PVC S60-61518 (Ethylene based - SG 8) - Taiwan

Brief Overview

Vinyl chloride serves as the monomer in the synthesis of the synthetic polymer known as polyvinyl chloride, or PVC. It is a thermoplastic substance with many uses since it can easily molded and sculpted into different shapes. PVC is widely utilized in the plumbing, electrical, medical, and building industries and is well known for its strength, durability, and chemical resistance. PVC is frequently used for vinyl siding for homes, electrical wire insulation, and water and sewage pipelines. Additionally, it is utilized in medical supplies including blood bags and tubing.

Manufacturing Process

PVC resin is a thermoplastic polymer that is widely used in many different industries because of its exceptional chemical resistance, affordable price, and long lifespan. The processes listed below are typically involved in the production of PVC resin:

1. Vinyl Chloride Monomer (VCM) Production: Ethylene is chlorinated in the presence of hydrogen chloride and oxygen to create volatile chemical monomers (VCM). The generated VCM gas is then stored and purified in order to be used in the next stage.

2. Polymerization: The next step is to polymerize the VCM gas, either by suspension or emulsion polymerization.

• A dispersion agent and a catalyst aid in the suspension of VCM droplets in water during suspension polymerization. The polymerization process is then started by heating the mixture while it is under pressure. After that, the PVC particles are dried, cleaned, and sorted by size.
• Emulsion polymerization is a method that uses a catalyst and an emulsifier to disperse VCM particles in water. The mixture is then rapidly heated and stirred to start the polymerization process. After that, the PVC particles are dried, cleaned, and coagulated.

3. Additives: Usually, PVC resin is mixed with other materials to enhance its characteristics. Among these additions are stabilizers, which stop deterioration during production and use; plasticizers, which increase flexibility; fillers, which lower prices and improve mechanical characteristics; and pigments, which add color.

4. Processing: To make the finished product, the PVC resin is then treated using a variety of techniques, such as extrusion, injection molding, and calendaring.

Applications

A thermoplastic substance with numerous applications across numerous sectors is PVC resin. It is quite flexible. The following uses of PVC resin are frequent:

1. Construction: PVC is widely utilized in the building sector due to its affordability, resilience to chemicals and weather, and durability in windows, doors, pipes, and siding.

2. Electrical: Because of its electrical qualities and fire resistance, PVC is widely utilized in the electrical sector for wire insulation, electrical conduit, and cable insulation.

3. Medical: Because PVC is clear, flexible, and biocompatible, it is a useful material for medical applications such as blood bags, tubing, and intravenous (IV) bags.

4. Automotive: PVC finds application in the automobile sector in a number of areas, including door panels, electrical insulation, and dashboard components.

5. Consumer goods: Because of its low cost, flexibility, and ability to withstand water, PVC is frequently used in the production of a wide range of consumer goods, including toys, inflatable items, and shower curtains.

6. Packaging: PVC is translucent and easily forms into many shapes, which makes it useful for packaging applications like clamshells and blister packing.
