Mold temperatures are managed between 17\u00b0C and 65\u00b0C (63\u00b0F\u2013149\u00b0F) using pressurized temperature controllers. Slower injection and low holding pressures are applied to avoid residual stresses.<\/li>\n
  • Low Isotropic Shrinkage:<\/strong> STYRON 678D exhibits extremely low shrinkage (typically 0.3% to 0.6%). This amorphous behavior enables us to hold extremely tight dimensional tolerances for stackable diagnostic labware.<\/li>\n<\/ul>\n<\/section>\n
