WebTherefore, by using high-melting-point polymer crystals as NAs, the crystallization rate of their low-melting-point polymer matrix can be improved largely, thus providing a simple way to obtain high crystallinity products for semicrystalline … WebDo thermosetting polymers have a high melting point? The cross-linking forms a molecule with a larger molecular weight, resulting in a material with a higher melting point. During the reaction, the polymer's molecular weight increases to the point that its melting point is higher than the surrounding ambient temperature.
WebNov 12, 2024 · It is a rigid and opaque polymer with a high melting point (280°C). In terms of properties, it can hold its own against PTFE, PEEK and even PI (Polyimide). Cost-wise, it rests somewhere in between PTFE and PEEK, making it a good balance between the two. PPS offers an excellent balance of properties such as: http://lookpolymers.com/findproperty.php?pid=3&sx_id=15&value=32.0&type=3
