P-440 PVC Paste Resin with K-Value 75, Brookfield Viscosity ≤5000 and Ultra-low Residual VCM ≤10.0μg/g for Artificial Leather and Coating Applications

1. Product Introduction

P-440 is medium molecular weight PVC paste resin independently developed by Junzheng Group. It features K value 75 and average polymerization degree 1450±150, with stable plastisol viscosity, low residual VCM, few impurity particles and low volatile content. The resin delivers good tensile strength and compact film-forming property after gelation, suitable for compact surface layer of artificial leather, flooring leather and various coating plastisol products. It has wide compatibility with plasticizers, fillers and auxiliaries, applicable to medical, automotive, printing and coating industries.

3. Core Product Advantages

• Medium high molecular weight with K value 75, finished products possess excellent tensile strength, wear resistance and dimensional stability, ideal for compact surface layer materials.
• Stable low plastisol Brookfield viscosity ≤5000×10⁻³Pa·S, good fluidity for coating, dipping and casting processes, no thickening during short-term storage.
• Ultra-low residual vinyl chloride monomer ≤10.0μg/g, meets medical and food-contact environmental standards.
• Low volatile content and few impurity particles, effectively eliminate pinholes, speckles and surface defects of coated films.
• Moderate plasticizer absorption capacity, compatible with DOP, DINP and various inorganic fillers, strong formula flexibility.

4. Recommended Application Fields

• Artificial leather & flooring leather (surface compact layer)
• Tarpaulin, conveyor belt, glass fiber coating
• Disposable medical PVC gloves
• Wire & mesh coating, plastic toys, tool soft handles
• Automotive sealants & mastic, thermosetting adhesives
• Plastisol printing inks

5. Packaging Specification

• Standard package: 25kg moisture-proof composite paper bag
• Bulk ton package: 500kg / 1000kg flexible jumbo bag

6. Storage & Operation Safety Guidance

Storage Requirements

Store in dry, cool and ventilated warehouse, keep away from high temperature, rain and direct sunlight. Seal packages tightly after opening to avoid moisture absorption causing plastisol viscosity shift. Adopt FIFO inventory management.

Operation Safety

Wear dust mask, protective gloves and safety goggles during feeding and mixing to reduce dust inhalation. If powder contacts eyes, flush with plenty of clean water immediately.

7. Quality Statement

All listed data are factory typical reference values, not binding acceptance standards. Actual processing performance is subject to plasticizer ratio, mixing technology and storage temperature. Small batch trial test before mass production is highly recommended to confirm formula adaptability.
