Thermoplastic polyurethanes derived from petrochemical or renewable resources: A comprehensive review

Biodegradable thermoplastic polyurethanes incorporating polyhedral oligosilsesquioxane.

A new hybrid thermoplastic polyurethane (TPU) system that incorporates an organic, biodegradable poly(D, L-lactide) soft block with a hard block bearing the inorganic polyhedral oligosilsesquioxane (POSS) moiety is introduced and studied. Changes in the polyol composition made through variation of the hydrophilic initiator molecular weight show direct control of the final transition temperature...

Novel Polybutadiene Diols for Thermoplastic Polyurethanes

Krasol® polybutadiene diols are anionically polymerized products characterized by very narrow molecular weight distribution, linear structure of polymer chains and the absence of species with functionality higher than 0.2. These unique features make them suitable as hydrophobic polyol components for use in thermoplastic polyurethanes (TPUs). Various TPU formulations were developed using polybut...

Highly Resilient Non-Soften Thermoplastic Polyurethanes

Thermoplastic polyurethanes (TPUs) are a class of thermoplastic elastomers (TPEs) that are used in a variety of applications (1). TPUs exhibit low temperature flexibility, excellent abrasion resistance, high tensile strength and good processing characteristics. The current medical grade TPU’s have unique property that the flex modulus decreases (softens) when placed in the body. A new resilient...

Antimicrobial Peptides Derived from Milk: A Review

Milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. The release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. Peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...
