Polyvinyl chloride (PVC) is a ubiquitous polymer known for its versatility and cost-effectiveness, finding applications in construction, electronics, automotive, and consumer goods. However, like many polymers, PVC requires additives to enhance its performance, particularly in terms of fire safety. Zinc borate has emerged as a critical additive for PVC formulations, offering significant improvements in flame retardancy, smoke suppression, and thermal stability. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of high-quality zinc borate tailored for these demanding applications.

The primary role of zinc borate in PVC is as a flame retardant and smoke suppressant. When PVC products are exposed to heat, zinc borate decomposes, releasing water vapor. This process cools the material and dilutes flammable gases. More importantly, the resulting boron oxide forms a protective glassy layer on the PVC surface. This layer acts as a physical barrier, preventing oxygen from reaching the burning material and thus inhibiting combustion. This makes zinc borate an excellent choice for PVC applications where fire safety is paramount, such as wire and cable insulation, flooring, and construction materials.

Furthermore, zinc borate is a halogen-free additive, which is increasingly important as regulatory bodies and consumers push for safer and more environmentally friendly materials. Traditional PVC formulations often rely on halogenated flame retardants, which can release toxic gases when burned. Zinc borate provides an effective alternative, contributing to reduced smoke generation and the absence of corrosive byproducts. This is particularly beneficial for indoor applications where air quality is a concern. The effectiveness of zinc borate for PVC applications is further amplified by its synergistic effects with other additives commonly used in PVC compounding.

Beyond its flame retardant properties, zinc borate can also contribute to the thermal stability of PVC during processing. While PVC can degrade at high processing temperatures, zinc borate can help to stabilize the polymer matrix, reducing discoloration and maintaining mechanical properties. This makes it a valuable additive for ensuring product quality from manufacturing through to end-use. When considering the industrial grade zinc borate price, manufacturers find that the enhanced safety and processing benefits often outweigh the initial cost, especially for high-value or critical applications.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing zinc borate that meets the specific requirements of PVC manufacturers. Our product enables the creation of PVC materials that are not only safer and more compliant with environmental standards but also offer superior performance and longevity.
