First, due to the amorphous material of the upvc profile, the moisture absorption is small, but in order to improve the flow profile and prevent the occurrence of bubbles, it should be dried first
The ways to improve the flexibility of plastic profiles include: adding plasticizers, blending flexible epoxy resins and polyurethane foaming flexible modified materials.
There are two main points in identifying the pros and cons of uPVC Profile. First, look at the appearance.
The UPVC profile should be a reasonably designed multi-cavity, with a wall thickness, and the formula contains anti-aging and anti-ultraviolet additives. From the appearance, it should have a smooth surface and a blue and white color.
The lead salt Window and Door Profile will form lead dust on the surface under the long-term action of sunlight and heat, which will cause lead poisoning and lead pollution.
