The production of high-quality Chlorinated Polyethylene (CPE) 135A is a precise chemical process that underpins its effectiveness as a premier impact modifier for PVC and other polymers. Achieving consistent properties requires stringent control over raw materials, reaction conditions, and purification. NINGBO INNO PHARMCHEM CO.,LTD is committed to manufacturing excellence, ensuring that every batch of CPE 135A meets the highest industry standards.

The manufacturing journey of CPE 135A begins with carefully selected high-density polyethylene (HDPE) as the base polymer. This HDPE is then subjected to a chlorination process, typically a suspension chlorination in an aqueous medium. During this stage, chlorine gas is introduced, and the reaction is meticulously controlled to achieve the desired degree of chlorination, which for CPE 135A is around 35%. The temperature, pressure, and reaction time are critical parameters that influence the final product's molecular structure and properties, including its excellent impact resistance and weatherability.

Following chlorination, the CPE polymer slurry undergoes several crucial steps, including neutralization, washing, and dewatering, to remove residual reactants and by-products. This purification process is vital for ensuring the product's purity and preventing contaminants that could negatively affect its performance as a plastic additive. The resulting wet cake is then dried to a fine powder, yielding the characteristic white powder appearance of CPE 135A.

Quality control is an integral part of the CPE 135A manufacturing process. NINGBO INNO PHARMCHEM CO.,LTD employs rigorous testing at various stages. Key parameters such as chlorine content, whiteness, volatile matter content, residue on sieve, impurity particles, tensile strength, and Shore hardness are regularly monitored. For instance, maintaining a chlorine content of 35±2% is crucial for optimal compatibility with PVC, ensuring the desired impact modification. Achieving high whiteness (≥ 85) also indicates a well-purified product.

The consistent quality of CPE 135A is what allows manufacturers to reliably improve PVC toughness and achieve excellent results in applications ranging from pipes and profiles to wire and cable sheathing. Its good oil resistance, flame retardancy, and low-temperature flexibility are direct outcomes of controlled manufacturing processes.

As a trusted supplier in China, NINGBO INNO PHARMCHEM CO.,LTD invests heavily in advanced manufacturing technologies and robust quality assurance systems. This dedication ensures that our customers receive CPE 135A that not only meets but often exceeds industry expectations for performance and consistency. The rigorous production of this flame retardant plastic material CPE guarantees its effectiveness as a superior additive.

In summary, the manufacturing of Chlorinated Polyethylene 135A is a complex but well-defined process that prioritizes precise chemical reactions and stringent quality control. This commitment to excellence ensures that CPE 135A remains a vital and high-performing component for enhancing the properties of PVC and rubber products across a wide spectrum of industrial applications.
