Product Description

Lubrizol TPU – Thermoplastic Polyurethane

The Lubrizol Corporation, formerly BF Goodrich, began developing synthetic rubber compounding technologies in the 1950s and is recognized as one of the earliest pioneers in the research, development, and commercialization of TPU (Thermoplastic Polyurethane). In 2008, Lubrizol further strengthened its global leadership by acquiring the TPU businesses of Dow Chemical and SK Chemicals, making it one of the world’s largest TPU producers today.

Lubrizol is also the only global manufacturer offering UL-certified flame-retardant TPU grades, demonstrating outstanding reliability in material safety, stability, and quality control. Its TPU materials are widely trusted and adopted across automotive, electronics, medical, and textile industries.

TPU (Thermoplastic Polyurethane) is an engineering elastomer that combines high tensile strength with excellent flexibility, featuring:

  • Good water resistance and oxygen permeability

  • Excellent adhesion, resistant to delamination

  • Polyester and polyether grades with biodegradability over decades when buried in soil

  • Widely used in Europe and the U.S. as a replacement for PVC, especially in textile lamination and garment applications

Key Features

  • Excellent abrasion resistance

  • High toughness, strength, and tensile performance

  • Superior fatigue resistance for repeated flexing

  • Good oil resistance

  • Rubber-like elasticity and resilience

  • No plasticizers required (environmentally friendly)

  • Excellent low-temperature flexibility

  • Non-toxic and eco-friendly; suitable for medical and baby products

  • Wide hardness range; low-hardness grades approach vulcanized rubber in tensile strength

  • Versatile processing: injection molding, extrusion, film blowing, calendering

Main Applications

  • Textile & garment lamination (functional fabrics, waterproof jackets, sportswear)

  • Footwear components (outsoles, midsoles, support structures)

  • Packaging materials (biodegradable films)

  • Electronic accessories (phone cases, cable jackets)

  • Medical products (tubing, elastic bandages)

  • Automotive parts (seals, hoses, interior trims)

  • Children’s products (non-toxic toys, protective mats)

  • Industrial components (mechanical parts, belts)

Estane® Series

Grade: 2355
