Century Multech, Inc.
Application
- Can be applied to a wide range of plastics and rubber processing, such as PVC, PP, PE, Nylon, PVC Resin, polyphenylene ethylene, epoxy resin, polyester resin, acid ethylene and natural rubber, styrene butadiene rubber, and chloroprene rubber.
- Can be applied to the production of paper, fiber fabric, decorative panels, floor leather, wallpaper, carpet, ceramic glaze, fungicides, and paint production to improve flame retardant performance.
- In halogen-containing systems, can be used together with antimony trioxide and alumina trihydrate.
- In halogen-free systems, can be used together with alumina trihydrate, magnesium hydroxide, red phosphorus, and ammonium polyphosphate.
- Also used for conveyor belts, wires and cables, intumescent coatings and paints, and anti-corrosive pigments.
Benefits
- Multi-functional synergistic flame retardant with antimony oxide.
- Can replace antimony trioxide as a synergist in both halogen-based and halogen-free systems.
- Anti-dripping and char-promoting agent, and suppresses afterglow.
- Suppresses arcing and tracking in electrical insulator plastics.
Packing
- 25 kg bags, 500 kgs bags, or 1000 kg bags available
- Store in a cool and dry place

- 4ZnO·B2O3·H2O
- 2ZnO·2B2O3·3H2O
- 2ZnO·3B2O3
*We can also offer particle size 2 µm, 8 µm, and 12 µm. But our 3 to 5 µm standard size can meet
most application requirements for zinc borate.
