CPVC hot and cold water pipe application
Product Overview
Is a CPVC specialty compound developed by Nuvellis Chemtech for building domestic hot-and-cold-water supply pipelines, pressurized water supply pipelines and public-facility water distribution systems. Made from virgin materials with no recycled content added, it offers excellent high-temperature and pressure resistance, flame-retardant and self-extinguishing properties, and strong chemical corrosion resistance. Meeting drinking-water-grade hygiene standards, satisfies long-term pressure-bearing requirements.
The compound is compatible with conventional plastic pipe extruders and pipe-fitting injection molding machines. It plasticizes uniformly, flows well and molds smoothly with stable output, no precipitation and no scorching, helping pipe manufacturers consistently produce high-quality CPVC pipes.

Product Features
- Excellent Processing: Compatible with conventional pipe extruders and fitting injection machines; good melt flow, uniform plasticization, smooth molding, no precipitation and no scorching.
- High Temperature & Pressure Resistance: Vicat softening temperature ≥105°C, suitable for long-term hot-water and pressurized applications.
- Flame Retardant & Self-Extinguishing: UL94 V-0 rating; stops burning after removal of flame, improving building piping safety.
- Chemical Corrosion Resistance: Resistant to acids, alkalis, salt spray and oxidizing agents; after 1,000 hours immersion in 50% sulfuric acid at room temperature, mechanical strength retention rate ≥92%; resistant to common water-treatment agents with no degradation or leakage over long-term use.
- Drinking-Water Grade: Meets drinking-water hygiene standards for residential, commercial and public water supply systems.
- Consistent Quality: Stable dynamic properties, no recycled materials, high batch-to-batch consistency.

Packaging & Storage
Is packed in 25 kg kraft paper-plastic composite bags and should be stored in a cool, dry and well-ventilated environment. The product is hygroscopic; reseal the bag immediately after use to avoid moisture uptake. Follow general industrial hygiene practices during handling: avoid ingestion and eye contact, maintain adequate ventilation and dust control, and keep away from open flames and ignition sources. Refer to the MSDS for detailed information.
Processing Recommendations
For best results, we recommend drying before processing if it has been exposed to humid conditions, because the compound is hygroscopic. Use a conventional single-screw extruder with a suitable temperature profile for CPVC, keeping melt temperature and residence time under control to preserve heat stability and surface quality. Nuvellis technical team can provide starting extrusion parameters and screw-configuration suggestions based on your equipment model.
Quality Assurance
Each batch of is produced under controlled conditions and inspected for appearance, density, thermal stability and key mechanical properties. We provide a Certificate of Analysis with shipments so customers can verify compliance against the TDS values. Long-term supply consistency is ensured through standardized raw-material sourcing and process controls.
