PVC Paste Resin for Slush Forming Rotational DIP Forming

Product Description

 

Product Overview

PVC Paste Resin, also known as PVC plastisol resin, is a thermoplastic polymer derived from polyvinyl chloride (PVC). It is specifically formulated as a dispersion of PVC particles in a plasticizer, creating a viscous, paste-like consistency. This unique rheology makes it ideal for various coating, molding, and dipping applications.

1. Composition:

   • PVC polymer particles dispersed in plasticizers (e.g., phthalates, adipates).
   • Additives such as stabilizers (e.g., lead, tin, or calcium-based), lubricants, and pigments may be incorporated.

1. Properties:

   • High plasticizer content ensures flexibility and softness in finished products.
   • Excellent processability for dip-coating, spraying, or rotational molding.
   • Good chemical resistance (oils, solvents, abrasion) and durability.
   • Cost-effective compared to other thermoplastics.

2. Applications:

   • Coatings: Artificial leather, wall coverings, automotive upholstery, and floor tiles.
   • Molded products: Shoe soles, wire insulation, and packaging.
   • Dipping applications: grips, and protective coatings.

3. Processing:

   • Typically mixed with plasticizers, stabilizers, and other additives to form a plastisol.
   • Cured by heating (160-200°C) to fuse PVC particles into a solid, flexible film or product.

4. Safety & Environment:

   • Complies with international standards (e.g., REACH, RoHS) for additives and emissions.
   • Non-toxic in its cured state but requires proper handling during production (e.g., dust control).

Application Guide

 

Additional Insights on PVC Paste Resin:

PVC paste resin is highly regarded for its versatility in formulation, allowing manufacturers to tailor properties such as hardness, elasticity, and flame retardancy by adjusting plasticizer types and concentrations. For instance, aromatic plasticizers (e.g., DOTP) enhance flexibility, while aliphatic options improve UV resistance. Advanced formulations may also incorporate nanomaterials (e.g., TiO for opacity or clay for durability) to meet specialized industrial demands.
