همچنین محصولات فرعی وجود دارد که پروفیل‌های اکسترود شده بر پایهٔ پلی‌وینیل کلراید سخت (یو پی‌وی‌سی) با مقاومت ضربهٔ بالا و سطح خارجی سفید هستند و در ساخت در و پنجره‌هایی که در دیوارهٔ خارجی ساختمان به‌کار می‌روند، استفاده می‌گردند.
PVC manufacturing requires a method often called polymerization, whereby monomers of vinyl chloride are chemically bonded to type a polymer chain. The two key different types of polymerization applied are suspension polymerization and emulsion polymerization.
On the other hand, PVC is recyclable underneath specific circumstances. It might be mechanically recycled by grinding it into small parts, that happen to be then melted and remolded. In some instances, PVC can also be chemically recycled, breaking it down into its constituent monomers for reuse.

The ensuing solution is refined to make pure white PVC. It might be recycled roughly 7 periods. Its lifespan is about a hundred and forty several years.
塩ビ樹脂溶液に皮膜を形成したいものを浸漬し、熱乾燥することで皮膜を形成できます。
聚氯乙烯可由乙烯、氯和催化劑經取代反應製成。由於其防火耐熱作用，聚氯乙烯被廣泛用於各行各業各式各樣產品：
پلی‌وینیل کلراید به‌وسیلهٔ پلیمریزاسیون مونومر وینیل کلراید شکل می‌گیرد. تولید تجارتی قسمت اعظم پی‌وی‌سی عمدتاً از طریق بسپارش تعلیقی انجام می‌شود و از بسپارش‌های توده‌ای و امولسیونی به میزان کمتر و از بسپارش محلولی به ندرت استفاده می‌شود. پلی‌وینیل کلراید از بلورینگی ناچیزی برخوردار بوده اما به علت زنجیرهای حجیم بسپار (نتیجهٔ استخلاف بزرگ کلر) از استحکام و سختی برخوردار است. تی جی برای آن بالا و به میزان ۸۱ درجهٔ سانتی‌گراد است ولی میزان این تی جی آن‌قدر بالا نیست که فرایند با روش‌های گوناگون را دچار مشکل کند.
Adaptable PVC is commonly used in building as insulation on electrical wires or in flooring for houses, hospitals, schools, and various regions in which a sterile surroundings is necessary. Rigid PVC is usually Utilized in construction as pipe for plumbing and siding that is usually identified as
Suspension Polymerization: This is certainly the most typical strategy Utilized in PVC output. It requires the initiation of your reaction by absolutely free radicals, leading to the polymerization with the vinyl chloride monomers suspended in water.
