For procurement specialists, R&D scientists, and product formulators, a deep understanding of technical specifications is paramount when selecting chemical raw materials. Chlorinated Polyethylene 135A (CPE 135A), a vital impact modifier for PVC and other plastics, is no exception. Knowing the key technical parameters of CPE 135A, alongside its price and availability from a reliable manufacturer, empowers informed purchasing decisions. This article guides you through the critical specifications you should consider when you buy CPE 135A.

The chemical composition of CPE 135A is fundamental to its performance. The chlorine content, typically ranging from 35% to 36% (e.g., 35±1%), directly influences its compatibility, flexibility, and flame retardant properties. Higher chlorine content generally leads to better resistance to oil and chemicals, as well as improved flame retardancy. When you source CPE 135A, always verify this percentage against your application requirements.

Mooney viscosity is another crucial parameter. Measured as ML(1+4) at 125ºC, the Mooney viscosity of CPE 135A, often specified as being ≤96 ML, indicates its flow characteristics and processability. A lower Mooney viscosity generally means easier processing, better dispersion, and improved fluidity during extrusion or molding. This is particularly important for manufacturers looking to optimize their production cycles and achieve a smooth finish on products like PVC profiles and pipes. Understanding this metric helps in selecting the right grade from a supplier.

Other important technical indicators include tensile strength (often ≥6.0 MPa), elongation at break (typically ≥600%), and shore hardness (e.g., ≤65 Shore A). These properties collectively define the mechanical performance of the materials modified by CPE 135A. For instance, high elongation ensures the material can withstand deformation without breaking, crucial for flexible applications like wire insulation or sealing gaskets. The heat of fusion, typically ≤2.0 J/g, also signifies its thermal stability.

When engaging with a CPE 135A manufacturer, don't hesitate to request comprehensive technical data. Understanding these specifications allows you to accurately predict how CPE 135A will perform in your specific formulations and manufacturing processes. By carefully evaluating these technical details alongside competitive pricing and reliable supply, you can confidently purchase the most suitable CPE 135A for your business needs, ensuring optimal results and product quality.
