BASF SE has succeeded in developing a semi-crystalline polyamide that allows light to pass through largely unhindered. Ultramid Vision combines very high light transmission with low light scattering. This makes it the world’s first semi-crystalline polyamide for semi-transparent or transparent components in chemically challenging environments.
Additionally, the unique polyamide is UV and temperature resistant, scratch-proof as well as suitable for flame-retardant requirements. Ultramid Vision can be used in various application fields: It recommends itself especially for parts for visual check, illumination or light design. Ultramid Vision presents a versatile alternative to commonly used materials such as amorphous aliphatic polyamides, polycarbonate or styrene-acrylonitrile copolymers.
Ultramid Vision has physical and thermal properties which are similar to conventional unreinforced polyamide 6 compounds. However, it stands apart from these compounds significantly thanks to its exceptional visual properties. While semi-crystalline standard polyamides are nearly opaque, that is visually hazy, at a wall thickness of only one millimetre, one can see easily through parts made of Ultramid Vision at wall thicknesses of up to several millimetres.
Ultramid Vision offers a compelling choice compared to alternative transparent and semi-transparent materials thanks to its balanced property profile of good mechanics and processability together with high temperature, scratch and chemical resistance at an attractive price level. It has outstanding UV resistance and is also suitable for applications involving direct exposure to sunlight.
The UV resistance was tested both for indoor use and under outdoor weathering conditions using conventional accelerated weathering tests. Ultramid Vision also shows excellent stress cracking resistance to sunscreen, cleaning agents and solvents as well as fats and oils.
