CPE 135A Mooney Viscosity ≤96ML 1 4 125C Elongation ≥600% Density 1.35 G/cm3 for Industrial in Temperature Environments

Product Description:

The CPE 135A is a high-performance PVC impact modifier designed to enhance the mechanical properties and durability of polyvinyl chloride (PVC) materials. This product appears as a fine white powder, making it easy to handle and incorporate into various PVC formulations. Its unique chemical and physical properties make it an ideal choice for manufacturers seeking to improve the impact resistance and flexibility of their PVC products without compromising other essential attributes.

One of the key features of CPE 135A is its remarkable elongation capability, which is ≥600%. This high elongation rate indicates the product's excellent flexibility and ability to stretch significantly before breaking. As a PVC impact modifier, this attribute is crucial because it allows PVC materials to absorb and dissipate energy from impacts more effectively, thereby reducing brittleness and enhancing toughness. This makes CPE 135A particularly useful in applications where PVC products are subjected to mechanical stress or impact, such as in pipes, fittings, profiles, and various rigid PVC items.

The chlorine content of CPE 135A is precisely controlled at 35±1%. This specific chlorine level is vital for ensuring compatibility with PVC resins, as it influences the chemical bonding and dispersion of the modifier within the PVC matrix. A chlorine content of around 35% ensures that the impact modifier integrates well with PVC, enhancing the overall material performance without causing phase separation or compatibility issues. This balance contributes to improved impact resistance, weatherability, and long-term stability of the end products.

Density is another important parameter of the CPE 135A product, measured at 1.35 g/cm³. This density value is indicative of the product’s molecular structure and packing, which affects its processing behavior and final performance in PVC compounds. A consistent density ensures predictable blending and processing characteristics, facilitating uniform dispersion within the PVC resin and resulting in consistent mechanical properties across production batches. This reliability is essential for manufacturers aiming to produce high-quality PVC products with consistent performance.

The heat of fusion of CPE 135A is ≤ 2.0 J/g, highlighting its low crystallinity and excellent thermal properties. A low heat of fusion means that the product has minimal crystalline regions, which contributes to its flexibility and impact-modifying capabilities. This characteristic is especially important during processing, as it allows for better flow and mixing with PVC resins at typical processing temperatures. The thermal stability afforded by this low heat of fusion helps maintain the integrity and performance of the PVC compounds even under elevated temperature conditions encountered during molding or extrusion processes.

As a PVC impact modifier, CPE 135A is engineered to improve the toughness and durability of PVC materials, which are inherently brittle without modification. By incorporating CPE 135A into PVC formulations, manufacturers can produce materials that resist cracking, chipping, and breaking, thereby extending the service life of the final products. This makes CPE 135A an indispensable additive in industries such as construction, automotive, electrical, and consumer goods, where enhanced impact resistance and durability are critical.

In summary, CPE 135A offers an excellent balance of physical and chemical properties tailored to enhance PVC materials. Its white powder appearance ensures ease of use, while its high elongation (≥600%) provides superior flexibility and toughness. The controlled chlorine content (35±1%) guarantees compatibility with PVC, and its density of 1.35 g/cm³ ensures consistent processing and product quality. Additionally, the low heat of fusion (≤ 2.0 J/g) contributes to its thermal stability and efficient processing behavior. Together, these attributes make CPE 135A a highly effective PVC impact modifier, ideal for improving the performance and longevity of PVC products across a wide range of applications.
