Some of my customers are looking for transparent inherently dissipative sheets for vacuum forming trays. The S.R. should be less than 10^6ohms. PS based material. They prefer to extrude sheets without dissipative coating.
As I know, there are some famous compound suppliers in the world such as Premix Oy, but some of them only supply inherently dissipative compound with semi-transparent property.
So how should I solve this problems to the customer?
