    the plastic material, wood-plastic mixed with different types of plastic, then made of wood-plastic material will be different Generally speaking, PE, PP, PS and PVC can be mixed into plastic made of wood and plastic. One of the most commonly used polyethylene (PE) and polyvinyl chloride (PVC). Polyethylene is chemically stable, resistant to dilute nitric acid, dilute sulfuric acid and any concentration of hydrochloric acid,white pine porch decking hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amines, hydrogen peroxide, sodium

    hydroxide, potassium hydroxide and the like at room temperature Solution. But not resistant to strong oxidizing corrosion, such as fuming sulfuric acid �� concentrated nitric acid, chromic acid and sulfuric acid mixture. At room temperature the above solvents will have a slow erosion of polyethylene, and at 90 --- 100 ��, concentrated sulfuric acid and concentrated nitric acid will quickly attack the polyethylene, fire resistant fencingso that its destruction or decomposition. Polyethylene under the action of the atmosphere, sunlight and oxygen, aging,

    discoloration, cracking, brittle or pulverized, loss of its mechanical properties. In the molding temperature, but also because of oxidation, the melt degree of decline, the occurrence of discoloration, streaks, and therefore in the molding process and the use of process or material selection should be noted. Precisely for these reasons,philippine ridge house roof design wood-plastic profiles made from mixed polyethylene (PE) are generally suitable for outdoor use. Polyethylene (PE) under the high-density polyethylene (HDPE) is a highly crystalline, non-polar thermoplastic
