CAS: 1332-07-6

 

Molecular formula: ZnB₄O₇

 

ZB2335 not only has low smokiness and good fire resistance, but also can greatly reduce the ash of rubber products (air-duct, belt conveyer) after burning. So it is the ideal substitute of antimony trioxide. It can achieve better fire retarding effect when used together with antimony trioxide.

1. Plastics: PVC, PVC ebonite foam, phenolic aldehyde, polyester, reinforced polyamide, polyurethane, polystyrene, PP, PE, ABS, epoxy resin, polyvinyl acetate etc.

2. Rubbers: natural rubbers, Styrene Butadiene Rubber, chloroprene rubber etc.

3. Paints: non-intumescent paints and intumescent paints.

4. Technology of nano-zinc borate has been developing rapidly and used widely in such fields of aerospace,home electrical appliance,light industry,electrons.
