What are the functional standards of Profile pvc?

The Profile Pvc is the home of the exterior wall insulation surface layer. The wall material mainly improves the mechanical strength of the surface layer, guarantees the resistance of the surface layer, continuously disperses the shrinkage pressure and insulation stress of the surface layer, avoids the concentration of application, and resists the cracking of the surface layer caused by natural temperature changes and accidental impact.

Therefore, the pvc corner bead plays a very important function and role in the insulation system, so when we choose and sell wall pvc corners, we choose high-quality materials interwoven. According to the technical standards of the industry's exterior wall insulation.

Its alkali-resistant tensile fracture uniformity shall not be less than 750N/50mm, and the alkali-resistant tensile fracture strength retention shall not be less than 50%, and the weight per square meter shall be ≥130 grams. When the pvc corners is used for crack control of exterior wall insulation, it not only requires the insulation layer material to have a certain tensile resistance and ultimate tensile strength, but also requires the material of the anti-cracking protective layer to have sufficient tensile strength.

When we choose pvc corner bead, it is necessary to pay attention to whether the tensile resistance of the Profile pvc itself meets the standard. The Profile pvc is made of alkali-resistant or medium Profile pvc as raw material, and woven into Profile pvc as the base material. It is then coated with acrylic copolymer liquid and dried to form a new type of alkali-resistant product.
