Abstract
The disclosure provides tubes comprising ultra high molecular weight poly(ethylene) (UHMWPE). Such tubes can have thin walls and be suitable for applications, e.g., as catheter liners. Methods for preparing such tubes include dip coating a core into a dispersion comprising the UHMWPE, where the dispersion advantageously further comprises an eco-friendly solvent and can optionally include one or more additional components (e.g., fillers and/or other polymers).
Claims23
An Ultra High Molecular Weight Polyethylene (UHMWPE) tube,
- wherein the tube comprises distinct, partially fused UHMWPE particles, wherein the tube exhibits:

- and
- b. a tensile stress at break greater than 6 MPa;
- and
- c. a storage modulus of greater than 20 MPa at 37° C.
