Why PVC Cable Material Zinc Borate 2335 Matters for Flame-Retardant Cable Compounds?

In modern electrical infrastructure, safety, durability, and fire resistance are essential for cable materials. One additive that has gained significant attention in the cable industry is PVC Cable Material Zinc Borate 2335. This compound is widely used as a multifunctional flame-retardant and smoke-suppressant additive in PVC cable formulations. By improving fire performance, thermal stability, and overall material safety, PVC Cable Material Zinc Borate 2335 plays an important role in the production of high-quality cables used in buildings, transportation systems, and industrial equipment. Manufacturers such as Shandong Taixing Advanced Material Co., Ltd. provide high-purity zinc borate solutions that help cable producers meet increasingly strict fire-safety standards while maintaining excellent mechanical performance.

What Is PVC Cable Material Zinc Borate 2335?

PVC Cable Material Zinc Borate 2335 is an inorganic flame-retardant additive mainly composed of zinc oxide and boron compounds. It is typically represented by the chemical formula:

2ZnO·3B₂O₃·3.5H₂O

This compound is commonly used in PVC cable compounds as a synergistic flame retardant that works together with halogenated or non-halogenated systems to improve fire resistance.

Key Characteristics

• Excellent flame-retardant synergy

• Effective smoke suppression

• Good thermal stability

• Low water solubility

• Environmentally friendly performance

Because of these properties, PVC Cable Material Zinc Borate 2335 has become a preferred additive for manufacturers producing high-performance cable insulation and sheathing materials.

How Does PVC Cable Material Zinc Borate 2335 Work in Cable Compounds?

The flame-retardant mechanism of PVC Cable Material Zinc Borate 2335 involves several processes during combustion.

Flame-Retardant Mechanism

1. Heat Absorption
   Zinc borate releases water molecules when heated, absorbing heat and lowering the combustion temperature.

2. Char Formation
   It promotes the formation of a protective char layer on the surface of PVC cables.

3. Smoke Suppression
   It reduces toxic smoke generation during burning.

4. Synergistic Effect
   Works effectively with antimony trioxide and other flame retardants.

This multi-functional mechanism significantly improves the fire safety performance of PVC cables.
