Information

Polyvinyl chloride resin, also known as PVC resin, is a white powder commonly used in the production of thermoplastics. It is a synthetic material widely used in the world today. Polyvinyl chloride resin has outstanding characteristics such as abundant raw materials, mature manufacturing technology, low price, and wide range of uses. It is easy to process and can be processed by molding, laminating, injection molding, extrusion, calendering, blow molding and other methods. With good physical and chemical properties, it is widely used in industry, construction, agriculture, daily life, packaging, electricity, public utilities, and other fields.

Polyvinyl chloride (PVC) resin can be processed into various plastic products. According to the purpose, it can be divided into soft and hard products. Rigid PVC has good tensile, flexural, compressive, and impact resistance, and can be used as a structural material alone. The flexibility, elongation at break, and cold resistance of soft PVC will increase, but the brittleness, hardness, and tensile strength will decrease. PVC resin is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.

Besides, PVC resins generally have high chemical resistance. It is very strong and resistant to water and abrasion. Therefore, this PVC material is very popular in the construction industry. It can be used to produce many items needed in the construction process. These items are generally lightweight, durable, and require no maintenance.
