Core Features & Benefits

Superior Long-Term Thermal Stability‌: The advanced lead-based formulation in ‌WSD CHEMICAL's‌ stabilizer provides exceptional long-term heat stability, effectively preventing dehydrochlorination and polymer chain scission during high-temperature processing and throughout the product's service life, ensuring excellent initial color hold and minimal color shift over time.

‌Excellent Lubrication Balance (Internal & External)‌: This one-pack system is pre-balanced with optimized internal and external lubricants. It ensures smooth material flow, reduces torque and energy consumption, prevents plate-out on processing equipment, and guarantees a high-gloss, defect-free surface finish on the final product.

Outstanding Weathering & UV Resistance‌: Lead-based stabilizers inherently offer excellent resistance to UV degradation and weathering. Products stabilized with ‌WSD CHEMICAL's‌ PSM-31 maintain their mechanical properties and color stability when exposed to outdoor environments, making them ideal for building profiles and outdoor applications.

Excellent Electrical Insulation Properties‌: Provides superb electrical insulation, making it the preferred choice for PVC electrical conduit, cable duct, and other insulation applications where electrical safety is paramount.

Cost-Effective & Simplified Processing‌: The one-pack design eliminates the need for complex multi-component weighing and mixing, reducing formulation errors, saving labor costs, and ensuring batch-to-batch consistency. It offers an outstanding performance-to-cost ratio for high-volume production.

Primary Applications

PVC-U Pipes & Fittings‌: Pressure pipes, sewer pipes, and injection-molded fittings.

‌PVC Profiles‌: Window and door frames, siding, fencing, and decorative trim (especially for outdoor use).

PVC Rigid Sheets & Boards‌: Corrugated sheets, foam boards, and solid panels.

Electrical Conduits & Cable Ducts‌: Where excellent electrical properties are required.

‌Other Rigid PVC Extrusions‌: Technical profiles and industrial components.
