A thermoplastic polyurethane composite material composition includes a plastic base material and a curing agent, the plastic base material includes a thermoplastic polyurethane and a silicone gum including at least two alkenyl groups in each of molecules thereof, wherein the thermoplastic polyurethane and the silicone gum are uniformly mixed, and a weight ratio of the thermoplastic polyurethane and the silicone gum is ranging from 95.01:4.99 to 99.5:0.5. The curing agent is uniformly mixed with the plastic base material, wherein the curing agent has an adding amount enabling the silicone gum to crosslink to form a silicone rubber.

Described herein is a polyurethane foam prepared with certain polytetrahydrofurans and optional polyether polyols. The polyurethane foam is characterized by low hardness increase at low temperature as compared with conventional polyurethane foam, and is suitable for use in products which can be exposed to low temperature such as snow boots.

A sole and a manufacturing method of a polymer material are provided. The manufacturing method of a polymer material includes: providing a shoe; performing an alcoholysis reaction of the shoe with a diol to form a polyester oligomer; and performing a polymerization reaction of the polyester oligomer and a polyalkylene glycol to obtain a thermoplastic polyester elastomer. The shoe includes a midsole, an outsole, an upper, a tongue, an insole and an adhesive. A material of the midsole, the outsole, the upper, the tongue, the insole and the adhesive are a polyester material.

A polyurethane foam is disclosed having unique load bearing characteristics rendering it suitable for a variety of applications. The foam exhibits high surface-softness and smoothness properties, making it well-suited for use in articles such as pillows and mattress toppers. However, upon continued application of pressure, the resilience of the foam increases sharply, translating into a remarkable support characteristics that make the foam suitable for use in the seat portions of chairs and sofas, as well as in the base portion of mattresses. The foams therefore address the limitations of conventional, high-resilience and visco-elastic polyurethane foams. A process of making the foam and its use in various articles is also disclosed.

The invention relates to an article made from a thermoplastic polyurethane composition having that has high flex modulus, low density, and is capable of withstanding repeated cyclic deformation. The thermoplastic polyurethane composition is formed from the reaction product of a polyol component, which includes a blend of a polyether polyol, such as poly(tetramethylene ether glycol), and polybutadiene diol, a diisocyanate component, and a chain extender component.

The present disclosure relates to gel compositions of, or containing, a non-isocyanate polyurethane (NIPU) elastomer formed from the reaction of a polycarbonate, where carbonate groups may be cyclic or non-cyclic, and a polyamine, where amines are either primary or secondary, in an optional topically acceptable carrier fluid. The gelled compositions may further contain a personal or healthcare active. The actives may be incorporated into the gel via either a pre or post load method.

Foamed pellets contain a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition (IC), containing at least one aliphatic diisocyanate having a number-average molecular weight of less than 200 g/mol, at least one chain extender (CE1), and a polyol composition (PC). A process can be used for the production of such foamed pellets. The foamed pellets can be used for the production of a molded body.

Improved soles and insoles for shoes, in particular sports shoes, are described. In an aspect, a sole for a shoe, in particular a sports shoe, with at least a first and a second surface region is provided. The first surface region comprises expanded thermoplastic polyurethane (TPU). The second surface region is free from expanded TPU.
