ZB2335

ZB2335, also known as 3.5 water zinc borate, has the chemical formula 2ZnO·3B₂O₃·3.5H₂O and a molecular weight of 434.62. It is an environmentally friendly non halogen flame retardant. It is non-toxic, low in water solubility, high in thermal stability, small in particle size, small in specific gravity, and has good dispersibility. It can efficiently flame retardant and smoke eliminate, and complies with EU RoHS and REACH regulations. It is widely used in the fire modification of polymer materials. ZB2335, with its excellent performance, has become an ideal flame retardant for industries such as plastics, rubber, and coatings.

Zinc Borate (ZB2335)Key advantages: High decomposition temperature , Loss on Ignition is less than 1% at 400℃ , and Zinc Borate (ZB2335) can be used in hightemperature processing .Zinc Borate (ZB2335) is used for polymer flame retardant systems with high processing temperature requirements such as high-temperature nylon, polyester, polyetherketone, polysulfone, and fluoropolymers whose processing temperature is higher than 290°C. Zinc Borate (ZB2335) can be Packaged Net weight 25kg/bag, Compound paper-plastic bag .
Shantong taixing are flame retardant china manufacturer and specialized in R&D and producing Environment-friendly halogen-free flame retardants with high quality and low price since 1998 , including Zinc Borate 233.5(ZB2335), Ultrafine Aluminum hydroxide, Melamine Cyanurate (MCA), Aluminium Hypophosphite(AP), Ground Aluminum hydroxide, Magnesium Hydroxide(MDH), Hexaphenoxycyclophosphazene (HPCP), Magnesium hydroxide ,we also produce flame retardant master batch and specialized flame retardant for GF reinforced PBT, PA and TPU.
