In fact, expanded PTFE gasket is a kind of plastic gasket which is polymerized by the processing method of tetrafluoroethylene, so it is used in the production of major enterprises. The following small edition will introduce to you the advantages of expanded PTFE gasket.

Product introduction

1. Acid and alkali resistance: good acid and alkali resistance and corrosion resistance. It can be used even in high pH environment.

2. Strong water resistance: good water resistance, the product material itself is difficult to dissolve in water, and the water absorption is ≤ 5.7%,

3. Noise reduction: sound absorption and sound insulation are good. Insulation tile has good sound insulation, can reduce wind and rain noise, so that workers have a good working environment.

4. Bending resistance: the transverse bending resistance of the product is 3400n / m, and the longitudinal bending resistance is 310n / m.

5. Freeze and cold resistance: the content of magnesium oxide in the heat insulation tile is 50%, its thermal conductivity is 0.698, and it does not deform under the cold winter condition of - 40 ℃.

6. Fire resistance and high temperature resistance: the heat insulation temperature of this product can be reduced to 10 ~ 12 ℃ (indoor and outdoor temperature difference), because the raw materials are magnesium oxide, magnesium chloride and other inorganic raw materials. The magnesium oxide is white amorphous powder, odorless, with a relative density of 3.85 (25 ℃). The melting point is 2852 ℃, the boiling point is 3600 ℃, etc. it is a non combustible material, which is generally used to manufacture refractory bricks, refractory pipes, crucibles, steel-making furnaces and non-ferrous metal smelting furnaces And cement kilns.

6. Double faced lamination: the surface is covered with PET film, which increases the aging speed and weather resistance of the material, greatly increases the service life of the material, and the appearance is also beautiful.

8. Aluminum foil heat insulation tile: the aluminum foil film made of pure aluminum material is used, with smooth surface and good reflection. In the visible light range, the reflectivity reaches 70% ~ 80%, the reflectivity reaches 75%, and the insulation temperature drops 12 ~ 15 ℃.
