Extrusion molding. this process is used in polymer processing very often, and in typical extrusion processes pellets are put into one end of a machine to melt and blend them into a gel. then, the material is pushed through a die head, from which it emerges in the shape of the desired material.
Tpu is a block copolymer consisting of alternating sequences of hard and soft segments or domains formed by the reaction of: (1) diisocyanates with short-chain diols (so-called chain extenders) and (2) diisocyanates with long-chain diols. by varying the ratio, structure and/or molecular weight of the reaction compounds, an enormous variety of different tpu can be produced.
Pu definition: pu polyurethane is a polymer material, polyurethane called polyurethanes, is the main chain containing repeating carbamate group of macromolecular compounds collectively. it is made from organic diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compound. pu classification: thermosetting and thermoplastic.
