CAS No.9002-86-2
Polyvinyl chloride (PVC) is one of the five most widely produced and utilized general-purpose thermoplastic resins globally. Depending on whether plasticizers are added during processing, PVC is classified into rigid polyvinyl chloride (PVC-U) and flexible polyvinyl chloride (PVC-P). PVC boasts excellent flame retardancy, chemical resistance, mechanical strength, and electrical insulation properties, making it extensively used in building materials, piping, architectural profiles, medical packaging, wires and cables, and artificial leather, among other applications.

Made primarily from high-quality PVC resin and formed through an extrusion process. It has high mechanical strength, resists acid and alkali corrosion, has a smooth inner wall with low fluid resistance. It's lightweight, easy to install, long-lasting, and is widely used in water supply pipes, drainage and sewage systems, wire conduits, and communication cable channels.
Using a rigid modified PVC formula, it has good dimensional stability and excellent weather resistance. It's great for insulation and airtight/watertight performance, doesn't deform or fade easily, and can have steel reinforcement inside for extra strength. It's a popular choice for energy-efficient building doors and windows, as well as decorative panels.
Multi-layer composite structure, with a surface that's wear-resistant and non-slip, available in a variety of patterns. It's waterproof and moisture-proof, reduces noise and absorbs shocks, easy to install and maintain, and widely used for indoor flooring, wall decoration, ceiling panels, and commercial space flooring.
It’s highly transparent with a nice shine, shapes well, looks great on display, and also resists moisture and dust. Its softness and hardness can be adjusted, so soft products feel flexible, come in rich colors, are waterproof, easy to clean, and very durable. It can be made into clear packaging boxes, food blister trays, shrink labels for drinks, raincoats, tablecloths, slippers, and storage items through processes like thermoforming and calendering. It’s widely used in packaging and everyday consumer goods.
Made with PVC resin as the base material and mixed with additives like plasticizers and flame retardants. It has excellent electrical insulation, is flame-retardant and self-extinguishing, and is resistant to oil and aging. It processes well, can be soft or hard, and is suitable for insulation layers and outer jackets of low-voltage wires, control cables, communication cables, as well as insulating protective sleeves.
It’s resistant to chemical corrosion and has good sealing, so it can be made into industrial hoses, valve linings, anti-corrosion plates, and seals. It’s acid and alkali resistant, wear-resistant, and adapts to various industrial environments, making it widely used in chemical transport, equipment corrosion protection, and fluid pipelines.
Using non-toxic grade PVC materials that meet medical and health standards, it's safe, non-toxic, and biocompatible. It has high transparency and good flexibility, can be sterilized at high temperatures, and is commonly used in medical infusion tubes, blood bags, catheters, and various disposable medical supplies. It's one of the most widely used plastic materials in the medical field.
