Polyvinyl chloride (PVC) paste resin 9002-86-2 C2H3Cl PVC Pvc Resin

Basic Information

PVC paste resin, also known as polyvinyl chloride paste resin, is a fine white powder used primarily in the manufacture of plastisols. These plastisols are liquid dispersions of PVC particles in plasticizers and are used to create flexible and durable plastic products. PVC paste resin is valued for its versatility, ease of processing, and ability to produce products with a wide range of properties.

Physical and Chemical Properties

• Appearance: Fine white powder

• Polymerization Degree: Typically ranges between 1000 and 1800

• K Value: Usually between 65 and 72, indicating the molecular weight and degree of polymerization

• Viscosity: Varies depending on the specific grade, generally measured in mPa·s

• Density: Approximately 1.40 g/cm³

• Thermal Decomposition Temperature: Around 200°C

• Solubility: Insoluble in water, soluble in organic solvents like ketones and esters

Product Specifications

PVC paste resin is available in various grades, each tailored to specific applications. Common specifications include:

• K Value: A measure of molecular weight, influencing the viscosity of the resulting plastisol

• Viscosity: Important for processing and final product properties

• Particle Size Distribution: Affects the smoothness and consistency of the plastisol

Manufacturers typically offer detailed technical data sheets outlining these specifications for each product grade.

Applications

PVC paste resin is used in a wide range of applications due to its flexibility, durability, and ease of processing. Key applications include:

• Coated Fabrics: Used in upholstery, automotive interiors, and protective clothing

• Artificial Leather: Producing soft and durable synthetic leather for fashion, furniture, and automotive industries

• Wallpaper: Providing decorative and durable wall coverings

• Flooring: Creating resilient and easy-to-clean floor coverings

• Gloves: Manufacturing protective and medical gloves

• Toys: Used in the production of flexible and safe children's toys

• Sealants: For building and automotive industries, offering flexibility and adhesion

Storage and Handling

Proper storage and handling of PVC paste resin are crucial to maintain its quality and performance:

• Storage Conditions: Store in a cool, dry place away from direct sunlight. Ideal storage temperature is below 25°C.

• Packaging: Usually supplied in moisture-proof, sealed bags or containers to prevent contamination and moisture absorption.

• Handling Precautions: Use personal protective equipment (PPE) such as gloves, masks, and goggles to avoid inhalation and skin contact. Ensure adequate ventilation in the processing area.
