Plastics Sector
Flame retardants are essential additives for plastic modification, compatible with various types of plastic substrates:
Electronics and Electrical Appliances: Used in printed circuit boards (PCBs), connector housings, and wire/cable sheathing. Adding 8%–12% phosphate-based flame retardants can raise the Limiting Oxygen Index (LOI) of polycarbonate materials from 22% to over 32%, significantly reducing the risk of fires caused by electrical short circuits.
Engineering Plastics: Incorporating 10%–15% phosphate-based flame retardants into engineering plastics such as PA (polyamide) and PBT (polybutylene terephthalate) enables 1.6mm-thick materials to pass the UL94 V-0 vertical burning test while retaining over 80% of their tensile strength.
New Energy Sector: Used in lithium battery pack housings, insulation materials for charging piles, and automotive wiring harness sheaths, meeting specialized flame-retardant requirements for high-temperature resistance, aging resistance, and resistance to electrolyte corrosion.
Construction Materials Sector
Flame retardants are critical additives for fire safety in construction, applicable to a wide range of building materials:
Thermal Insulation Materials: Adding 12% nanocomposite polyurethane flame retardants to rigid polyurethane foam insulation boards allows the product to meet the Class B1 flame-retardant requirements of the GB 8624-2012 standard. This balances thermal insulation performance with fire resistance, potentially reducing the incidence of fire accidents by 90% in practical applications.
Basic Building Materials: Used for the flame-retardant treatment of PVC pipes, fire doors, flooring, and wall panels. Sulfonate-based flame retardants can block oxygen and promote surface charring during combustion, providing durable fire protection.
Fire-Resistant Coatings: Fire-resistant coatings containing intumescent flame retardants are used on building facades and steel structures. Upon exposure to fire, they rapidly form a protective layer that inhibits the spread of flames and smoke, thereby enhancing the building's overall fire safety rating.
