We make polyurethane tubes(by extrusion) for medical devices. Polyurethane material we use has 40% BASO4 and hardness of material is 90 Shore A. The tubes made out of this material stick together and causing lot of trouble in handling. We have extended the cooling water tank but no improvement. Can anyone provide a solution to avoid this stickiness.

If your application allows it, you could to add an anti-blocking agent to your formulation. Otherwise have a look at the attached guide of an example how extrusion parameters may be used to minimise blocking.

Thanks for your response. But I can not add anything to the formulation.
