Zhongtai PB-1000 is a PVC blending resin powder designed to reduce the viscosity of PVC pastes and dry blends while maintaining good processing characteristics. With a K-value of 65 and controlled particle size distribution, it improves flow and dispersion in coating, dipping, slush molding, and rotational molding applications. Its low plasticizer absorption at room temperature and excellent compatibility with PVC homopolymer and paste resin make it a cost-effective solution for a wide range of PVC products.
Key Selling Points
Outstanding viscosity reducing performance:Significantly reduces melt viscosity of PVC pastes and dry blends, improving processing flowability and enabling efficient production.
Excellent blending & dispersion:Disperses uniformly in PVC matrix without affecting product appearance, ensuring consistent quality.
High whiteness:Suitable for products with strict color requirements such as slush-molded toys and white coatings.
Low migration & blooming:Keeps product surface clean and extends shelf life of PVC pastes.
Cost-effective modification:Ideal viscosity reduction achieved at recommended dosage of 20%–30%.
Versatile compatibility:Compatible with PVC homopolymer, paste resin, and additive systems.
