Shore Hardness A below 64 percent CPE 135A compound volatile 0.75 percent heat of fusion less than or equal to 2.0 joules per gram

Product Description:

The CPE 135A is a high-performance PVC impact modifier designed to enhance the durability and flexibility of polyvinyl chloride (PVC) products. Known for its exceptional mechanical properties, CPE 135A serves as an ideal additive in various PVC formulations, significantly improving impact resistance without compromising the material’s inherent characteristics. This product is a specialized form of chlorinated polyethylene (CPE), engineered to meet the demanding requirements of modern PVC applications.

One of the standout features of CPE 135A is its impressive tensile strength, which is equal to or greater than 6.0 MPa. This high tensile strength ensures that PVC products modified with CPE 135A exhibit superior resistance to mechanical stress and deformation. The enhanced strength makes it suitable for use in applications where durability and longevity are critical, including construction materials, automotive parts, and electrical cables.

In addition to tensile strength, CPE 135A boasts an elongation at break of at least 600%. Such high elongation indicates excellent flexibility and stretchability, allowing PVC materials to absorb and dissipate energy efficiently under impact or strain. This property is particularly important for products subjected to dynamic loads or outdoor conditions where flexibility prevents cracking and failure over time.

The Shore hardness (A) of CPE 135A is maintained at or below 64, making it a relatively soft yet resilient impact modifier. This moderate hardness level contributes to the improved toughness of PVC blends while maintaining a balanced feel and processability. The softness of CPE 135A improves the overall handling and molding characteristics of PVC, facilitating easier manufacturing processes and enabling the production of complex shapes and designs.

Another critical attribute of the CPE 135A is its low heat of fusion, which is less than or equal to 2.0 J/g. This low heat of fusion signifies that the material requires minimal energy to undergo phase changes, thus contributing to energy-efficient processing and enhanced thermal stability of the final PVC products. The thermal properties of CPE 135A help in maintaining product integrity during extrusion, molding, or other thermal processing operations, reducing the risk of defects or degradation.

Visually, CPE 135A appears as a white powder, which is advantageous for blending and compounding with PVC resins. The white powder form ensures uniform dispersion throughout the PVC matrix, resulting in consistent impact modification and high-quality end products. This appearance also facilitates quality control during production, as any impurities or inconsistencies can be easily detected and addressed.

As a PVC impact modifier, CPE 135A is widely recognized for its capability to significantly enhance the impact resistance of rigid and flexible PVC formulations. By incorporating CPE 135A, manufacturers can produce PVC materials that are not only tougher and more durable but also maintain excellent processing characteristics and aesthetic appeal. Its role as a CPE-based modifier makes it a preferred choice for industries aiming to improve product performance while adhering to cost and environmental considerations.

In summary, the CPE 135A PVC impact modifier offers a comprehensive combination of high tensile strength (≥6.0 MPa), superior elongation (≥600%), moderate Shore hardness (A) (≤64), low heat of fusion (≤2.0 J/g), and a convenient white powder appearance. These attributes collectively contribute to making CPE 135A an indispensable additive for enhancing the impact resistance and overall performance of PVC products. Whether used in construction, automotive, cable manufacturing, or other industrial applications, CPE 135A stands out as a reliable and efficient solution for improving the toughness and longevity of PVC materials.
