Chlorinated Polyethylene (CPE) 135A is a highly versatile and essential polymer additive, widely recognized for its outstanding performance characteristics in various industrial applications. As a thermoplastic elastomer, CPE 135A is produced by the chlorination of high-density polyethylene (HDPE), resulting in a saturated thermoplastic resin with an irregular structure. Its unique chemical composition, typically with a chlorine content of 35% ± 2% (CAS No. 64754-90-1, Formula: [CH2-Chcl-CH2-CH2]N), grants it a remarkable set of properties that significantly enhance the durability and functionality of polymer-based products.

One of the primary advantages of CPE 135A is its exceptional impact modification capability. When incorporated into polyvinyl chloride (PVC) formulations, it dramatically improves the impact strength and toughness of the final products. This is particularly crucial for rigid PVC applications such as profiles, pipes, and sheets, where resistance to shattering and cracking under stress is paramount. The addition of CPE 135A ensures that these products can withstand harsh mechanical impacts and environmental conditions, extending their lifespan and reducing breakage rates.

Beyond impact resistance, CPE 135A offers a host of other beneficial properties. It exhibits excellent weatherability, providing superior resistance to UV radiation, ozone, and extreme temperatures, making it ideal for outdoor applications like roofing membranes and siding. Its inherent flame retardancy makes it a preferred choice for safety-critical components, especially in wire and cable insulation and jacketing, where fire resistance is essential. Furthermore, CPE 135A is lauded for its strong resistance to a wide range of chemicals, including acids, bases, and oils, ensuring product integrity in corrosive environments.

The physical characteristics of CPE 135A, supplied as a fine white powder, contribute to its ease of processing. It boasts excellent powder fluidity, good elongation at break (ranging from 600% to 1600%), and impressive tensile strength (6-11 MPa), which translates to highly flexible yet strong end-products. It can be easily blended with other polymers such as polyethylene (PE), acrylonitrile butadiene styrene (ABS), and various types of rubber, offering broad compatibility and enabling diverse material formulations without requiring vulcanization.

The extensive applications of CPE 135A are a testament to its versatility and high performance. It is indispensable as an impact modifier in a vast array of hard PVC products, including window profiles, water pipes, sewer pipes, and construction panels. In the rubber industry, it is blended to produce high-performance components for wire and cable jacketing, industrial and automotive hoses, and conveyor belts, where its resistance to heat, oil, and abrasion is highly valued. It also finds use in specialty applications like magnetic products, coated fabrics, and various injection-molded or extruded parts.
