door and window rubber steal strip what material is good
1. Plastic PVC sealant strip
the material is cheap and easy to get, with corrosion resistance, wear resistance, combustion resistance and high mechanical strength; The disadvantage is that the plasticizer in the matching system is easy to migrate, becomes hard and brittle with the extension of time, loses elasticity, and is not resistant to aging, poor weather resistance and low temperature performance. Generally, it is a dark product. It is suitable for occasions where the light is not strong, the temperature changes little, and the weather conditions are not bad.
2. EPDM sealant strip
excellent comprehensive performance, ozone proof, high temperature resistance, low temperature resistance, chemical resistance, resistance to various polar solutes, and low relative density. The disadvantage is that it has a large amount of expansion in general mineral oil and lubricating oil, usually dark products. The operating temperature range is-60 ~ 150℃, which is widely recognized in the industry for its excellent comprehensive performance. It can be applied to high temperature, cold, coastal areas, areas with strong ultraviolet radiation and middle-high building.
3. Thermoplastic vulcanizate sealant strip
with the flexibility and elasticity of rubber, it can be produced by plastic processing method without vulcanization, and the waste can be recycled and reused. It is a material with wide performance range. It has good heat resistance, cold resistance, low relative density, similar oil resistance and solvent resistance to neoprene, and is not very good in compression resistance, permanent deformation resistance and abrasion resistance. It can meet the requirements of various colors, and the operating temperature range is-40 ~ 150℃. Applicable to cold and middle-high building.

4. Polyurethane rubber sealing strip
it has good elasticity, excellent wear resistance, good oil resistance, wide adjustable hardness range (shore A hardness 65~80 degrees), and superior mechanical properties (tensile strength, Tensile Elongation), excellent cold resistance and chemical interwoven corrosion resistance, the price of raw materials is relatively high. Recyclable materials. It can meet the requirements of various colors. The operating temperature range is-60 ~ 80℃. It is suitable for areas with strong vibration such as earthquake-prone areas, near railways or factory buildings with high-power cranes, and areas with strong ultraviolet radiation.
5. Silicone rubber sealant strip
it has outstanding characteristics of high and low temperature resistance, ozone proof and weather resistance; It has excellent hydrophobic property and proper air permeability; It has unparalleled insulation performance; It can reach the hygiene level of food sanitary standard, it can meet the requirements of various colors. The disadvantage is that the mechanical strength is the worst among rubber materials and it is not resistant to oil. Operating temperature range-100 ~ 300℃. It can be applied to areas with high temperature, cold, strong ultraviolet radiation and middle-high building.
This is the place where door and window rubber steal strip is made of good materials. I hope it will be helpful to friends who have read it. If you want to know more, please continue to pay attention to this site.
