KMT Industrial

What KMT Industrial does

KMT Industrial (HK) Ltd, founded in 2008 and headquartered in Hong Kong with primary operations in Lanzhou, Gansu Province (administrative and R&D), Dingxi (manufacturing), and Dandong, Liaoning (manufacturing), manufactures magnesium hydroxide and related flame retardant mineral compounds for industrial B2B customers. Its product portfolio spans seven core lines: hexagonal magnesium hydroxide (HP series), ultrafine nano magnesium hydroxide (P1 series), precipitated magnesium hydroxide, AM3V aluminum-magnesium layered double hydroxide (LDH) for antimony trioxide replacement, hydromagnesite (HM series), natural brucite powder (B series), and aluminum hydroxide (A series), plus add-on technical support services covering formulation development, lab trials, and compliance testing. The company holds dozens of patents, most notably proprietary polymer-specific coatings (PM5S series, HM2V, AM3V) and a distinctive three-stage thermal decomposition mechanism for hydromagnesite (water release at ~220°C, CO2 at ~330°C, char formation at ~560°C) that delivers fire retardancy in EVA, PE, PVC, EPDM, and NBR polymer systems.

The company runs a consultative enterprise sales motion targeting compounders and OEMs in wire and cable, building materials (notably B1/A2 grade aluminum composite panels), electronic and electrical, and adjacent plastics and rubber industries. Revenue is generated through one-time purchase orders of flame retardant mineral products priced on a quote basis that varies by volume, purity, and coating specification; all pricing is private and negotiated. Two production plants are ISO9001, ISO14001, and ISO45001 certified, products carry RoHS compliance and EU REACH registration, and combined nameplate capacity exceeds 160,000 tons per year across brucite, hydromagnesite, and aluminum hydroxide. Distribution runs through direct enterprise sales supplemented by a warehouse and agency network in the United States, Germany, Spain, Turkey, and India, supporting exports to more than 30 countries. R&D is anchored at the Lanzhou center with collaborations to Tongji, Xi'an Jiaotong, and Lanzhou Universities.
