Hongtaiji provides industry flame retardant solutions for you
Customize flame retardant material solutions according to customer needs, meeting strict standards for material performance, cost and efficiency
Engineering Plastics Industry
Engineering plastics have high processing temperatures, requiring extremely strict thermal stability for flame retardants. Hongtaiji solutions effectively address pain points such as decreased mechanical properties, blooming/whitening, and mold corrosion after adding flame retardants, meet strict safety standards for electronic and automotive components, and also provide cost-reducing alternative solutions for antimony trioxide.
View detailsCables and heat shrink tubing
The cable industry faces strict fire tests such as VW-1. Our halogen-free flame retardant materials have excellent extrusion processability and non-dripping characteristics, ensuring high flame retardancy while maximally guaranteeing the cable's high insulation, anti-aging, and tensile resistance and other physical mechanical properties.
View detailsSilicone rubber materials
Silicone rubber molding is easily affected by additives leading to poor vulcanization. Hongtaiji's customized formula completely solves the dispersion problem of flame retardants in elastic systems, prevents later blooming and exudation, and perfectly maintains the material's original high elasticity, weather resistance, and insulation properties.
View detailsInks, coatings, and adhesives
The coating and adhesive systems require extremely high transparency and adhesion. We offer highly compatible flame retardant formulations that ensure no damage to the resin's original film-forming properties, gloss, and bonding strength, with perfect compatibility with water-based and oil-based systems, meeting export environmental compliance requirements.
View detailsPaper & Wood Industry
Porous and flammable materials such as wood and paper pose significant fire hazards. Our flame retardant treatment liquid exhibits excellent penetration and anti-leaching properties, achieving efficient smoke suppression and flame retardant protection without altering the original natural texture and color of the substrate.
View detailsFlame Retardant Tape
Electronic insulating tape is used in confined spaces, demanding extremely high flame retardant efficiency. Hongtai Ji customizes exclusive flame retardants that significantly enhance the overall flame retardant rating of the tape, without sacrificing initial adhesion, holding power, or its critical electrical insulation performance.
View detailsTextile & Leather
Textile coatings and leather protection require stringent environmental and non-toxic standards. Our flame retardant solutions meet halogen-free and low-smoke requirements, with finished products resistant to washing and unaffected softness, widely applicable in protective clothing, home textiles, automotive interiors, and special military applications.
