Polyvinyl Chloride Masterbatch

Whatsapp Order

Polyvinyl Chloride Masterbatch is a concentrated mixture of pigments, additives, or fillers encapsulated in a PVC carrier resin, designed for direct addition into PVC processing applications. It offers an efficient and dust-free way to color, modify, or enhance the physical properties of PVC products. This masterbatch ensures excellent dispersion, consistent coloration, and improved processability. It is widely used in rigid and flexible PVC applications including construction, automotive, packaging, electrical, and consumer products.

Polyvinyl Chloride Masterbatch

Primary Uses

PVC Pipe and Fitting Industry

Used to color and stabilize rigid PVC pipes for water supply, drainage, and cable conduit systems.
Enhances UV resistance and impact strength of outdoor PVC products.

Construction Materials

Applied in window and door profiles, cladding, roofing sheets, and wall panels for coloration and weather resistance.
Improves surface finish, gloss, and appearance of finished profiles.

Wires and Cables

Incorporated in PVC sheathing and insulation to provide color coding, flame retardancy, and thermal resistance.

Flexible PVC Applications

Used in hosepipes, floorings, synthetic leather, and films for pigmentation and softness control.
Enhances printability and surface aesthetics in calendared sheets and flooring tiles.

Packaging Industry

Used in PVC blister packs, bottles, and rigid containers to achieve uniform color and improved mechanical properties.

Automotive Applications

Applied in dashboards, interior trims, mats, and door panels for color uniformity and UV stability.

Secondary Uses

Footwear Industry

Used in PVC shoe soles and uppers to provide consistent coloration and durability.

Medical Devices (Non-critical)

Applied in coloring tubing, fluid bags, and device housings made of flexible PVC (non-implantable, non-critical use).

Toys and Stationery

Used to impart safe, vivid colors to toys, erasers, and school supplies made from PVC.

Consumer Goods

Applied in buckets, basins, furniture components, and other molded household items.

Advertising and Display Materials

Used in signage boards, POP displays, and banner films for vivid, consistent color and weather resistance.
