Rigid PVC (Rigid Polyvinyl Chloride)

Rigid PVC Characteristics & Uses

Rigid PVC, also known as Rigid Polyvinyl Chloride, is a type of plastic made from polymerized vinyl chloride.It is a versatile, strong, stiff and cost-effective material that can be used for plastic injection molding, and is most commonly used in construction and industrial applications. It is one of the top 3 most widely produced polymers. It is a thermoplastic, which means that it can be easily molded and shaped when heated, and will retain its shape when cooled. It has good chemical resistance, weatherability, and electrical insulation properties, as well as many others, and can be made in a variety of colors and finishes.

Rigid PVC Applications

Rigid PVC is used in a broad range of applications, including:

Building & Construction
Exterior Siding
Windows
Piping
Pipe Fittings
Sprinkler Systems
Office Furniture Edging
Bottles
Non-Food Packaging
Cards, such as Membership or Bank Cards

Rigid PVC Advantages

Rigid PVC is a versatile thermoplastic resin that’s rigid and tough under ambient conditions. To allow injection molding, additives are mixed with PVC, including stabilizers, lubricants, processing aids, pigments, impact modifiers and fillers. Some of its other advantages include:

Good Strength
Flame Retardant
High Clarity
Good Outdoor Weathering Characteristics
Good Insulator
High Chemical Resistance
Low Flammability
Low Cost
Recyclable

Rigid PVC Disadvantages

Typically, lower molecular weight grades of this resin are used in injection molding as the high molecular weight grades are more difficult to process. It’s very important to process the material at the correct melt temperature to avoid decomposition and production of hydrochloric acid. Other limitations of Rigid PVC include:

Poor Thermal Capability
Sensitive to UV Degradation
Sensitive to Oxidative Degradation
Higher Molecular Weight Resin is More Difficult to Process
Stiff Flow Rate with Narrow Processing Range
