PCT No. PCT/DE95/00168 Sec. 371 Date Jul. 11, 1996 Sec. 102(e) Date Jul. 11, 1996 PCT Filed Feb. 8, 1995 PCT Pub. No. WO95/21635 PCT Pub. Date Aug. 17, 1995A polymer material (6) is formed from a first polyethylene component (1) having a low density (VLDPE) which is silane-grafted with an organic silane (3) in combination with organic peroxide (4) and is cross-linked through storage in a damp environment and/or in water. The polymer material (6) can be processed into medical instruments under dry conditions prior to cross-linkage. After cross-linkage the medical instruments made from the polymer material (6) exhibit a high degree of transparency, are non-buckling and flexible. The polymer material (6) is produced in an extruder, preferentially in a double-worm extruder.
