Key Features of HPMC PVC Grade
Our HPMC for PVC stands out with its advanced formulation, tailored for demanding applications:
- Superior Dispersion and Stabilization: Forms a protective colloidal barrier during PVC suspension polymerization, preventing monomer droplet coalescence and ensuring uniform particle size distribution.
- Rheology Modification: Enhances melt flow and lubricity, reducing friction in extrusion and molding to minimize defects like plate-out.
- Thermal and Mechanical Enhancement: Improves PVC resin’s heat resistance and mechanical strength, extending product durability in high-stress environments.
- Eco-Friendly Composition: Derived from natural cellulose, non-toxic, biodegradable, and compliant with global standards such as REACH and RoHS.
- Customizable Viscosity Profiles: Available in various substitution degrees and molecular weights to match specific PVC formulations.
Applications:
Versatile and reliable, our HPMC for PVC is widely used across multiple sectors:
- Suspension Polymerization: Acts as a primary suspending agent in vinyl chloride reactors, producing high-quality PVC resins for pipes, profiles, and fittings.
- Extrusion and Molding: Serves as a lubricant and flow enhancer in manufacturing flexible PVC products like cables, flooring, and membranes.
- Compounding and Blending: Improves compatibility with fillers, pigments, and stabilizers in recycled or bio-based PVC composites.
- Specialized Uses: Ideal for foamed PVC insulation, medical-grade tubing, and automotive interiors requiring enhanced flexibility and biocompatibility.
Packaging:
25kg multi-layer paper bags with PE inner liner, or customizable options like big bags for bulk orders.
