PSH-10 PVC Paste Resin Powder
Ultra-fine, low-viscosity PVC resin for efficient production
Product Summary
PSH-10 is a PVC paste resin produced via micro-suspension polymerization, featuring an average particle size of 1-2μm. This ultra-fine powder offers low and stable paste viscosity, making it ideal for high-speed stirring and long-term storage. It is widely used in vinyl toys, artificial leather surface layers, dip-molded trademarks, wallpaper foaming layers, and impregnated gloves. PSH-10 is certified under ISO 9001 and meets environmental standards for heavy metals, phthalates, and other restricted substances.
Key Features
- Ultra-fine particle size (1-2μm): Ensures smooth surface finish and high detail in molded products, enhancing product quality.
- Low and stable paste viscosity: Facilitates high-speed mixing and consistent application, improving production efficiency and reducing defects.
- Excellent compatibility with plasticizers: Works well with DINCH, DOTP, ATBC, TXIB, and Eastman additives, offering formulation flexibility.
- Versatile processing adaptability: Suitable for coating, foaming, dipping, casting, slush molding, and rotational molding, covering diverse manufacturing needs.
- Compliance with environmental standards: Low residual VCM (≤5 ppm) and meets heavy metal, phthalate, and other safety regulations, supporting export to strict markets.
