Notice: 

The scope of the published data of the commercial products may vary greatly per molding compound manufacturer and per commercial product. Thus, the data of the plastic molding compounds are only comparable to a very limited extent, let alone useful for a material selection. Our PolSelec software is available for a manufacturer-independent plastic material selection.
