Description
Product Introduction: PVC E6644
Product Name: PVC E6644
Product Type: Emulsion Polyvinyl Chloride (Pasty Homopolymer)
Manufacturer: Arvand Petrochemical Company
General Description
PVC E6644 is an emulsion polyvinyl chloride with very fine particles and medium viscosity, designed to produce plastisols with slightly pseudoplastic rheological behavior. This material is ideal for creating chemically foamed products with fine cell structure and low density, and performs exceptionally well in applications such as screen printing, hot embossing, and foam wallcoverings.
Key Features
Medium viscosity with pseudoplastic behavior: Suitable for various coating processes
Fine and uniform foam cell structure: Enables low-density foams with smooth, white surfaces
Lower gelling temperature: Facilitates curing and improves processing efficiency
Stable foam production: Resists over-foaming even under varying process conditions
High filler compatibility: Maintains foam integrity even with high filler loading
Low sedimentation in paste form: Reduces bubbles and enhances final product quality
Recommended Applications
Due to its unique physical and rheological properties, PVC E6644 is ideal for manufacturing:
| Application Area | Usage Details |
|---|---|
| Foamed wallcoverings | Screen printing, hot embossing, smooth or textured surfaces |
| Interior decorative industry | Production of embossed and decorative vinyls |
| Lightweight foamed products | Flexible, low-density layers with good shape retention |
