Your Reliable Northern Industrial Partner
Description
◆ Zinc Borate - a new generation of eco-friendly synergistic flame retardant, with efficient smoke suppression and thermal stability at its core, provides an intelligent and long-lasting fire safety solution for demanding polymer systems, relying on its unique char-forming, heat-insulating, and low-toxicity environmental characteristics.
1. Synergistic Enhancement · Smarter
As an excellent flame retardant synergist, when compounded with various flame retardant systems (such as ATH, magnesium hydroxide, phosphorus-nitrogen systems), it can significantly improve the flame retardant rating, reduce the total additive amount, and enhance the thermal stability of the system.
2. Smoke Suppression and Anti-dripping · Safer
Releases crystalline water upon thermal decomposition and promotes the formation of a dense char layer, effectively suppressing smoke and flammable gas generation while preventing melt dripping, significantly enhancing fire safety.
3. High-Temperature Stability · More Durable
With a higher decomposition temperature and excellent thermal stability, it is suitable for engineering plastics with higher processing temperatures (such as nylon, PBT, etc.), ensuring the long-lasting and stable performance of materials during processing and use.
4. Eco-friendly and Low Toxicity · More Reassuring
Halogen-free and heavy-metal-free, with low emissions during combustion. It complies with stringent environmental and health regulations (such as RoHS, REACH), making it an ideal choice for pursuing sustainable and safe materials.

Zinc borate
Description: Zinc borate is an environmentally friendly non-halogen flame retardant, which is non-toxic, low-toxic, has good thermal stability, low release, and good dispersibility.
It is widely and directly applied in the processing of plastic and rubber products, such as the production of PVC, PE, PP, reinforced polyamide, polystyrene, epoxy resin, neoprene, paper, fiber fabric, decorative paper, wallpaper, electric board, ceramic glaze, paint, etc., to enhance flame retardant properties. It can also be used in fields such as anti-corrosion, insect and mold prevention treatment of OSB boards.
