Covestro Makrolon 2407: grade identity and data source<\/h2>\n

Makrolon 2407 is a low-viscosity, UV-stabilized polycarbonate with easy-release characteristics, offered in transparent, translucent and opaque colors. This page refers to the base 2407 grade, not 2407 MAS056, DC or RW2407. Confirm the exact grade and color code on the purchase specification.<\/p>\n

Reference: Covestro’s Makrolon 2407 product data<\/a> and its ISO datasheet<\/a> (edition 18 September 2023), checked on 29 September 2026. Values describe standardized specimens and do not guarantee finished-part performance.<\/p>\n

Covestro identifies this base grade as a non-medical, non-food-contact grade. Do not assume suitability for a medical device or food-contact component. Confirm the exact grade and intended use with the material supplier and define the application-specific validation requirements.<\/p>\n

Plan optical and outdoor requirements explicitly<\/h2>\n

UV stabilization is not a promise of unlimited outdoor life without yellowing. Specify the exposure, color-change limit, impact requirement and intended service duration, then agree on an appropriate validation plan. For an optical component, define the transmitting area, wall thickness, permitted haze, distortion and cosmetic acceptance separately.<\/p>\n

A clear resin does not automatically produce a qualified lens, safety shield or electrical enclosure. Review the drawing, gate location, flow fronts, surface finish and inspection method for the actual use. Weld lines, residual stress, marks and warpage require a process review and trial assessment; easy release does not eliminate these effects.<\/p>\n

Drying and molding reference<\/h2>\n

Covestro lists dry-air drying at 120\u00b0C for 2\u20133 hours, maximum moisture \u22640.02%, standard melt temperature 300\u00b0C and mold temperature 80\u2013120\u00b0C. Confirm current guidance for the exact supplied material before setting a process.<\/p>\n

Record drying conditions and moisture checks where required, together with processing settings and sample results. For multiple cavities, identify the cavity associated with each inspected sample. Agree on how cosmetic and dimensional requirements will be assessed after the required conditioning and finishing.<\/p>\n
