NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer CPE-135A, a high-quality chlorinated polyethylene specifically designed as a processing additive to significantly improve the performance of various plastic and rubber products, with a particular focus on rigid PVC applications. CPE-135A is derived from special high-density polyethylene (HDPE) through a controlled chlorination process, where chlorine atoms are partially introduced onto the HDPE molecular chain. This results in a white, free-flowing powder that is non-toxic and highly effective.

The primary function of CPE-135A is to act as a superb impact modifier and toughening agent for PVC. PVC, especially in its rigid form, can sometimes be brittle, limiting its use in applications requiring durability and impact resistance. By incorporating CPE-135A, manufacturers can dramatically enhance the toughness and impact strength of their final products. Beyond impact modification, CPE-135A imparts a range of other critical properties.

One of the key advantages is its excellent cold resistance, allowing PVC products to maintain their performance and integrity even in low-temperature environments where untreated PVC might become fragile. Furthermore, CPE-135A offers exceptional processing stability, which translates to smoother and more efficient production processes. It helps in achieving better melt uniformity and flow, reducing processing defects and increasing throughput. The additive also contributes to good aging resistance, ensuring the finished products retain their mechanical properties and appearance over time when exposed to environmental factors.

In addition to impact and cold resistance, CPE-135A demonstrates good chemical resistance and high-temperature performance, broadening the scope of applications where PVC can be successfully utilized. These properties make CPE-135A an indispensable component in formulations for a wide variety of PVC goods.

Technical specifications for CPE-135A powder confirm its quality and consistency. It presents as a white powder. Key indices typically include a chlorine mass fraction around 35±2%, minimal screenings (≤0.25%), low volatile content (≤0.5%), and controlled ash mass fraction (≤4.2%). Mechanical properties such as elongation (≥730%) and Shore A hardness (around 60) are also indicative of its effectiveness as a modifier, contributing to the flexibility and resilience of the final product.

CPE-135A from NINGBO INNO PHARMCHEM CO.,LTD. is versatile, finding widespread use in products such as PVC Profiles, Pipes, Cable jacketing, SPC (Stone Plastic Composite) flooring, WPC (Wood Plastic Composite) products, and general PVC and rubber goods. Its benefits are particularly pronounced in rigid PVC applications, where it significantly improves performance at usage rates typically ranging from 3 to 12 parts per hundred resin (phr), depending on the specific product requirements and desired property enhancements.

For PVC pipes and profiles, CPE-135A is crucial for increasing impact resistance, particularly important for pipes exposed to external stress or profiles needing durability against knocks and handling. In cable applications, it contributes to the flexibility, durability, and processing ease of the sheathing. For SPC and WPC flooring, CPE-135A adds resilience and toughness, enhancing their overall lifespan and resistance to damage.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that its CPE-135A meets stringent quality standards, backed by certifications such as SGS, ROHS, REACH, CE, and CNAS. These certifications underscore the product's compliance with environmental and safety regulations, providing customers with confidence in its quality and responsible manufacturing.

The product is typically supplied in durable Kraft Paper Waterproof Bags, each containing 25kg, though custom packaging options can be accommodated based on customer needs. Proper storage in a cool, dry warehouse away from direct sunlight and moisture, ideally below 40°C, is recommended to maintain its quality. Under suitable conditions, CPE-135A has a shelf life of two years, and performance inspection can determine usability beyond this period.
