Key Technical Specifications

Manufactured under strict quality control for consistent batch performance:

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.
