Ultralast™

Ultralast Thermoplastic Urethanes are the newest addition to Chemtura’s Urethane product lines. Ultralast line was developed based on Chemtura’s world-leading low free polyurethane prepolymer technology. Ultralast products are characterized by their excellent physical and dynamic performance and broader processing temperature range compared to current thermoplastic polyurethanes (TPUs). Ultralast TPUs provide wide hardness selection, enhanced tear strength, compression set and excellent chemical resistance. Our Ultralast products can be used in a wide range of markets and applications and our customer-intimate service guarantees outstanding supply and support.

Performance advantages of Ultralast Thermoplastic Urethanes' morphology

Performance advantages of Ultralast Thermoplastic Urethanes' morphology

Ultralast Thermoplastic Urethanes are high performance and versatile for various applications. The PPDI TPUs are designed for the most demanding applications in the field. They offer superior toughness, excellent dynamic properties and can perform consistently at elevated temperatures. The high performance MDI TPUs are resistant to hydrolysis and extremely tough. They are also ideal for use in low temperature applications due to lower glass transition temperature compared to current TPUs.

Processing advantages for injection molding and extrusion

Processing advantages for injection molding and extrusion

Ultralast Thermoplastic Urethanes have 10-50°C lower melting point compared to current TPUs without loss in performance. Ultralast products are more thermally stable and therefore more tolerant to temperature variances. The melt flow index (MFI) can be customized to specific applications and the parts are also easier to de-mold after injection molding.

Ultralast Thermoplastic Urethanes have a large number of potential applications in the industrial markets. Superior load bearing, compression set, abrasion resistance, fatigue and set resistance are key product characteristics that Ultralast products offer.

Ultralast Thermoplastic Urethanes can be used in various mining applications. Abrasion resistance, impact resistance and chemical resistance, are key product characteristics that Ultralast products offer to the mining and quarrying market.

Ultralast Thermoplastic Urethanes can be used in many applications in the oil & gas industry. Good abrasion resistance, cut and tear resistance, chemical resistance, oil resistance and property retention at high temperature and dimensional stability are key product characteristics that Ultralast products offer for the oil & gas market.

Our performance thermoplastic polyurethane materials give strength and durability to high-performance recreational equipment, such as golf balls, in-line skate wheels and roller-coaster wheels. Ultralast Thermoplastic Urethanes deliver high rebound, exceptional cut and tear strength, low heat build-up and excellent abrasion properties.
