What is zinc borate used for?
Zinc borate is used as a flame retardant in conjunction with other chemicals, including antimony trioxide, magnesium hydroxide, alumina trihydrate, and some brominated flame retardants. Zinc borate is used as a flame retardant on commercial furniture, draperies, wall coverings, and carpets (R.C.
Is zinc borate hazardous?
* Zinc Borate can affect you when breathed in. * Contact can irritate the skin and eyes. * Breathing Zinc Borate can irritate the nose and throat causing coughing and wheezing. Zinc Borate is a white powder.
How do you make zinc borate?
This zinc borate can be prepared by aqueous reaction of borax with a dilute zinc nitrate solution. A more practical method developed by industrial chemists is by a reaction of zinc oxide with boric acid in hot aqueous solution.
What is flame retardant properties?
Flame retardants are chemicals that are applied to materials to prevent the start or slow the growth of fire. They have been used in many consumer and industrial products since the 1970s, to decrease the ability of materials to ignite. Flame retardants are often added or applied to the following products.
Is boric acid a flame retardant?
Borate Value However, in the case of boric acid, a non-alkaline borate will react both as a fire retardant and smolder suppressant. Boric acid releases water as well to help extinguish the fire, but provides char forming value on the surface of the cellulose due to the presence of its boron value.
How do you use zinc borate?
Uses. Zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers and textiles. It is also used in paints, adhesives, and pigments. As a flame retardant, it can replace antimony(III) oxide as a synergist in both halogen-based and halogen-free systems.
What fabrics are fire retardant?
Nylon and Polyester Fabric Fire Resistance Synthetic fibers comprise most of the top choices for fire-resistant fabrics. While most natural fibers are flammable, plastic-based fibers will often melt due to the heat instead of igniting.
Is fire retardant carcinogenic?
There is growing evidence that many flame retardant chemicals can affect the endocrine, immune, reproductive, and nervous systems. Some animal studies have shown that long-term exposure to flame retardants can lead to cancer.
Can borax put out fire?
According to the American Borate Company, “boric acid, a non-alkaline borate will react both as a fire retardant and smolder suppressant. Boric acid releases water as well to help extinguish the fire, but provides char forming value on the surface of the cellulose due to the presence of its boron value.”
What is the CAS number for zinc borate?
Zinc borate Firebrake ZB (2ZnO·3 B 2 O 3 ·3.5H 2 O), CAS number 138265-88-0 Zinc borate Firebrake 500 (2ZnO·3 B 2 O 3), CAS number 12767-90-7 Zinc borate Firebrake 415 (4ZnO·B 2 O 3 ·H 2 O), CAS number 149749-62-2 ZB-467 (4ZnO·6B 2 O 3 ·7H 2 O), CAS number 1332-07-6
What is the specific gravity of zinc borate?
Zinc borate has a refractive index similar to most polymer systems, which results in the retention of considerable translucence. This allows the use of lower pigment loading as compared to antimony oxide. Zinc borate has a specific gravity of 2.77 and is considered to be low toxicity.
Is the white powder of zinc borate soluble in water?
Zinc borate appears as a white powder of variable composition. (typically 45% ZnO, 34% B2O3 and 20% H2O). Slightly soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment.
What can TCC Zinc borate be used for?
TCC’s zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers and textiles. It is also used in paints, adhesives, and pigments. As a flame retardant, it can replace antimony trioxide as a synergist in both halogen-based and halogen-free systems.
