Flame Retardant
Innovation and production
We are leading manufacturers of magnesium hydroxide in China, we are the only one in the world who both have mineral and synthetic product centres.
For more than 35 years we focus on PVC cable, HFFR cable compound, flame retardant panel, aluminium composite panel, flue gas desulfurization, wastewater treatment, magnesium fertilizer, etc. industry.
Product
HP Series:
Hexagonal Magnesium Hydroxide
HP5 is a kind of halogen free environmentally friendly flame retardant Have two types: non-coated and coated with special additives especially designed for HFFR, EVA and other high requirement polyolefin products. KMT Hexagon plate structure provides good fluidity and dispersion. Could achieve high elongation at break. Good charing formation performance. BET controlled Easy dispersing Lower compounding torque Higher compound MFI
PM Series:
Precipitated Magnesium Hydroxide
PM series precipitated magnesium hydroxide are patent product developed recent years. Their performance could compete with high level magnesium hydroxide produced by Austria, Japan, Russia. It could be applied to produce low smoke zero halogen flame retardant cable and wire. Our customers includes world top level cable companies such as Prysmian, Nexans, LS Cable…
HM Series:
Hydromagnesite
Nature’s own fire retardant Hydromagnesite Chemical formula: Mg5(CO3)4(OH)2•4H2O This unique natural minerals is also known as HMH. It is a proven fire retardant filler in a wide range of polymers and rubbers such as EVA, POE, polyethylene (PE), polyvinyl chloride (PVC), ethylene-propylene diene monomer (EPDM) and Nitrile Rubber (NBR). KMT HM products comply with RoHs and Reach requirements
B Series:
Natural Brucite Powder
The production of natural Brucite is started in the year 2000. B series Brucite has both high purity and high whiteness characteristics. We can tailor-made products in different purity, whiteness, particle sizes, and surface treatment based on customer’s requirements. B series Brucite is widely used in PVC cable, HFFR cable compound, flame retardant panel, aluminum composite panel, flue gas desulfurization, wastewater treatment, magnesium fertilizer, etc.
A Series:
Aluminum Hydroxide
Virtually all the aluminum hydroxide used commercially is manufactured by the Bayer process which involves dissolving bauxite in sodium hydroxide at temperatures up to 270 °C (518 °F). The waste solid, bauxite tailings, is removed and aluminum hydroxide is precipitated from the remaining solution of sodium aluminate. Aluminum Hydroxide can be used as a halogen-free flame retardant due to its well-distributed granularity, good stability, non-toxic and non-polluting.

Mechanical properties comparison of different magnesium hydroxide grades in low-smoke halogen-free flame retardant systems
Formulation was: EVA (7470K) 35%, compatibilizer 5%, antioxidant 0.175%, magnesium hydroxide 60%; Test conditions: 23℃, 40%; and we want to compare two grades XK-10000SN/99 and H5IV mechanical properties, finally the test result shows the tensile strength of XK-10000SN/99 is 16.3Mpa, the elongation at break is 190, the melt index is 0.3, and the oxygen index is 33; the tensile strength of H5IV is 14.8Mpa, The elongation at break is 210, the melt index is 0.52, and the oxygen index is 31.5.
