Huafon Group: the group and where its production sits
Huafon Group (华峰集团, 华峰集团有限公司) is a Chinese new-materials group based in Wenzhou, Zhejiang province, founded in 1991. Its production bases are in Zhejiang, Shanghai, Chongqing and Jiangsu; the lines are polyurethane, polyamide, bio-materials, biodegradable plastics and aluminium. Three listed subsidiaries: Huafon Chemical [002064], Huafon Microfibre [300180] and Huafon Aluminium [601702]. Head-office contacts: 0577-65178888, website huafeng.com, English version en.huafeng.com. The group runs no machinery business of its own: below are its production lines and the equipment applied in them.
What to clarify: the line, the product and the task
Polyurethane systems and polyester polyol production
Polyurethane systems and polyester polyols are the group's core line, run by 浙江华峰新材料有限公司 with sites in Ruian (Zhejiang) and Chongqing. The process is built on polyester polyol synthesis and polyurethane system compounding: synthesis vessels and reaction tanks, component metering and mixing units, temperature control, filtration and filling. Confirmed applications of the output are footwear, composites (solar-frame and window/door profiles), railway pads and 3D printing. The line sets its own grades and formulations; the group publishes no equipment makes.
PU resins are made by 浙江华峰合成树脂有限公司, a group company founded in March 2008 with bases in Zhejiang and Guangdong. Confirmed series: leather, bio, adhesive, waterborne, blocked solvent-free and AB solvent-free. Waterborne and solvent-free series need a different equipment scheme from solvent-borne ones: synthesis reactors, dispersion, vacuum stripping, filtration and metered filling. The line's brand is 华峰. The group discloses no reactor or disperser makes.
TPU is made by 浙江华峰热塑性聚氨酯有限公司, a group company founded in August 2008. Production is built on automated casting and extrusion followed by pelletising; the group does not disclose the exact process. The material is used in consumer goods, medical devices, electronics and automotive, and is supplied as pellets and film. The new-product line includes an aliphatic TPU under the huafon® mark as film for automotive trim. For an enquiry, the grade, hardness, colour and processing route matter.
Spandex is the line of 华峰化学股份有限公司 (Huafon Chemical, 002064); the yarn brand is 千禧 with a linear density range of 10D–2500D. Production is yarn spinning, with sites in Zhejiang and Chongqing (Fuling). Series: high-performance, differentiated, eco and medical-grade; yarn types include black, highly chlorine-resistant, antibacterial, antibacterial-deodorant, dyeable, bio-spandex, recycled and diaper spandex. A solvent-free spandex is presented separately in the group's new products. The group publishes no spinning equipment makes.
What to clarify: linear density, yarn type and volume
Microfibre is made by 上海华峰超纤科技股份有限公司 (300180); the sites are Shanghai (Jinshan) and Jiangsu (Qidong). The full cycle is confirmed: in-house PU resin production, blend spinning, nonwoven web forming, PU impregnation, fibre washing (开纤), dry coating and finishing. Material brands are Aumira®, Toccare®, Antelope®, MFL®-nature and reGen®, plus CHICLING®, Laedana® and Nuprima®. The output is pile and composite materials in rolls; the group discloses no line makes.
Aluminium rolling and processing for heat transfer
Aluminium heat-transfer materials are made by 上海华峰铝业股份有限公司 (601702); the sites are Shanghai (Jinshan) and Chongqing (Fuling). The process is multilayer composite rolling: sheet, strip and foil from 0.008 to 4.0 mm thick with yield strength of 20–200+ MPa. Confirmed applications: engine thermal management, air conditioning, the "three electrics", energy storage, wind power, construction machinery, data centres and 5G base stations; battery housings, battery foil, aluminium-plastic film, brazed honeycomb panels and heat shields. For the CTB water-cooling plate with preflux, 6xxx-series aluminium in a sandwich structure, powder metallurgy and multilayer rolling are confirmed.
What to clarify: thickness, width and joining method
The group's polyamide chain is in Chongqing (Baitao): benzene → adipic acid → adiponitrile (ADN) → hexamethylenediamine (HMD) → nylon 66. The group mastered ADN production from adipic acid in 2019. Adipic acid is made by 重庆华峰化工有限公司, ADN and HMD by 重庆华峰材料科技集团有限公司; cyclopentanone and ACCP are named as by-products. Cyclohexanone is obtained by hydrating cyclohexene and then dehydrogenating cyclohexanol. The process loops are confirmed by the official line descriptions; the group publishes no unit makes.
Nylon 66 is polymerised in Ruian (华峰集团有限公司聚酰胺瑞安分公司) and at the group's Chongqing site. Confirmed steps in the line's development: batch polymerisation from May 2011, a continuous line from May 2015 and then the Chongqing site. Processing grades: engineering grades EP158, EP1107, EP1106, EP158NH, EP126NH; injection grades EP158L, EP626F, EP127HL; spinning grades T25HL, T32HL, T25LD, T25SD, T25FD, T27, T31, T37, T42, T51. For high-speed spinning the group introduces the pernnova™ brand with grades T25LD, T25SD and T25FD.
Biodegradable resins are made by 华峰集团有限公司瑞安环保材料分公司 in Binhai park, Ruian. PBAT runs on a two-stage process; the manufacturer states heat resistance up to 230 °C. PPC is a CO₂-based polymer: according to the group, the bound-CO₂ share exceeds 40 %. Both are supplied as resin and processed on the customer's equipment — extrusion, film, foaming. The group discloses no equipment makes or line composition.
The group's bio line is run by 上海/浙江/江苏华峰瑞讯生物材料有限公司. A bio-PTT polymerisation plant operates in Binhai park, Ruian: the feedstock and technology were acquired from DuPont and the material is sold under the SORONA® mark. The bio series also includes bio-PTMEG CovationBio® and bio-PDO from biomass. A non-food bio-feedstock project is announced separately. The polymerisation plant is a confirmed element of the production; the group publishes no equipment makes.
Automated hydraulic moulding is a confirmed process in the group's polyurethane systems line. Transparent PU for footwear is produced under the Linxfon® mark; in this process the sole thickness is 0.3–1.5 mm. Moulding runs on hydraulic equipment with an automated cycle and the formulation is supplied as a system; the group discloses no press or mould makes. For an enquiry, part thickness, transparency, cycle time and mould requirements matter.
