PVC H58-3716 (Ethylene based - SG 8) - Taiwan

Brief Overview

The synthetic polymer known as polyvinyl chloride, or PVC, is made with vinyl chloride as the monomer. It is a thermoplastic material that can be easily molded and sculpted into a variety of shapes, giving it a multitude of applications. PVC is well known for its strength, resilience, and chemical resistance and is widely used in the plumbing, electrical, medical, and building industries. PVC is widely used for water and sewage pipelines, electrical wire insulation, and vinyl siding for homes. It is also used in medical equipment, such as tubing and blood bags.

Manufacturing Process

PVC resin is a thermoplastic polymer that finds widespread application across several industries due to its remarkable resistance to chemicals, reasonable cost, and extended lifespan. Typically, the following procedures are involved in the creation of PVC resin:

1. Vinyl Chloride Monomer (VCM) Production: In the presence of oxygen and hydrogen chloride, ethylene is chlorinated to produce volatile chemical monomers (VCM). Subsequently, the produced VCM gas is cleaned and stored in preparation for use in the subsequent phase.

2. Polymerization: The VCM gas has to be polymerized next, either by emulsion polymerization or suspension polymerization.

• During suspension polymerization, a catalyst and a dispersion agent help to suspend VCM droplets in water. Next, the mixture is heated under pressure to initiate the polymerization step. The PVC particles are then cleaned, dried, and arranged according to size.
• Emulsion polymerization is a technique that disperses VCM particles in water by using an emulsifier and a catalyst. Subsequently, the blend is heated and agitated quickly to initiate the polymerization process. The PVC particles are then cleaned, dried, and coagulated.

3. Additives: PVC resin is typically blended with other substances to improve its properties. Stabilizers to prevent deterioration during manufacturing and use, plasticizers to boost flexibility, fillers to reduce costs and improve mechanical properties, and pigments to give color are a few examples of these additions.

4. Processing: The PVC resin is subsequently processed utilizing a number of methods, including extrusion, injection molding, and calendaring, to create the final product.

Applications

PVC resin is a thermoplastic material with many uses in various industries. It is very adaptable. PVC resin is commonly used for the following purposes:

1. Construction: Because of its affordability, resistance to weather and chemicals, and durability in windows, doors, pipelines, and siding, PVC is widely used in the construction industry.

2. Electrical: PVC is frequently used in the electrical industry for wire insulation, electrical conduit, and cable insulation due to its electrical properties and fire resistance.

3. Medical: PVC is a helpful material for medical applications such blood bags, tubing, and intravenous (IV) bags since it is transparent, flexible, and biocompatible.

4. Automotive: PVC is used in the automotive industry for a variety of purposes, such as dashboard components, electrical insulation, and door panels.

5. Consumer goods: PVC is a common material for a variety of consumer goods, such as toys, inflatable objects, and shower curtains, due to its affordability, flexibility, and water resistance.

6. Packaging: PVC is utilized in packaging applications such as clamshells and blister packaging because it is transparent and readily molds into different shapes.
