| Chlorine Content | 35 ± 2% | Optimized for maximum PVC compatibility and processing efficiency |
| Appearance | White powder | Clean, consistent color suitable for all pigmentation requirements |
| Tensile Strength | ≥ 6.0 MPa | Reliable mechanical integrity under load-bearing conditions |
| Volatile Content | ≤ 0.5% | Minimizes surface defects and processing bubbles in finished products |
Why Heat of Fusion Below 2 J/g Matters
The heat of fusion is a critical indicator of polymer crystallinity. CPE 135A with heat of fusion below 2 joules per gram exhibits extremely low crystallinity, which translates directly into superior industrial performance:
- Enhanced Low-Temperature Toughness: The near-amorphous structure maintains impact resistance at sub-zero temperatures, essential for outdoor components in cold climates.
- Superior PVC Compatibility: Low crystallinity promotes molecular-level dispersion within the PVC matrix, eliminating phase separation and improving compound homogeneity.
- Wider Processing Window: Reduced crystallinity allows smoother extrusion and injection molding at lower torque, reducing energy consumption and equipment wear.
- Consistent Impact Modification: Batch-to-batch consistency in heat of fusion ensures predictable performance, critical for quality-certified supply chains.
Shore Hardness 64 — Ideal for Industrial PVC Components
With Shore hardness of 64 (Shore A), CPE 135A delivers the ideal property balance:
- Sufficient Flexibility: Absorbs impact energy without brittle fracture, protecting PVC products from cracking during installation and service.
- Maintained Rigidity: Does not excessively soften the PVC compound, preserving structural integrity for pipes, profiles, and load-bearing components.
- Excellent Surface Finish: Balanced hardness contributes to smooth extrusion surfaces with minimal die lines and defects.
- Dimensional Stability: Components retain shape under thermal cycling and mechanical stress typical in industrial environments.
Recommended Industrial Applications
| Application | Benefit of CPE 135A |
|---|---|
| PVC Pipes & Fittings | Impact resistance for underground and pressurized piping; low-temperature durability |
| PVC Window & Door Profiles | Weather resistance and dimensional stability for long-service-life building components |
| PVC Industrial Sheets & Boards | High filler acceptance for cost-effective production without compromising toughness |
| Automotive PVC Components | Oil and chemical resistance combined with impact modification for under-hood parts |
| Electrical Conduit & Cable | Flame retardancy and electrical insulation for safety-critical applications |
