CPE-135A is a specialized chlorinated polyethylene elastomer powder with a stable chlorine content of around 35%. Due to its highly compatible molecular structure with PVC resin and excellent compatibility, it has become a classic and widely used general-purpose impact modifier in the rigid PVC modification industry.

Unlike ordinary modifying agents, CPE-135A possesses excellent low-temperature toughening, weather resistance, ozone resistance, and impact resistance. It fundamentally compensates for the inherent defects of pure PVC material, such as high brittleness, easy cracking at low temperatures, and susceptibility to external force damage, comprehensively improving the overall mechanical properties and service life of PVC products.

In practical production applications, CPE-135A is compatible with various high-calcium powder-filled PVC formulations, effectively improving resin blending and plasticizing effects, resulting in more uniform and stable material plasticization. It prevents exudation, sticking to rollers, and clumping during processing, perfectly adapting to various processing techniques such as extrusion and injection molding. It completely solves quality problems in PVC pipes and profiles, such as brittleness at low temperatures, chipping during construction and installation, and aging damage after long-term use. Its superior weather resistance and aging resistance ensure that PVC products maintain stable toughness and structural strength even under long-term exposure to outdoor conditions, alternating high and low temperatures, and complex humid environments, significantly extending the service life of building materials.

Currently, CPE-135A is widely used in core building materials fields such as PVC water supply and drainage pipes and fittings, PVC-U window and door profiles, interior and exterior decorative panels, PVC foam boards, and wood-plastic composite products. It is also suitable for extended applications such as wire and cable sheathing, waterproof membranes, and plastic products.

Compared to high-cost impact modifiers such as MBS and ABS, CPE-135A offers excellent cost-effectiveness while ensuring superior toughening and modification effects. It boasts strong formulation compatibility, perfectly synergizing with various PVC stabilizers, lubricants, and processing aids. It easily meets various quality and safety standards in the domestic and international building materials industry, making it a core preferred raw material for cost reduction, efficiency improvement, and quality upgrading in the field of rigid PVC modification. It is also currently the most widely used and recognized PVC impact modifier product on the market.
