Saint-Gobain Seals has launched their new polyamide-imide (PAI) based Meldin® 4000 series, developed as a result of their collaboration with newly acquired LS Kunststofftechnologie GmbH, a German manufacturer of high-performance thermoplastic components for the automotive, medical and industrial markets. The December 2013 acquisition of LS Kunststofftechnologie GmbH provided Saint-Gobain Seals with the knowledge and long standing experience in polyamide-imide (PAI) compounds, which strengthened their polymer solution portfolio, especially in the automotive market. This new series is part of their Meldin® product line, which includes the Meldin® 1000 and 5000 Series, and complements their Meldin® 7000 thermoset materials.
Meldin® 4000 compounds are processed by injection molding with a very limited number of shapes available for prototyping activity. The compounds are stiff, retain high mechanical strength at elevated temperatures, are extremely durable even when used in harsh applications in regards to wear, and are chemically compatible with all common automotive fluids (fuels and oils). Due to the inclusion of these high-performance properties, the Meldin® 4000 product becomes a very suitable replacement for metal components, having the advantage of being much lighter since specific gravity is 80% less compared to steel.
The following are the main features and benefits of the Meldin® 4000 series:
The Meldin® 4000 series is also available in various grades with distinct characteristics, each being designed for specific applications:
With the new launch of the Meldin® 4000 series and its added value especially in powertrain applications, the Meldin® product line has become more robust as it is also being used in other automotive segments (e.g., braking systems components and oil pumps gerotors) as well as in other key markets such as oil and gas (for bushings and back-up rings on high-pressure ball valves and swivels for FPSO: floating production, storage and offloading); industrial (for piston rings in refrigeration compressors and bearings in appliance motors); and life sciences (for shaft bearings in surgical tools and dental drills and piston rings for medical compressors). These are just a few examples of this product’s versatility.
