Application of lab scale twin screw extruder


Color Masterbatch

Color masterbatch is mainly composed of color pigments, resin, dispersants, and additives. Jinwo lab extruder machine is suitable for Mono color masterbatch and Tailor-Made masterbatch.


Biodegradable Plastic

To protect the environment, biodegradable plastic is an irresistible trend. Jinwo Machinery is specialist for complete extrusion lines for bioplastics, and our laboratory extruders is a nice choice to research degradable material formula.


Engineering Plastic

Engineering plastic is sensitive to overheating and hydrolytic degradation. Our lab plastic compounding extruder line is mainly used for making engineering plastic pellets such as fire resistance, fiberglass, carbon fiber, etc.


Filler Masterbatch

Jinwo lab extrusion line is suitable for various filler masterbatch, which is concentrates of CaCo3 or Talc or BaSo4 in a polymer base. Our laboratory filler masterbatch extruder machine is widely used to R&D to confirm formula and small scale trial production.


TPV Thermoplastic Elastomers

TPV (Thermoplastic Vulcanizate) is made of polymer (PP/PE/PS) and rubber (EPDM, NBR, SEBS, ACM, etc ) with oil, plasticizer, additives, etc. TPV compounding needs a two-step process. And our lab extruder can be used to research formula as well.
