D-PYRE® non-toxic flame retardants

D-PYRE® is our non-toxic, halogen-free flame retardant additive - designed to deliver high performance without harmful trade-offs.

Compatible with thermoplastics, adhesives, textiles, electronics, foams and composite materials, D-PYRE® supports both safety and sustainability.

Traditional flame retardants rely on toxic chemicals that pose risks to human health, hinder recyclability, and harm the environment. D-PYRE® enables cleaner chemistry and a smarter path forward in flame-retardant innovation.

D-PYRE® is classified as label-free under the UN’s GHS system and the EU’s CLP regulation and contains NONE of the following chemicals:

  • Halogenated compounds

  • Persistent Organic Pollutants (POPs)

  • Endocrine Disrupting Chemicals

  • Metal compounds

  • Persistent Bioaccumulative Toxic substances (PBTs)

  • Carcinogenic, Mutagenic and Reprotoxic chemicals (CMRs)

D-PYRE® Benefits

Excellent flame-retardant properties

D-PYRE® offers outstanding fire resistance by limiting, slowing and preventing the spread of flames - without releasing toxic smoke or emissions.

Recyclable

D-PYRE® is non-toxic and incorporating it into materials such as cables, artificial leather, roofing, flooring, technical textiles, and general PVC compounds enhances recyclability.

Remove / reduced ATO & ATH

D-PYRE® effectively eliminates or significantly reduces the need for ATO (antimony trioxide) and ATH (alumina trihydrate), two toxic substances commonly used in flame retardants.

Low mix ratio / dosage

D-PYRE® boasts a low mix ratio / dosage (only 1-2% loading needed), offering the potential for cost savings and profitable advantages when compared to traditional flame retardants. It’s also easy to mix and disperse with a wide range of polymers.
