Polymer high melting point
There are many synonyms for the term high-performance plastics, such as: high temperature plastics, high-performance polymers, high performance thermoplastics or high-tech plastics. ... This is because semi-crystalline polymers have, in addition to a glass temperature T g, a crystallite melting point T m, which is … See more High-performance plastics are plastics that meet higher requirements than standard or engineering plastics. They are more expensive and used in smaller amounts. See more High performance plastics differ from standard plastics and engineering plastics primarily by their temperature stability, but also by their chemical resistance and mechanical properties, … See more High performance plastics meet higher requirements than standard and engineering plastics because of their more desirable mechanical properties, higher chemical and/or a … See more The improvement of mechanical properties and thermal stability is and has always been an important goal in the research of … See more • Commodity plastics • Engineering plastic See more WebNov 1, 2015 · Facing the problem of the high melting point PA6, which is difficult to blend with the lower processing temperature polymers [8–13], we prepared LPA6 with a melting point of 198°C through melt extrusion to afford production on a large-scale. This procedure finally permitted blending of PA6 with the lower processing temperature polymers [14].
