At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on offering a deep understanding of the materials we supply. Chlorinated Polyethylene 135A (CPE 135A) is a prime example of a versatile polymer with a unique set of properties that make it invaluable across numerous industrial sectors. This article delves into the key chemical and physical characteristics of CPE 135A and illustrates how these attributes are leveraged in various applications.

The foundation of CPE 135A's performance lies in its structure – a modification of high-density polyethylene (HDPE) through chlorination. This process introduces chlorine atoms into the polyethylene chain, transforming the originally crystalline HDPE into a more amorphous and rubber-like material. The chlorine content, typically around 35%, is critical. It imparts essential properties such as flame retardancy, oil resistance, and improved compatibility with polar polymers like PVC. This specific formulation of CPE, designated as 135A, is optimized for impact modification and as a synthetic rubber component.

Key physical properties of CPE 135A include its appearance as a fine white powder, its non-toxic and tasteless nature, and its excellent thermal stability. It possesses good resistance to aging, weathering, and chemicals, which are vital for applications exposed to demanding environmental conditions. Furthermore, CPE 135A exhibits a good balance of mechanical strength, flexibility at low temperatures (down to -30°C), and a relatively high decomposition temperature. These characteristics are a testament to its robust chemical structure, which minimizes susceptibility to degradation.

The synergistic combination of these properties dictates CPE 135A’s wide range of applications. As a PVC impact modifier, it enhances the toughness and processability of rigid PVC products used in construction, such as window profiles and pipes. In the realm of rubber applications, CPE 135A serves as a high-performance synthetic rubber, ideal for manufacturing wire and cable jacketing, automotive hoses, sealing strips, and various industrial rubber goods where oil, heat, and flame resistance are critical. Its ability to be blended with other polymers like PE and ABS further broadens its applicability, allowing for tailored material solutions.
