• Polyurethane foams (insulation, furniture)
• PVC and epoxy resins (flooring, pipes, coatings)
• Textiles and wall coverings
• Wood coatings and sealants
• Thermoplastic composites used in ceilings and panels

Performance Goals:

• Achieve UL-94 V0 or EN13501 flammability ratings.
• বজাই ৰাখক mechanical integrity and color stability.
• Meet low-smoke, halogen-free regulations.
