Shandong pvc Yixingguan pieces | Sea Widex (certified) | pvc Yixingguan pieces 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 pipe drying conditions: usually do not require drying. Melting temperature: 185 ~ 205C. Mold temperature: 20 ~ 50C. Injection pressure: can be as large 1500bar holding pressure: can be as large as 1000bar injection speed: To avoid material degradation, the general use of the injection speed considerably. Runners and Gates: All conventional gate can be used. If the processing of smaller components pvc Yixingguan parts supply, it is best to use the tip gate or sneak into the gate; for thicker parts, it is best to use the fan gate. The minimum diameter of the tip gate or sneak into the gate should be 1mm; fan gate thickness not less than 1mm. Typical uses: water pipes, pvc pipes Pipes household items, house siding, business machine housings, electronics packaging, medical equipment, food packaging. PVC light, heat stability is poor. Softening point of 80 ℃, begin to decompose at 130 ℃. Without heat stabilizer, polyvinyl chloride 100 ℃ began to decompose pvc Pipes Price, faster decomposition above 130 ℃. Thermal decomposition of the release of hydrogen chloride gas (hydrogen chloride gas is a toxic gas) it shaped molded fittings pvc color, from white to pale yellow → red → → → dark brown. The sun's ultraviolet light and oxygen causes oxidation and decomposition of PVC occur, thus making flexible PVC decline, finally brittle. From here is not difficult to understand why some PVC plastic over time will turn yellow, brittle reasons. Having stable physicochemical properties, insoluble in water, alcohol, gasoline, gas, vapor leakage low; at room temperature can be resistant to any concentration of hydrochloric acid, sulfuric acid 90% or less, 50-60% nitric acid and 20% or less caustic soda solution, has a certain resistance to chemical corrosion; for salts quite stable, but can be dissolved in ether, ketones, chlorinated aliphatic and aromatic hydrocarbons and other organic solvents.
