Plastic degradation refers to decomposition. In polymer chemistry, it usually refers to the process of decreasing polymerization degree of polymer molecules under chemical or physical action.
Plastic wood composite material is a new type of environmental protection and energy saving material, which is produced by plastic wood extruder.
In order to reduce the cost of products and obtain additional properties, polyurethane thermoplastic elastomer can be used as a common toughening agent to toughen many kinds of thermoplastic plastics and modified rubber materials.
As an excellent elastomer, the downstream product of TPU is very broad, and it is widely used in the fields of daily necessities, sporting goods, toys, decorative materials, and so on.

Counter-rotating twin-screw extruders are another type of twin-screw extruders, which include two kinds of parallel and conical extruders.
Polypropylene (PP) is a kind of semi-crystalline polymer, which has excellent mechanical properties and has been widely used.
The long fiber has large retention length, which makes PP have better rigidity and creep resistance, higher compressive strength, higher flexural strength, better impact property and higher service temperature.
When the whisker is mixed with PP, it can change the crystallization behavior of PP, and has obvious strengthening effect.
