Flame retardants
Traditional flame retardants rely on toxic chemicals that pose risks to human health, hinder recyclability, and harm the environment. D-PYRE® is Bioenvision’s non-toxic, halogen-free flame retardant synergist - designed to deliver high performance without harmful trade-offs.
Compatible with plastics, coatings, and composite materials, D-PYRE® supports both safety and sustainability. D-PYRE® enables cleaner chemistry and a smarter path forward in flame-retardant innovation.
D-PYRE® - The non-toxic flame retardant
The development of D-PYRE® is the result of over 15 years of dedicated research, driven by our R&D team’s commitment to advancing its technology.
D-PYRE® has a wide range of application areas, including:
Construction materials (wall sheeting, roofing, insulation foam, and flooring)
Electrical and electronic products
Transportation products (seats, bumpers, parts of automotives/airplanes)
Textile and furniture products
This broad spectrum of applications underscores the significance of D-PYRE® as a world-class green flame retardant.
D-PYRE® Benefits
Environmentally friendly
D-PYRE® represents a groundbreaking, non-toxic and environmentally friendly flame retardant based on POSS (Polyhedral Oligomeric Silsesquioxane) technology.
Recyclable
Incorporating D-PYRE® into materials such as cables, artificial leather, roofing, flooring, technical textiles, and general PVC compounds enhances recyclability, enhancing sustainability and circularity.
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, offering the potential for cost savings and profitable advantages when compared to traditional flame retardants.
