Polyimide tubing responds to growing catheter specialization


Putnam Plastics (Dayville, CT) is introducing clear polyimide tubing for medical applications that require visual monitoring, UV transparency or imaging transmission. Unlike traditional dark, amber polyimide which has limited options for pigmenting, clear polyimide also allows for a wide range custom colored tubing options.

The new material meets requirements of growing specialization in catheters. Its properties include tensile strength of 17,000 psi (117 MPa) and flexural modulus of 550,000 psi (3,792 MPa). Putnam says it also has excellent resistance to wear, heat, radiation and electrical arcing.
