For R&D scientists, product formulators, and procurement managers, understanding the precise technical specifications of chemical raw materials is fundamental to successful product development and manufacturing. Chlorinated Polyethylene 135A (CPE 135A) is a sophisticated additive, and its performance hinges on specific properties. As a leading manufacturer and supplier, we provide critical insights into these specifications to help you make informed purchasing decisions.

The primary function of CPE 135A is as an impact modifier for PVC. Its effectiveness is largely determined by key parameters such as chlorine content, molecular weight, and particle size. Typically, CPE 135A possesses a chlorine content of around 35% ± 1%. This specific level of chlorination is crucial for achieving optimal compatibility with PVC and delivering superior impact strength, toughness, and weather resistance. Higher or lower chlorine content can alter its performance characteristics significantly.

Beyond chlorine content, other critical physical and chemical properties include:

• Appearance: CPE 135A is usually supplied as a white powder or granules, ensuring ease of handling and dispersion.
• Tensile Strength: A typical range for tensile strength might be ≥ 6.0 MPa, indicating its robustness as a component in plastic formulations.
• Shore Hardness (A): This parameter, often ≤ 65%, helps define its contribution to the flexibility and hardness of the final product.
• Elongation at Break: Generally ≥ 600%, this highlights its capacity to deform without fracturing, a direct measure of its toughening effect.
• Volatile Matter Content: A low volatile content (e.g., ≤ 0.4%) is essential for processing stability and to prevent undesirable emissions during manufacturing.
• Thermal Stability Time: This indicates how well the material withstands heat during processing, often measured at 165°C. A good thermal stability time ensures the material doesn't degrade prematurely.

When you decide to buy CPE 135A, understanding these specifications is vital for ensuring it meets your application's demands. A reliable manufacturer will provide detailed technical data sheets and certificates of analysis. We, as a prominent China-based supplier, are committed to transparency and quality.
