Lubrizol ESTANE® TPU

Lubrizol invented thermoplastic polyurethane in 1959.For over 30 years, their ESTANE® aliphatic grades have been the benchmark polymer for premium PPF: used by the industry's best-performing films worldwide.

Founded 1959 · Berkshire Hathaway subsidiary
World's oldest and largest TPU manufacturer

Aliphatic TPU Chemistry

Not all TPU is the same.Cheaper films use aromatic TPU - it costs less but turns yellow under UV within one to two years. Lubrizol's aliphatic grades are inherently UV-stable, staying crystal clear for the lifetime of the film.
