PVC K67
PVC K67 is a general-purpose polyvinyl chloride resin with a K-value of 67, indicating a medium molecular weight suitable for rigid applications. It is a white, free-flowing powder commonly used in the production of rigid PVC products such as pipes, fittings, profiles, and sheets. PVC K67 offers excellent processability, good mechanical strength, chemical resistance, and dimensional stability, making it ideal for a wide range of industrial and construction applications.
- Â Primary Uses
Building & Construction
- Used in manufacturing rigid pipes for water supply, drainage, and electrical conduit systems.
- Employed in producing window and door profiles, wall panels, and ceiling cladding.
- Utilized in manufacturing fittings, cable ducts, and other rigid structural components.
Industrial Fabrication
- Applied in the production of chemical tanks, linings, and trays due to its chemical resistance.
- Used in industrial ductwork and ventilation systems.
Packaging Industry
- Utilized in rigid film production for thermoformed packaging like trays, blisters, and containers.
- Used in non-food packaging for consumer goods and electronics.
Automotive Applications
- Used in production of rigid trim parts, instrument panel frames, and cable insulation conduits.
Consumer Goods
- Applied in the making of furniture edge bands, display stands, and rigid toys.
Secondary Uses
Medical Devices (Non-flexible components)
- Used in parts of disposable syringes, connectors, and other rigid m
