This formulation utilizes a precise blend of PVC resin, calcium carbonate, and impact modifiers to achieve a balance of rigidity and toughness. The panels exhibit excellent fire resistance, moisture proof performance, and thermal insulation properties. Surface treatments with UV stabilizers ensure long-term color stability, while lightweight construction facilitates easy installation. The product meets GB/T 8624-2012 standards and is ideal for commercial ceilings, bathroom claddings, and interior decorations.
The formulation for 200-400mm PVC water pipes is engineered to meet high-pressure performance requirements, incorporating a balanced blend of PVC resin (K value 65-70), calcium-zinc stabilizers, impact modifiers, and rigid fillers (calcium carbonate). Specialized lubricants (stearic acid + PE wax) ensure smooth extrusion, while processing aids (ACR 401) enhance melt strength for large-diameter pipe formation. This formulation delivers pipes with a minimum hoop strength of 16 MPa, excellent chemical resistance, and compliance with ISO 4422 standards, suitable for municipal water supply and industrial drainage systems.
