Note

• ᵈ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding. Do NOT mix NORYL GTX* resin with other grades of NORYL* resins. Polystyrene and acrylic regrind are effective purging Materials. Use temperature range appropriate for particular purging resin. Regrind must also be dried. Maximum 25% regrind. Dry at recommended temperatures and times for optimum performance. Overdrying can cause loss of physical properties and/or create appearance defects. Do not exceed recommended basic drying time and temperature above or:\n4-8 hrs at 95°C (200°F), 10 hrs max\n6-12 hrs at 80°C (175°F), 16 hrs max\n8-16 hrs at 65°C (150°F), 24 hrs max\nAVOID air circulating tray ovens. Moisture levels in heated ambient air can exceed moisture level in the resin itself, causing moisture ABSORPTION not drying. Avoid melt temperature in excess of 300°C (575°F) and residence times over 6-8 minutes (may affect properties and/or appearance). Nozzle temperature controls assist in elimination of drool premature freeze-off. Shot sizes in excess of 50% barrel capacity can lead to difficulties in providing a consistent, homogenous plastic melt.
• ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
• ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
