Polyvinyl Chloride Resin 702

Whatsapp Order

Polyvinyl Chloride Resin 702 is a high molecular weight, suspension-grade polyvinyl chloride resin with a K-value around 70–72. It is specifically formulated for use in soft and flexible PVC products due to its excellent plasticizer absorption and high mechanical strength. Its superior elongation, thermal stability, and processability make it highly suitable for calendaring, extrusion, injection molding, and dip molding operations. PVC Resin 702 is extensively used across the cable, synthetic leather, film, and footwear industries.

Polyvinyl Chloride Resin 702 (PVC)

Primary Uses

Flexible PVC Applications

Used in production of wires, cables, and flexible conduit sheathing due to its compatibility with plasticizers and high flexibility.
Applied in manufacturing soft tubing, hoses, and inflatable products for both industrial and consumer use.
Employed in making synthetic leather for upholstery, garments, and accessories.

Calendaring

Ideal for calendared products like decorative films, upholstery sheets, flooring tiles, and wall coverings.
Provides excellent surface smoothness and color retention.

Injection Molding

Used in production of flexible PVC footwear components, toys, and seals requiring high elongation and impact resistance.

Dipping Applications

Applied in glove manufacturing (household, industrial, and medical gloves) via plastisol dipping.
Used for handle grips, safety equipment coatings, and tool insulation.

Extrusion

Used for making flexible PVC profiles, tubes, edge bands, and soft trims.
Offers good melt flow and consistent dimensional stability.

Secondary Uses

Medical and Healthcare Products

Used in non-critical applications such as tubing, fluid transfer systems, and oxygen masks (when formulated with medical-grade additives).

Toys and Infant Products

Suitable for soft toys, bath items, and other flexible molded goods when stabilized appropriately for safety.

Packaging

Used in stretch films, cling wraps, and blister packs requiring good flexibility and clarity.

Automotive Interiors

Applied in dashboards, soft trims, and seat covering skins for UV-resistant, durable finishes.

Adhesives & Sealants

Incorporated into PVC-based adhesives to improve elasticity, flexibility, and bond strength.

Tarpaulins and Coated Fabrics

Used for outdoor fabric coatings requiring waterproofing and resistance to mechanical wear.
