Are you a plastics processor, lighting manufacturer or in general from the manufacturing industry, and in some applications the standard properties of the raw or finished materials used are not sufficient for the planned use?
This is where we come into play ... then a "normal" ABS becomes, for example, a highly conductive plastic that provides full ESD protection and is still resistant to chemicals and offers a high level of aesthetics as a visible part! That will not do? Sure it's possible!
And many more ... many ... more, previously impossible combinations of properties.
