Key words: XPS flame retardant, six brominated twelve alkane (HBCD), EPS (foamed polystyrene) flame retardant


Product introduction:
Six brominated ring twelve alkane (HBCD) is a kind of alicyclic flame retardant with high bromination content. It has many advantages, such as high flame retardant efficiency, wide application and sometimes no use of antimony synergist. Its low filling property has little effect on the properties of polymers, and ensures the excellent performance of polymers. A serious drawback of ordinary HBCD is poor thermal stability. HBCD without thermal stabilization is decomposed at 150 XPS, so it is not suitable for flame-retardant XPS, HIPS and PP thermoplastics.

[usage]: This product is used as XPS, EPS (expanded polystyrene board), flame retardant polypropylene fiber and styrene resin, can also be used as polyethylene, polycarbonate, unsaturated polyester plastics such as flame retardant additives, also suitable for fabric, styrene butadiene rubber, adhesive and coatings, unsaturated polyester resin for flame retardant.
[advantages]: it has a high flame retardant efficiency, a very small amount can achieve excellent flame retardant effect, no need to add other auxiliary flame retardants, meet the requirements of environmental protection, compared with the traditional flame retardant, it has a lower cost.


Use:
(1) EPS (foamed polystyrene) special.
(2) XPS extruded board special.
(3) special mother grain.
(4) the flame retardants of polypropylene fiber and styrene resin are also applied to the flame retardant treatment of fabrics, styrene butadiene gum, adhesives and coatings, and unsaturated polyester resins.


The product uses for polypropylene plastic and fiber, flame retardant polystyrene foam, can also be used for flame retardant flame retardant polyester fabric finishing PVA coated and double-sided leather. It is used as a kind of additive. It is suitable for polystyrene, unsaturated polyester, polycarbonate, polypropylene, synthetic rubber and so on.


Six bromo ring twelve alkane (HBCD) is a high bromine content of alicyclic additive flame retardant. It has the characteristics of low consumption, good flame retardancy and little influence on physical properties of materials. Mainly used for EPS (expanded polystyrene, polypropylene (reference dosage 2%), dosage 2%HBCD, 1% three two oxide antimony) and other styrene resin, but also demonstrated its excellent performance. In addition, it is applicable to knitted fabric, SBR, adhesives and coatings, and unsaturated polyester resin for flame retardant.
Character：
Six bromo ring twelve alkane (HBCD) is a white powder or particle. It is soluble in acetone, ester and other organic solvents, and has good stability to heat and ultraviolet light.  The flame retardancy of the product is higher than that of brominated aromatic flame retardant, and the thermal stability is higher than that of bromine aliphatic flame retardant.


Characteristic：
Six bromo twelve alkyl ring (HBCD) is a kind of high bromine content of alicyclic additive type flame retardant, it has high flame retardant efficiency, small dosage can achieve excellent flame retardant effect, without adding other auxiliary flame retardant; meet the requirements of environmental protection; compared with the traditional flame retardant, with low added cost the physical properties of the materials, the characteristics of small effect.


Main uses:
I produced six bromo twelve alkyl ring series products, including melting products, high melting products and heat stable products, mainly used in EPS (expanded polystyrene, polypropylene fiber, 2%HBCD dosage) (reference dosage 2%HBCD, 1% XPS, two antimony oxide three) and other styrene resin, showing more its excellent performance, also can be used for flame retardant additives HIPS, PP, cable materials, polyester, acrylic, polypropylene, polycarbonate and other polyolefin plastics, is also suitable for textile, coatings, adhesives, SBR, epoxy resin and unsaturated polyester resin for flame retardant.


Packing：
The standard package is a 25 kilogram paper plastic composite bag, or is packaged according to the requirements of the user.


Matters needing attention：
The product has microstimulated, avoid breathing when in use.
