Foaming Materials Flame Retardant Solutions

We have an excellent technical team, which can be designed according to customers requirements.

We deploy advanced formulation expertise to solve the critical challenge: balancing flame safety with cellular integrity. In insulation panels, protective packaging, and lightweight automotive components, foams must resist ignition while maintaining essential properties like density, compression set, and thermal stability. YINSU delivers precision-engineered solutions for polyurethane (PU), polystyrene (PS), polyethylene (PE), and specialty foams that meet stringent UL94 HF-1, FMVSS 302, and EN 13501-1 standards without compromising structural performance.


Critical Performance Safeguards

Foamed materials demand specialized FR approaches to address:

  • Cell structure preservation – Preventing collapse during FR incorporation

  • Smoke density control – Critical for enclosed spaces (building cavities, vehicle interiors)

  • Thermal stability – Maintaining integrity at service temperatures (-40°C to +150°C)

  • Hydrolysis resistance – For humid environments (HVAC, refrigeration systems)


Your Partner in Cellular Safety

From construction insulation and EV battery padding to aerospace acoustic panels and protective packaging – YINSU tailors solutions that protect both product integrity and end-users. We engineer flame retardancy that moves with your material.
