At NINGBO INNO PHARMCHEM CO.,LTD., we believe that a thorough understanding of material properties is fundamental to achieving optimal results. This article focuses on the technical specifications of Chlorinated Polyethylene (CPE) 135A, a key product in our portfolio that significantly enhances PVC and other polymer systems. Grasping the nuances of CPE 135A impact modifier properties allows manufacturers to fine-tune their formulations for specific performance requirements.

The chemical composition of CPE 135A is characterized by its chlorine content, typically around 35±2%. This level of chlorination is crucial for achieving the desired balance of properties, including impact modification, flame retardancy, and compatibility with PVC. The Chlorinated Polyethylene impact modifier for PVC benefits greatly from this specific formulation.

Thermal stability is another critical parameter. CPE 135A exhibits a high decomposition temperature, generally above 165°C, ensuring it can withstand typical PVC processing temperatures without premature degradation. This contributes to its effectiveness in improving the impact strength of PVC products and maintaining product integrity during manufacturing.

Key physical properties also define the utility of CPE 135A. It is supplied as a white powder with a low volatile matter content (≤ 0.4%), ensuring purity and consistency. The bulk density and particle size distribution are optimized for dry blending and uniform dispersion within PVC matrices, facilitating its role as a PVC processing aid. The low residue on sieving ensures a clean product, crucial for high-quality finishes.

Furthermore, the low temperature flexibility of chlorinated polyethylene is quantified by its performance characteristics, such as its Shore hardness, which typically remains low, indicating excellent pliability at reduced temperatures. This property is vital for outdoor applications where weather resistance of CPE for PVC is also essential. The combination of these attributes makes CPE 135A a superior choice for demanding applications.

As a cost effective PVC additive, CPE 135A provides exceptional value by enhancing product performance without significantly increasing costs. Manufacturers can rely on these detailed technical specifications to confidently integrate CPE 135A into their formulations, achieving superior results in terms of durability, processability, and overall product quality.
