Safety is a paramount concern across numerous industries, and for PVC products, achieving optimal flame retardancy is often a critical requirement. NINGBO INNO PHARMCHEM CO.,LTD. utilizes Chlorinated Polyethylene 135A (CPE 135A) as a key additive to enhance the flame retardant properties of PVC. This article will detail how CPE 135A functions as a highly effective flame retardant plastic modifier, contributing to safer and more reliable PVC end-products, particularly in wire and cable applications.

The flame retardant capability of CPE 135A stems from its chemical composition. As its name suggests, CPE 135A is a chlorinated polymer. The presence of chlorine atoms within its molecular structure inherently contributes to its flame retardant characteristics. When exposed to heat or flame, the chlorine atoms can interrupt the combustion cycle by releasing hydrogen chloride (HCl) gas, which acts as a radical scavenger in the gas phase, thereby inhibiting the spread of fire. This makes CPE 135A a valuable component for applications where fire safety is a priority.

While CPE 135A may not be classified as a primary flame retardant in the same way as some halogen-free compounds, its synergistic effect when combined with other flame retardant additives in PVC formulations is significant. It enhances the overall thermal stability of the PVC compound, allowing it to char more effectively. This char layer acts as a physical barrier, insulating the underlying material from heat and oxygen, and preventing the release of flammable volatile gases. This characteristic is especially important for wire and cable sheathing, where preventing fire propagation is critical for safety.

NINGBO INNO PHARMCHEM CO.,LTD. employs its technical expertise to formulate PVC compounds that incorporate CPE 135A to meet stringent safety standards. By carefully balancing CPE 135A with other additives, we can achieve excellent flame retardancy without compromising the essential mechanical properties, such as impact strength and flexibility, that CPE 135A also provides. This holistic approach ensures that our clients receive materials that are both safe and high-performing.

We are committed to pushing the boundaries of polymer technology to create safer, more reliable products. Through the strategic use of CPE 135A, NINGBO INNO PHARMCHEM CO.,LTD. helps manufacturers meet and exceed the demanding safety requirements of various industries, ensuring peace of mind for end-users.
