For procurement managers, R&D scientists, and product formulators in the chemical industry, a thorough understanding of material specifications is non-negotiable. Chlorinated Polyethylene (CPE) 135A, a critical component for enhancing polymer performance, demands a close examination of its technical data to ensure optimal application results. As a leading supplier of CPE 135A from China, we aim to demystify these specifications and highlight their importance for industrial use.

At the core of CPE 135A's functionality are several key technical parameters that dictate its suitability for various applications. The Chlorine Content, typically around 35% (e.g., 35±1% or 35±2%), is a primary indicator of its chemical structure and properties. A higher chlorine content generally correlates with improved flame retardancy and compatibility with polar polymers like PVC. Manufacturers seeking consistent quality will prioritize suppliers who accurately control this parameter.

Mooney Viscosity: A Measure of Processability

The Mooney Viscosity, often measured as ML (1+4) at 125°C, is a critical factor for processability. A lower Mooney viscosity, such as the typically cited ≤96 ML(1+4) 125°C for CPE 135A, indicates that the material is easier to process and disperses more readily within polymer matrices. This translates to smoother extrusion, better mold filling, and reduced processing temperatures, ultimately leading to improved manufacturing efficiency and product quality. When you buy CPE 135A, understanding its Mooney viscosity helps predict how it will behave in your specific processing equipment.

Mechanical Strength and Flexibility

When evaluating CPE 135A as an impact modifier, its mechanical properties are of utmost importance. The Tensile Strength, typically around ≥6.0 MPa, signifies the material's ability to withstand pulling forces without breaking. Equally important is the Elongation at Break, often ≥600%, which indicates the material's flexibility and capacity to deform before fracturing. These parameters are crucial for applications requiring toughness and resilience, such as in cable jacketing or flexible PVC components. A reliable China manufacturer will provide products that consistently meet these benchmarks.

Other important specifications include Heat of Fusion (indicating thermal stability), Volatile Matter Content (affecting purity and processing), and Shore Hardness (measuring resistance to indentation). For instance, a low volatile matter content (e.g., ≤0.75%) suggests a cleaner product, while a controlled Shore Hardness contributes to the overall mechanical profile of the compounded material.

When sourcing CPE 135A, it is imperative to work with manufacturers who provide detailed Certificates of Analysis (CoA) that clearly outline these technical specifications. As a dedicated supplier in China, we ensure that our CPE 135A products adhere to the highest quality standards, offering detailed technical data to support your formulation development. For any procurement manager or R&D scientist seeking reliable impact modifiers, understanding and verifying these specifications is the first step towards successful material selection.
