Atactic polypropylene glass fiber board is a kind of semi-rigid board made of glass fiber hand-drawn thick yarn as the main raw material, using a random polypropylene as a binder, leftovers of a petrochemical plant, through a special process. In addition to having all the characteristics of bituminous glass fiber board, this kind of board has a thermal conductivity of 20% lower. And because this kind of board does not need petroleum pitch and uses leftovers from petrochemical plants, the product cost can be greatly reduced. "Double material" comprehensive utilization of products.
Compared with bituminous glass fiber board, this kind of standard polypropylene glass fiber board has a slightly lower rigidity, but does not affect its performance. In order to keep the size stable and not deformed during transportation and storage, a layer of 5 can be coated on the surface of the board. Mm thick cement mortar protective layer solution. This not only increases the rigidity of the board, but also facilitates the bonding with the structural layer wall
