ASTM standard pvc pipe for drain 2 inch
PVC, also known as UPVC or PVCU, is composed of an amorphous thermoplastic resin prepared by polymerization of vinyl chloride monomer plus certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to the use of additives, the method of blending and modifying with other resins has been adopted, which has obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS, and so on. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. Its use ranks second among all kinds of synthetic materials in the world.
