According to the great demand of reducing processing energy consumption

recycling of waste polymers and using of renewable resources in polymer industry

we have innovatively presented and studied the polymer new processing method and technology based on the volume elongational rheology. The mechanism and structure of vane plasticating and conveying process method based on the volume elongational deformation have been discussed as well as the whole plasticating and conveying process. The technology characteristics and advantages and the blend characteristics of vane extruder are also discussed in this paper from the fields of processing different material systems

especially for the multiphase and multicomponent composite materials

polymer/biomass composites

polymer/inorganic nanoparticles composites

etc. The results show that compared to the conventional screw processing technology

the new technology and equipment shows many outstanding advantages

such as wider adaptability of materials

shorter thermo-mechanical history of the plastics processing

better mixing effects

higher quality of the products

etc.
