Is the plastic crystalline polymer?
The first floor is the solution
Common non-crystalline plastic are: ABS, AS, PS, PC, etc., the characteristics are no significant melting point; solid molecules were irregular arrangement, strength, tension are weak; melting than the volume is not large, after melting , Curing is relatively easy to shrink ... ...
Common crystalline plastic are: PE, PP, nylon, POM, etc., the characteristics of a significant melting point; solid when the molecules were regularly arranged, strong, strong pull; melting than the volume change, the density after melting low , Easier to shrink after curing ... ...
Plastic according to its polymer structure is divided into crystalline plastic and non-crystalline plastic (amorphous plastic).
