Flame Retardants / Fire Retardants for Adhesives and Sealants

Exolit® OP 930 by Clariant is an organic phosphinate-based fine-grained powder. Acts as a flame retardant.

• Non-hygroscopic, insoluble in water, and common organic solvents like acetone, dichloromethane, MEK, and toluene.
• Easily dispersed in solvents like acetone or MEK.
• Non-toxic, halogen-free, and can be readily dispersed in epoxy resin systems when a high shear mixer is used.
• Suitable for use in both thermoplastic and thermoset applications where the most stringent fire retardancy standards must be met.
• Exolit® OP 930 is applicable in epoxy-based laminates for printed circuit boards.

ROFLAM 6 by PCC Rokita is N,N-bis-(2-hydroxyethyl) aminomethane phosphonic acid diethyl ester. Acts as non-halogen reactive flame retardant for rigid polyurethane foams. It is also used for epoxy resins, acrylic resins and phenolics. Suitable for use in adhesives. ROFLAM 6 has a shelf life of 6 months.

ULTEM™ Resin 1000P by SABIC is polyetherimide-based flame retardant. It is a high-performance polymer that combines excellent thermal properties, exceptional dimensional stability and good chemical resistance. It imparts improved dispersion, faster dissolution in standard solvents, low smoke evolution and toxicity. It can accelerate dissolution times by 4-6. It promotes non-halogenated flame retardance and offers stable di-electrical constant and dissipation factors. ULTEM™ Resin 1000P has a high glass transition temperature together with excellent long-term heat resistance.

CHARMAX LS™ ZHS by Polymer Additives Group is zinc hydroxystannate. It is an excellent smoke suppressant designed to meet stringent smoke requirements for a wide variety of applications. It is compatible with flexible & rigid polyvinyl chloride (PVC), nitrile butadiene rubber (NBR) and polyolefins. CHARMAX LS™ ZHS is recommended for use in adhesives.

Polysurf HPL by ADDAPT Chemicals is a solvent- free proprietary mixture of methacrylated mono- and di-phosphate ester. Used as UV-curable additive, polymerizable lipophilic non-ionic surfactant, effective flame retardant and/or effective polymerisable plasticizer. Suitable for polyesters, polyacrylates and polyvinylchlorides. Polysurf HPL is used in adhesives.

Saytex® BT-93 by Albemarle is a ethylenebistetrabromophthalimide that combines stable, aromatic bromine with an imide structure. Used as a flame retardant. Suits with polyolefins, high-impact polystyrene (HIPS), thermoplastic polyesters (PBT, PET,etc.), polycarbonate and elastomers. Saytex® BT-93 possesses outstanding thermal and UV stability.

RP-EP by Guangzhou Yinsu Flame Retardant New Material is a non-halogenated flame-retardant made of stabilized microencapsulated red phosphorus mixed with an epoxy resin carrier. It has thixotropic properties that hinder the settling process and simplify the re-homogenization process after long storage periods. It is used in foam material, adhesives and sealants to improve the flame-retardant properties.

Ammonium Polyphosphate by Guangzhou Yinsu Flame Retardant New Material is a phosphorus nitrogen-based, non-halogen and eco-friendly non-toxic flame retardant. It offers excellent water resistance, aging resistance, and good thermal stability. It has fine particle size, good dispersion, low water insolubility, low fuming and non-hygroscopic. It is suitable for adhesives and sealants. It fully complies with EU RoHS and achieves the UL94-V0 level.

PVC-T4 by Guangzhou Yinsu Flame Retardant New Material is a flame retardant compounded with environmentally friendly antimony trioxide after activation treatment. It is used to completely replace Sb₂O₃, unlike zinc borate, hydroaluminate or other synergists.

• It has high temperature resistance, fine particle size and good dispersion.
• It also reduces the melt droplets when burning.
• It is widely used in adhesive tapes.
• It can reach more than 95% of the whiteness of antimony trioxide.
• Recommended dosage of PVC-T4 is 4% to reach UL94-V0 (2.0mm).

MCA-B by Guangzhou Yinsu Flame Retardant New Material is halogen-free, low-smoke, low-toxicity flame retardant. It shows good compatibility with resins and high flame-retardant efficiency. It disperses easily and evenly in the matrix, avoiding agglomeration. It is used in adhesives. It is used in wires and cables, building materials and automotive interiors.
