For professionals in the plastics and polymer industry, understanding the technical specifications of chemical additives is paramount to achieving optimal product performance and efficient processing. Chlorinated Polyethylene (CPE) 135A, a key impact modifier and additive, possesses several critical parameters that dictate its efficacy. NINGBO INNO PHARMCHEM CO.,LTD. provides CPE 135A that adheres to stringent quality controls, ensuring manufacturers can rely on consistent and high-performing material.

One of the most significant specifications of CPE 135A is its Chlorine Content, typically around 35±1% or 35±2%. This parameter directly influences its compatibility with PVC and other polymers, as well as its flame retardant properties and impact modification capabilities. A precise chlorine content ensures predictable behavior during processing and optimal performance in the final application.

The Thermal Decomposition Temperature, often cited as being above 165°C, indicates the temperature at which the material begins to break down. This is crucial for determining safe processing windows. Products from NINGBO INNO PHARMCHEM CO.,LTD. are engineered to maintain stability within typical PVC processing temperatures, preventing premature degradation and the release of corrosive byproducts.

Volatile Matter Content, usually specified as less than 0.4% or 0.5%, refers to the moisture or residual solvent content. Low volatile content is desirable as it minimizes processing issues like foaming and ensures product purity. Our CPE 135A consistently meets low volatile content requirements, contributing to smoother manufacturing processes.

Particle size, often described by the residue on a specific mesh sieve (e.g., 20 mesh or 36 mesh passing percentage ≥99%), is vital for dispersion. Uniform particle size ensures that CPE 135A is evenly distributed within the polymer matrix, leading to consistent improvement in impact strength and other properties across the entire product. NINGBO INNO PHARMCHEM CO.,LTD. ensures a fine and uniform particle distribution for superior performance.

Other key specifications include Tensile Strength (e.g., ≥6.0 Mpa or ≥8.0 Mpa), which relates to the material's ability to resist stretching and breaking; Shore Hardness (e.g., ≤65 Shore A), indicating its resistance to indentation; and Heat Stable Time (e.g., ≥8 minutes at 165°C), a measure of its thermal stability during processing. The Bulk Density, typically around 0.50-0.55 g/ml, affects handling and storage efficiency.

Manufacturers looking to buy CPE 135A can trust NINGBO INNO PHARMCHEM CO.,LTD. to supply material that meets these critical technical specifications. By adhering to rigorous quality control measures, we ensure that our CPE 135A provides reliable and superior performance in your PVC and other polymer applications.
