产品详情
Polyvinyl Chloride (PVC Resin) is a widely used thermoplastic polymer synthesized from vinyl chloride monomer (VCM) through polymerization reactions. It is one of the most produced and versatile plastics globally, valued for its cost-effectiveness, durability, and adaptability to diverse applications.
Core Characteristics
- Chemical Structure
- Its repeating unit is −CH2−CHCl−, with the chlorine atom in the molecular chain endowing it with unique properties such as flame retardancy and chemical resistance.
- Key Properties
- Rigid vs. Flexible Variants: Unplasticized PVC (uPVC or rigid PVC) is hard, rigid, and has high mechanical strength, while plasticized PVC (flexible PVC) incorporates plasticizers (e.g., phthalates, non-phthalate alternatives) to gain flexibility, elasticity, and processability.
- Chemical Resistance: Resistant to most acids, alkalis, salts, and organic solvents, making it suitable for corrosive environments.
- Flame Retardancy: Inherently self-extinguishing (does not support combustion easily) without additional flame retardants, a major advantage over many other plastics.
- Low Cost & Easy Processing: Can be processed via extrusion, injection molding, calendering, etc., to produce a wide range of products.
Main Applications
Given its dual rigid/flexible nature, PVC is used across multiple industries, especially relevant to your product scope:
- Construction (Largest Application): uPVC pipes, window profiles, flooring, roofing membranes, and cable insulation—leveraging its weather resistance and durability.
- Packaging: Flexible PVC films for food packaging (e.g., cling wrap) and blister packs, as well as rigid PVC containers.
- Consumer Goods: Vinyl flooring, waterproof clothing, inflatable products, and toys (flexible PVC).
- Chemical & Industrial: Chemical storage tanks, linings for pipelines, and industrial hoses (benefiting from its corrosion resistance).
- PVC Resin Downstream Linkage: As a core raw material, PVC resin powder is compounded with plasticizers (your key product line) to produce flexible PVC products, forming a direct industrial application chain.
