Recently, Covation Biomaterials LLC (Shanghai Huafon Ruixun Biomaterials Co., Ltd., referred to as CovationBio), a wholly-owned subsidiary of Huafon Group, has officially launched Sorona elasterell-p fiber.Marking the company’s first bicomponent biobased elastic fiber produced onshore in the United States, the product is made from partially biobased Sorona polymer. It delivers consistent elasticity and long-lasting shape retention to fabrics without blending with spandex. Fabrics made with this fiber resist sagging and deformation even after repeated wear and washing cycles.Targeted primarily at activewear and workwear textiles, the new fiber addresses market demand for high-resilience and highly durable fabrics. Thanks to its biobased composition, it also enables apparel brands to cut the carbon footprint of their end products.Sorona polymer boasts a 25-year commercial track record. Containing 37% biobased content, it features softness, skin-friendliness, breathability and wrinkle resistance. It can be easily blended with natural fibers including cotton, wool and linen, and has wide applications across apparel and home textiles.Steven Ackerman, CEO of CovationBio, commented that as the company’s first proprietary branded fiber product, the new offering combines the high-performance and sustainable merits of Sorona material with much-sought elastic textile solutions, further expanding the portfolio of biobased raw materials for the textile industry.Established in Newark, Delaware in 2022, CovationBio manages the existing Sorona product lineup while advancing new material research and development. The firm plans to commercially launch Xatryx biobased polytetramethylene ether glycol (bioPTMEG), an all-new biobased material, in 2026. Mobile: +8615365186327E-mail: sales3@ascent-chem.comWebsite: www.huafon-group.com

Reactive polyurethane hot melt adhesive, commonly abbreviated as PUR within the industry, is chemically a moisture-curable isocyanate-terminated polyurethane prepolymer. It achieves full bonding via initial adhesion formed by physical cooling followed by chemical crosslinking triggered by moisture, which differentiates it from conventional EVA hot melt adhesives that rely merely on physical fusion for bonding. As a core polyurethane material production arm under Huafon Group, Zhejiang Huafon Synthetic Resin Co., Ltd. leverages the group’s complete polyurethane industrial chain to realize stable mass production of PUR hot melt adhesive series, supplying bonding solutions for a wide range of industrial sectors.In terms of curing mechanism, PUR exists as a solid at ambient temperature. When heated to a suitable temperature, it melts into a flowable state. After coating and laminating substrates, rapid initial tack develops during the cooling phase, satisfying the requirement for fast positioning on automated production lines. Unreacted isocyanate groups inside the adhesive layer continuously react with moisture present in the air and substrate pores to gradually build a three-dimensional crosslinked network. The full curing cycle generally lasts 24 to 72 hours. Once fully cured, the bonded structure becomes irreversible and will not melt or delaminate upon reheating.This type of product boasts 100% solid content without added organic solvents. Compared with solvent-based adhesives, it generates lower VOC emissions during production and complies with environmental control standards applicable to most industries. The melting temperature for construction is normally maintained between 110°C and 140°C. Its moderate thermal load allows bonding of certain heat-sensitive plastics, films, textile fabrics and other substrates. After thorough curing, the adhesive layer balances strength and toughness, and delivers outstanding resistance to hydrolysis, extreme temperatures and chemical media. It exhibits reliable adhesion to porous and non-porous materials including timber, metals, various plastics, leather and fabrics.Zhejiang Huafon Synthetic Resin Co., Ltd. has developed multiple specialized grades of PUR hot melt adhesives with customized formulations tailored to distinct application scenarios. The product portfolio covers mainstream application areas such as edge banding and flat lamination of furniture panels, composite bonding of automotive interior components, lamination of functional textile fabrics, and packaging material lamination. Supported by its in-house polyurethane research and development platform, the company can adjust formulations according to customer requirements such as production line cycle, open time, temperature resistance standards and substrate types, enabling stable operation with automated adhesive coating equipment.When deployed in practical manufacturing, PUR hot melt adhesives carry certain constraints for usage. The product is sensitive to moisture, so tight moisture-proof sealing must be implemented throughout storage, melting and coating processes, and dedicated hermetic melting equipment is mandatory. Its overall material cost exceeds that of traditional EVA hot melt adhesives, which means higher upfront equipment investment for enterprises. Customers need to conduct comprehensive evaluation covering substrate types, production line automation level, long-term service environment of finished products and environmental standards during product selection.Driven by continuous upgrading in the home furnishing, automotive and high-end textile industries, the market sets increasingly stringent requirements on the durability and environmental performance of adhesives, which keeps expanding the application landscape of reactive polyurethane hot melt adhesives. Drawing on accumulated expertise in polyurethane resin synthesis, Zhejiang Huafon Synthetic Resin Co., Ltd. keeps optimizing its PUR product lineup to strike a balance between processing workability and long-term durability of finished bonds, providing downstream manufacturing industries with stable and traceable adhesive raw material options. Mobile: +8615365186327E-mail: sales3@ascent-chem.comWebsite: www.huafon-group.com
