Processes of thermoforming and blow molding are inflation of plastics sheets, mechanics of the processes involves large deformations of a hotpolymer membrane.
热成型和中空成型过程实质上是热塑料膜的膨胀过程，它们都涉及到材料的大变形。

He created this composite by growing a forest of nanotubes using hot hydrocarbon gases and an iron catalyst, and then filling the space between the tubes with the polymer.
A hot research spot of polymer material auxiliary reagent is flame retardant. And the environmental safety of flame retardants is of more and more importance.
