Optical Urethanes

Transparent and strong

Lubrizol’s unique thermoplastic polyurethane (TPU) formulations deliver the benefits you need for all of the transparent products you create. They assure low haze and excellent light transmission for a variety of flat, bent and/or spherical security transparencies and specialty laminations. Interlayers made from our films are specifically developed for use in optical laminations of glass, polycarbonate, acrylic, cellulose acetate butyrate (CAB), PET, or combinations thereof.

Outstanding Benefits 

  • Low haze
  • Excellent light transmission
  • Non and low yellowing options
  • No impurities (polyester-free) to eliminate crazing
  • Offer optimum performance at the working temperature of the laminate itself, typically -40°C to 50°C


  • Glass or glass/PC laminations for delayed-entry windows in stores, banks, kiosks and prisons
  • Aircraft windows and high-end ballistic glazing
