At NINGBO INNO PHARMCHEM CO.,LTD., we understand the critical importance of material science in delivering high-performance products. One such essential component that bridges the gap between raw polymer and finished resilience is Chlorinated Polyethylene, specifically the CPE 135A grade. This sophisticated plastic additive is a game-changer in the realm of PVC modification, offering a robust solution to enhance the intrinsic properties of polyvinyl chloride.

The primary function of CPE 135A is to serve as a superior impact modifier for PVC. Rigid PVC, while offering excellent chemical resistance and rigidity, can be inherently brittle. The introduction of CPE 135A into PVC formulations dramatically improves its impact strength, preventing cracks and breaks under stress. This makes it an indispensable component for products that require exceptional toughness, such as window profiles, pipes, and siding. The ability to improve PVC impact strength is a testament to its advanced formulation.

Beyond impact modification, CPE 135A is also recognized for its excellent weatherability and aging resistance. This means that PVC products incorporating this additive will maintain their structural integrity and aesthetic appeal for longer periods, even when exposed to harsh environmental conditions like UV radiation and temperature fluctuations. This characteristic is vital for outdoor applications where durability is paramount, making it a preferred choice when seeking weather resistant plastic modifier solutions.

Furthermore, CPE 135A contributes significantly to the flexibility of PVC, a property often compromised in rigid formulations. This enhanced flexibility, particularly at low temperatures, ensures that products remain pliable and less prone to cracking. Its properties also extend to being an effective flame retardant, adding a critical safety layer to applications like wire and cable jacketing. The dual benefit of improved flexibility and flame retardancy highlights its versatility as a flame retardant plastic additive.

The production process of CPE involves the chlorination of high-density polyethylene (HDPE). This chemical modification process introduces chlorine atoms into the polymer chain, altering its molecular structure and imparting the desirable characteristics that make it an excellent modifier. This meticulous approach to material science ensures that manufacturers can achieve consistent and reliable results, whether they are looking for flexible PVC impact modifier options or robust solutions for extrusion processes.

In summary, the integration of CPE 135A into PVC manufacturing is a strategic decision that yields substantial benefits. From boosting impact resistance and flexibility to enhancing weatherability and flame retardancy, this chlorinated polyethylene is a cornerstone for producing high-quality, durable, and safe PVC products.
