Polyvinyl Chloride Resin 701 (PVC)

Primary Uses

Flexible PVC Products

Used in making cables, wires, hoses, and tubing due to its excellent flexibility and plasticizer compatibility.
Ideal for synthetic leather and flooring where softness, strength, and durability are essential.
Employed in production of raincoats, boots, and inflatable items requiring elongation and softness.

Calendaring Applications

Applied in the production of flexible films, sheets, and decorative foils.
Used in wall coverings, upholstery, and tablecloths requiring a smooth, printable surface.

Extrusion Applications

Utilized in manufacturing soft tubing for medical and industrial use.
Applied in flexible conduit systems and protective coverings for mechanical and electrical components.

Dipping and Coating Applications

Used in glove manufacturing (industrial and medical) through plastisol dipping.
Employed in coatings for tool handles, safety equipment, and textiles.

Injection Molding

Applied in soft, flexible molded items like gaskets, seals, and footwear components.

Secondary Uses

Medical Applications (Flexible Grade)

Used in non-critical components like blood bags, IV tubing, and oxygen masks (depending on purity and formulation).

Toys and Childcare Products

Applied in the production of soft toys and teething items with appropriate stabilizers.

Automotive Interiors

Used in dashboard skins, seat covers, and door panel coatings for flexible, weather-resistant surfaces.

Adhesives and Sealants

Added in formulation of PVC-based sealants and adhesives to improve elasticity and adhesion.

Textile Coating

Used in manufacturing waterproof fabrics, tarpaulins, and awnings.
