Introduction:
Zinc Borate is environmental protection non-halogen flame
retardants, According to the difference of composition
(XZnO.YB2O3.ZH2O), FB flame retardant has more than ten varieties.
Through SGS testing, zinc borate is environmental protection type
non-halogen flame retardants. Zinc Borate can be used as a fire
retardant in PVC, Polyolefins, Elastomers, Polyamides, Epoxy
resins. In halogen-containing systems, ZB is used in conjunction
with antimony oxide, while in halogen-free systems; it is normally
used in conjunction with alumina trihydrate, magnesium hydroxide,
or red phosphorus. In some particular application Zinc Borate can
be used alone. The most commonly used variety is this product*3.5
water zinc, also know ZB****5, flame retardants. This product is
non-toxic, low-water-soluble, high heat stability, small particle
size, proportion small proportion, good dispersion characteristics,
as highly effective flame retardants is widely used in plastics,
rubber, paint and other fields.
Product
Applications:
1. Zinc Borate can be used as a kind of multi-functional
synergistic additive of Antimony oxide and other halogen flame
retardant ,can improve the nature of flame retardant effectively,
to reduce the smoke produced when combustion, and can adjust rubber
products chemical machinery, electricity and other aspects of
performance.
2. As the partial or completely environmental protection
substitute of containing halogen and other flame retardants , zinc
borate is being directly applied to a wide range of plastics and
rubber processing, such as PVC, PE, PP, enhance polyamide, PVC
resin, polyphenylene ethylene, epoxy resin, polyester resin acid
ethylene and natural rubber, styrene butadiene rubber, chloroprene
rubber. It can also be applied to the production of paper, fiber
fabric, decorative panels, floor leather, wallpaper, carpet,
ceramic glaze, fungicides, and paint production in order to improve
flame retardants performance.
3. Based on other natures, zinc borate, can also be
used for anti-corrosion, far-infrared absorption, and timbers
anti-pest and anti-bacteria handle and other fields.
