Introduction

Polyvinyl chloride, commonly abbreviated PVC, is the third most widely used thermoplastic polymer. Around the world, over 50% of PVC manufactured is used in construction. As a building material, PVC is cheap, durable, and easy to assemble.

It can be made softer and more flexible by the addition of plasticizers, the most widely-used being phthalates. In this form, it is used in clothing and upholstery, and to make flexible hoses and tubing, flooring, to roofing membranes, and electrical cable insulation. It is also commonly used in figurines and in inflatable products such as waterbeds, pool toys or jump houses.

Valetime Group provides PVC Emulsion resins for the production of simulated and synthetic leathers.

 

PVC Resin Grades

K-Value 67 (E)

A medium molecular weight homopolymer paste PVC resin. At medium plasticizer levels, pastes made with this resin will exhibit medium viscosity, pseudoplastic flow at low shear rates and dilatancy at high shear rates. This resin is easily dispersed in plasticizers, and allows for an efficient removal of the air entrapped during the mixing operation. It is highly recommended for the manufacture of thick and high blow ratio foams.

Common uses include Cushioned vinyl flooring foam layers, Synthetic leather foam layers, Laminating adhesives for synthetic leather, Vinyl foam gaskets, Antifatigue walking floor mats.
 

K-Value 67 (A)

A medium molecular weight homopolymer paste PVC resin. Pastes made with this resin will exhibit high viscosity and pseudoplastic flow. This resin is easily dispersed in plasticizers, and allows for an efficient removal of the air entrapped during the mixing operation. Recommended in applications where limiting or avoiding dripping is a requirement; it is also recommended when tight control of paste penetration in the textile substrate is necessary.

Common uses include Synthetic leather foam layers -Laminating adhesives for synthetic leather-Printing inks for T-shirts- Fabric anchor coatings- Extra soft and thick vinyl foams, Viscosity and yield point enhancer for plastisols, replacing costly thixotropic agents.

K-Value 68 (G)

A medium molecular weight homopolymer paste PVC resin. At medium plasticizer levels, pastes made with this resin will exhibit low viscosity, pseudoplastic flow at low shear rates and slight dilatancy at high shear rates. This resin is easily dispersed in plasticizers, and allows for an efficient removal of the air entrapped during the mixing operation.

Common uses include Cushioned vinyl flooring foam layers, Synthetic leather foam layers, Coated fabrics, Laminating adhesives for synthetic leather, Articles made by rotational molding, slush molding, dipping or casting, Automotive Air and oil filters, Cap seals.

K-Value 74 (G)

A high molecular weight homopolymer paste PVC resin. At medium plasticizer levels, pastes made with this resin will exhibit low viscosity, pseudoplastic flow at low shear rates and slight dilatancy at high shear rates. This resin is easily dispersed in plasticizers, and allows for an efficient removal of the air entrapped during the mixing operation.

Common uses include Synthetic leather top coats, Foams for thermoformmable and embossable artificial leather, Wall coverings, Tarpaulins and conveyor belts, Articles made by rotational molding, slush molding, dipping or casting, Air and oil filters, Cap seals, Coated fabrics.
