About Grässlin Kunststoffe
Grässlin Kunststoffe is a solutions-oriented distributor of plastic granulates and compounds with two locations in Germany: GRÄSSLIN NORD GmbH in Kirchlengern (6,000 m² warehouse) and GRÄSSLIN SÜD GmbH in Villingen-Schwenningen (15,000 m² warehouse on approx. 3.5 ha company premises). The company supplies technical plastics, high-performance plastics such as PEI, PPS, TPI and PEEK, thermoplastic elastomers, compounds and masterbatches – available at short notice even in large quantities, thanks to its own warehouses and logistics. Beyond pure distribution, Grässlin Kunststoffe supports projects from feasibility analysis through part and tool design, rheological simulations and FEM calculations (with partner Impetus) to prototype support including 3D printing as well as compounding. Further services include quality control, function integration, training in plastics technology, and support with recycling and sustainability. As part of the Hromatka Group (LPS Holding AG), the company serves industries such as automotive, electrical and electronics, medical technology, construction, household appliances, aerospace, drinking water/sanitary, packaging and consumer goods. With ISCC PLUS certification and a portfolio of sustainable materials such as the bio-based, biodegradable PBS compound BioCelain®, Grässlin is responding to the growing demand for a circular plastics economy.
