tpu 2 series-手机版捕鱼


thermoplastic polyurethane elastomer (tpu) is a linear polymer obtained by addition polymerization of long chain diol, diisocyanate and small molecule diol/amine chain extender. long chain diol forms soft segment, small molecule chain extender and diisocyanate form hard segment to form microphase separation structure, which makes it have good physical properties. by adjusting the ratio between the soft and hard segments, products with shore hardness in the range of 50a-85d can be obtained.

the physical properties and good processability of tpu make it widely used in common fields such as pipes, cables, leather, films, hot melt adhesives, etc. common processing methods of thermoplastic materials, such as extrusion, injection molding, blow molding, calendaring, tape casting, etc., tpu materials can be applied; however, due to its solvent-free and recyclable processing characteristics, it is increasingly widely used in today's increasingly stringent environmental requirements.
