Polyvinyl Chloride PVC
Ultra-Fine Particle Size: PVC paste resin features extremely small primary particles (0.2–2 μm) and finished particle sizes of 30–80 μm, ensuring uniformity and excellent processing performance.
Excellent Dispersibility in Plasticizers: The resin can easily break down into primary particles when mixed with plasticizers, forming a smooth and stable paste, which is ideal for coating and molding applications.
Stable Paste Formation: When dispersed, it creates a consistent, paste-like fluid with good stability, supporting precise processing and high-quality end products.
High Processing Versatility: Its fine powder form and paste-forming ability make it suitable for a wide range of applications requiring controlled viscosity and smooth surface finishes.
Polyvinyl chloride (PVC) is one of the earliest commercially produced plastics. It is a thermoplastic polymer synthesized from vinyl chloride monomers. PVC appears as a white to light yellow powder, with a relative density of 1.35–1.40 and a chlorine content ranging from 56% to 58%. Its melting point is approximately 70–85℃. The material is soluble in or can be swelled by ketones, esters, tetrahydrofurans, and chlorinated hydrocarbons, and it exhibits excellent chemical resistance. However, its thermal stability and resistance to light are relatively limited. PVC resin is a widely used general-purpose thermoplastic, available in two main types: soft resin, which contains plasticizers (typically phthalates), and rigid resin, which does not include plasticizers. It finds applications in wire insulation, films, sheets, vinylon bricks, LP records, and pipes, as well as in items such as car mats, raincoats, and paint additives.

PVC is widely available, cost-effective, and offers excellent overall performance with a broad range of applications. When used as a plastic material, various additives—such as stabilizers, plasticizers, lubricants, fillers, and pigments—are incorporated according to specific performance requirements and end uses. Rigid PVC is commonly used to manufacture components and profiles, including corrosion-resistant pipes, valves, and ventilation equipment for chemical industries, as well as window frames, furniture, and agricultural products. Plasticized flexible PVC is suitable for producing wires, cables, and hoses, and when calendered into films, it can be used for rainwear, daily consumer goods, toys, packaging materials, and agricultural greenhouse coverings. PVC foam is applied in the production of plastic flooring, shoe soles, life-saving equipment, and thermal and acoustic insulation materials. Foam PVC artificial leather serves as a substitute for natural leather in products such as imitation leather uppers and sandals. PVC thermoplastic elastomers are used for car covers, bushings, and container door sealing materials. PVC fibers, also known as chlorofibers, are utilized in workwear, filter fabrics, carpets, and tents, and knitted underwear made from PVC fibers is reported to have certain auxiliary therapeutic benefits for rheumatoid arthritis.
