Flame Retardants

Ascent Chemicals manufactures the PyrGuard line of phosphorus-based flame retardants, including organophosphate esters and diammonium phosphate solutions. Our product portfolio includes PyrGuard 62 (phosphate ester blend for coatings and latex), PyrGuard 66 (durable flame retardant for polyester fabrics), PyrGuard KK (polymeric phosphate ester for textiles), PyrGuard 102-52A (phosphate ester polymer for cotton and rayon fabrics), and PyrGuard DAP (diammonium phosphate solution for drapery and upholstery).

Yes, PyrGuard flame retardants are phosphorus-based and designed as safer, eco-conscious alternatives to traditional brominated and chlorinated (halogenated) compounds. They address fire safety challenges without the environmental and health concerns associated with halogenated flame retardants.

Ascent Chemicals supplies flame retardants to multiple industries including textiles and apparel, automotive and transportation, furniture and upholstery, construction, electronics, coatings and adhesives (CASE), pulp and paper, and decorative fabrics manufacturing.

PyrGuard 66 and PyrGuard DAP are specifically engineered for polyester fabrics. PyrGuard 66 is a durable flame retardant ideal for drapery, upholstery, and automotive textiles on 100% polyester, while also providing flame resistance on nylon and polypropylene blends. Both products help fabrics meet NFPA 701 small-scale flammability requirements.

PyrGuard 102-52A is specifically designed for cotton and rayon fabrics, including those with synthetic fibers like polyester. It provides a semi-durable, non-rusting flame retardant finish that is durable to dry cleaning and suitable for drapery and decorative fabrics.

Yes, PyrGuard 62 is a highly concentrated dispersion of water-insoluble fire retardants specifically formulated for latex, paints, coatings, and paper finishing applications. It features high activity, small particle size, and does not affect substrate color.

PyrGuard flame retardants are typically clear to opaque liquids with neutral pH (7.6-10.0), water solubility, and solids content ranging from 36-64% depending on the product. They are nontoxic, non-hygroscopic, rust-inhibiting, and do not cause color change with most dyestuffs.

Yes, PyrGuard 66 and PyrGuard DAP help fabrics meet NFPA 701 small-scale flammability requirements when used with flame-retardant back coatings, making them ideal for commercial, residential, and transportation applications.

Ascent Chemicals manufactures flame retardants at three U.S. facilities located in Fountain Inn, South Carolina; Cleveland, Tennessee; and Danville, Virginia. This domestic manufacturing ensures reliable supply, quality control, and responsive customer service.

Both are semi-durable organic flame retardants for textiles, but PyrGuard KK (CAS# 94031-26-2) is a polymeric phosphate ester for general fabric and fiber processing, while PyrGuard 102-52A is a phosphate ester polymer specifically designed for cotton, rayon, and cotton/polyester blends requiring topical flame-retardant finishes durable to dry cleaning.

Yes, several PyrGuard products work on blended fabrics. PyrGuard 66 and PyrGuard DAP are effective on polyester blends including nylon and polypropylene. PyrGuard 102-52A is suitable for cotton/polyester blends and fabrics with synthetic fibers present.

 Yes, PyrGuard flame retardants are designed with safety in mind. They are nontoxic, odorless, non-fuming, and formulated as safer alternatives to halogenated compounds. PyrGuard 62 specifically uses safe ingredients and is designed as an effective replacement for brominated and chlorinated compounds.
