Thermoplastic polyurethane elastomers (TPU/TPE-U) TPUs are block copolymers with urethane backbone linkages. They have two types of blocks: Hard segment— It is formed by the addition of a chain extender to a diisocyanate. For example, diisocyanates, short-chain diols (commonly used are 1,4...
Looking into urethane vs. polyurethane for your material needs? These materials are closely related but offer different properties and performance characteristics in molding applications. While urethane refers to a specific molecular structure, polyurethane is the polymer formed by combining multiple urethan...
TPE vs. Silicone Rubber (Thermoset) Materials Thermoplastic elastomers (TPEs) differ from thermoset elastomers in the way their molecules attach to each other. Another difference is that TPEs can be processed on conventional injection molding machines. The resin is heated beyond its melting point, mo...
Various types of thermosetting polymers contribute to the expansive landscape of possibilities. Melamine, epoxy, polyester, silicone, urea-formaldehyde, polyurethane, polytetrafluoroethylene (PTFE), and polyvinylidene fluoride (PVDF) represent a spectrum of producable thermoset choices, each with its own ...

The thermoplastic flexible composition consists of thermoplastic polyurethane and partly crosslinked graft rubbers based on an acrylate rubber with a core/shell structure and/or a silicone rubber. The partly crosslinked graft rubber has a rubber content of 40-85 weight percent and contains a grafted ...
Alternatively, polymeric materials useful as article 14 include PTFE or ePTFE, polyethylene terephthalate (PET), polydimethylsiloxane (silicone), polyurethane (PU), or various other polymers known for use as medical devices. While the figure indicates that the entire outer surface of article 14 is ...
