Junzheng P-450 PVC Paste Resin
Certificate of Analysis
1. Product Introduction
P-450 is a low-medium K-value paste PVC resin specially produced for plastisol processing. It features moderate polymerization degree, stable low viscosity, low residual vinyl chloride monomer, few impurity particles and low volatile content. It has excellent plasticizer absorption and uniform mixing performance, widely suitable for artificial leather, coating, dipping, plastic wallpaper and other paste processing products.

3. Core Product Advantages
• Stable K-value and moderate polymerization degree, balanced plastisol viscosity, easy defoaming during production
• Extremely low residual VCM, meets environmental safety standards for daily-use plastic products
• Few impurity particles, effectively avoid surface spots and flaws on finished leather & coating products
• Low moisture and volatile content, no bubbles during high-temperature baking and molding
• Fine particle size distribution, good compatibility with all kinds of plasticizers, uniform paste formation
4. Typical Application Fields
• Artificial leather, PVC dipping gloves
• Plastic wallpaper, floor coating paste
• PVC plastisol coating, soft plastic molding products
• Vinyl toys, decorative surface coating materials
5. Packaging & Storage
Packaging Specification: 20kg per composite paper bag
Storage Requirement: Store in dry, ventilated warehouse, avoid direct sunlight and moisture; keep sealed after opening to prevent damp agglomeration.
6. Quality Statement
All test indicators are factory laboratory official inspection data and fully meet enterprise technical standards. Actual processing performance will be affected by plasticizer formula, stirring process and heating temperature. Small batch trial production is recommended before mass use.
