Model: PB-1000 | Brand: Zhongtai Chemical (Xinjiang, China)
Packaging: 25KG/BAG
Product Summary
Zhongtai PB-1000 is a PVC blending resin and viscosity reducing resin in the form of a white fine powder. With a K-value of 65, it is designed to reduce the melt viscosity of PVC pastes and dry blends, improving processing flowability. This resin is widely used in coating, dipping, slush molding, rotational molding, foaming, and special applications like automotive undercoating and sealants.
Key Features
- ✓ Viscosity Reduction: Significantly reduces melt viscosity of PVC pastes and dry blends, enhancing processing flowability.
- ✓ Excellent Dispersibility: Good blending and dispersibility, disperses uniformly without affecting appearance.
- ✓ Thermal Stability: Excellent thermal stability with high compatibility to PVC processing systems.
- ✓ High Whiteness: Suitable for color-sensitive products like white coatings.
- ✓ Low Migration: Low migration and blooming keeps product surface clean.
- ✓ Cost-Effective: Achieves ideal viscosity reduction at 20%-30% dosage.
