1, High mechanical intensity, so hardware part can be connected under the situation to bear the drawing-shearing strength.
2, Because of the heat expand coefficient is close to the aluminum profkles ones, so it is insured that the adiabatic strips can be tight joint with the aluminum profiles, even if during the large temperature difference.
3, High heat distortion temperature, so it is can be satisfied the follow-up treament of the aluminum profiles surface.
4, High dimension precision, so the airproof and waterproof of windows can be insured.
5, Super excellent anti-aging and anti-ultraviolet radiation ability, long life.
