The main raw materials of the products are imported EPDM, which has good sealing, waterproof, fireproof, pest control, windproof, light blocking, collision avoidance and long service life. The special products are made of EPDM with good elasticity and resistance to compression deformation, , Ozone, chemical effect, wide temperature range (-40 ℃ ~ +120 ℃) of EPDM foaming and compact composite, contains a unique metal clamp and tongue deduction, strong Durable. In a variety of electrical plays a key role. 1, using microwave curing process once formed, smooth and beautiful appearance without traces. 2, with good elasticity and compression deformation, excellent anti-aging properties. 3, excellent flame retardant, low smoke, low toxicity. 4, product extrusion stability, high dimensional accuracy. 5, non-toxic, environmentally friendly, anti-aging high temperature, stable performance, summer and winter can maintain good performance.
