PVC pipe fittings, sea Widex (certified), PVC pipe is provided by Qingdao Rubber Material Co., Widex. Widex Qingdao Rubber Material Co., Ltd. (www.haihuidaxiangsu.com) is specialized in "PVC profiles, seals, ABS extrusion profiles, PVC raw material" of the enterprise, the company of "honesty, hard service" concept, for You provide the most quality products and services. Welcome to inquire! Contact: Zhao Shuang. PVC is substituted with a chlorine atom using a polymer material of polyethylene, one hydrogen atom. Structure of this material is as follows: [-CH2 -CHCl-] n. Carbon atoms arranged in a zigzag, are σ-bonded to all atoms. All carbon atoms are sp3 hybridized low green plastic tubing formulation design, PVC plastic pipe certain principles for formulation. PVC macromolecular structure instability exists in the structure of the head structure, a branched chain, a double bond, allyl chloride, tert-chloride and the like, so that heat deformation resistance and poor aging drawbacks. After pretending to be cross-linked PVC pipe, can eliminate the disadvantages of the class. PVC rigid PVC sheet material and adding stabilizers, lubricants and fillers, after mixing PVC pipe, can be extruded with an extruder of various calibres hard pipe, shaped tube, bellows, used for water pipes, water pipes , wire casing or stair handrail. Good hot rolled sheet will overlap, can be made of rigid plates of various thickness. Sheet can be cut into the desired shape, then use hot air welding PVC welding rod into a variety of chemical-resistant tanks, ducts and vessels. Generally soft PVC products can be extruded by an extruder hoses, cables, wires, etc; the use of an injection molding machine with a variety of mold can be made of plastic sandals, shoes, slippers, toys, automotive accessories.
