#CMT# #/CMT# Thermoplastic shaping involves accomplishing shaping at 150-240[deg] C in absence of extrusion additive, softeners, glycerin, starch, polyolefins, polypropylene, polymethylmetacrylate, polyvinylacetate, polyethylene glycols or thermoplastic polymers. The polyvinyl alcohol contains 5 wt.% of a volatile compound. The thermoplastic shaping takes place by extruding or injection molding. 0 to 0.5 wt.% of methanol content is present in polyvinyl alcohol after the thermoplastic shaping. #CMT#USE : #/CMT# Method for thermoplastic shaping of polyvinyl alcohol for manufacturing granulates, foil, fibers, two or three-dimensional injection mold bodies or coating for use in pharmaceutical or cosmetic applications (all claimed). #CMT#ADVANTAGE : #/CMT# The thermoplastic shaping method ensures that the polyvinyl alcohol is processed in pure form, without extrusion additive. #CMT#EXAMPLE : #/CMT# No suitable example given. |
