Improvements include a reduced overall footprint, faster clamp movement for better dry cycle times and lower energy consumption, and lower platen stress and increased mold force stability to reduce mold wear.
Demand remained robust at the start of the month, particularly from the reseller community as sentiment has turned moderately bullish. Processors were also back in the market, unafraid to pay a penny more than in the previous week.
Classroom discussions addressing such topics as co-rotating and counter-rotating twin-screw extrusion technology and screw design and process techniques will be supplemented by hands-on operating sessions.
In its pure form, polylactic acid (PLA) is brittle and has poor mechanical stability. Conventional additives may reduce the material’s strength and elasticity; using core-shell nanoparticles as a filler increases PLA’s toughness while maintaining its strength and modulus.
Among the innovations Polyplastics will showcase are low-VOC-emission resin grades for automotive interiors, a new polyphenylene sulfide grade with improved heat-shock resistance and bump-off molding capabilities.
