PVC Resins

Polyvinyl chloride (PVC) resin is a white powder that is commonly used in the production of thermoplastics. Its production frequently uses the suspension, mass, emulsification/dispersion, and solution methods of manufacturing. Products constructed using pvc resin can have a variety of characteristics, from being light and hard to being soft and flexible. The result is usually determined by the additives.

Frequently, additional ingredients are required to transform this resin into a finished good. These may consist of fillers, lubricants, and heat stabilizers. Plasticizers like butyl glycolate, epoxy resins, and dialkyl azelaate are among the most popular additives mixed with PVC. Plasticizers tend to make a material more malleable than it would be without them. Additionally, it is possible to improve puncture, tension, and chemical resistance.

Applications

PVC resins are widely utilized in the construction and infrastructure, agricultural, electrical products, and medical industries thanks to their durability, non-flammability, chemical resistance, and mechanical stability.

• Most rigid PVC resins are used in the construction industry for pipes and fittings.
• Rigid grades of PVC resin are used in profile applications in the construction and residential markets.
• Very small amounts of rigid PVC resins are used in bottles, credit cards, and other non-food packaging.
• With the addition of plasticizers, PVC resins can be used in flexible applications such as wire and cable insulation, signage, and many alternative rubber applications.
