A general-purpose linear elastomer, specially formulated for Lisa and Lisa Pro.

Linear thermoplastic urethane elastomers, or TPE-U/TPU, are block copolymers of polyols and diisocyanates pioneered by BF Goodrich in the late 1950s. Their varying polymer ratios yield materials ranging from semi-rigid to highly elastic, finding use in various industries and applications cable coatings, hose manufacturing, textiles, shoe soles, waterproofing, vibration dampening, and consumer product components.

Urethane-based elastomers stand out for their high resistance to wear and abrasion, high tensile strength, good damping capacity, good toughness and resistance to fats and oils. In addition, TPU is compatible with the skin and has a high resistance to fungi, which makes it suitable even for medical or orthopedic applications.
