Grodnamid PA6-L-U2 is an injection-molding grade of impact-resistant polyamide 6 produced to Soviet\/post-Soviet-era standards. Grade designation: L \u2014 injection-molding, U2 \u2014 level-2 impact modification. It is produced to GOST 11262-80 (mechanical properties) and OST 6-11-498-79 (glass-filled and modified polyamides), which makes the grade directly compatible with Soviet-style design documentation still in force at many machine-building, defense-industry and transport-sector enterprises in the CIS region.<\/p>\n
Key niche: manufacturing products to legacy GOST\/OST standards<\/strong>, where switching to EN\/ISO alternatives would require recertification, strength recalculation and updates to drawings and design documentation. Manufacturers working with government defense orders, the railway industry and heavy machine building, where documentation references GOST 11262 or OST 6-11-498, can continue using Grodnamid PA6-L-U2 without changing their specifications.<\/p>\n Typical parameters (impact-resistant PA6 per GOST 11262): density 1.13 g\/cm\u00b3, yield strength 50\u201360 MPa (dry specimen), elongation at break 50\u2013150 %, notched impact strength 6\u201310 kJ\/m\u00b2 (per GOST 4647), Vicat softening temperature 195\u2013210 \u00b0C, continuous service temperature up to 80 \u00b0C (dry). Water absorption typical for PA6 \u2014 ~9 % at saturation.<\/p>\n For new projects<\/strong> that can be designed to EN\/ISO specifications, we recommend considering modern equivalents from our range with an extended set of properties and UL\/IEC certifications:<\/p>\n Grodnamid is a trademark of Grodno Azot OJSC (Belarus). Supply is possible either as the original grade or with substitution by an equivalent from the Material Wizard range, depending on customer requirements. The listed values are measured by in-house methods close to GOST 11262-80, OST 6-11-498-79 and ISO. This information is for reference only and is not an official batch data sheet.
