the price of raw materials is higher. It is a material that can be recycled. Can meet the requirements of various colors. The operating temperature range is -60 to +80 °C. It is suitable for areas with strong vibrations such as earthquake-prone areas, railways or factories with high-powered cranes, and areas with strong UV radiation.
5, silicone rubber sealant strip

It has outstanding high and low temperature resistance, ozone and weather resistance; it has excellent hydrophobicity and proper gas permeability; it has unparalleled insulation performance; it can meet the hygienic level of food hygiene requirements and can meet various color requirements. The disadvantage is that the mechanical strength is the worst in rubber materials and is not resistant to oil. The operating temperature range is -100 to +300 °C. It can be applied to high temperature, cold, strong ultraviolet radiation areas and medium and high-rise buildings.
Door and window seals look very inconspicuous, but they play a vital role in the family. It is recommended that you choose according to your own situation when you purchase.
