Kind Code:
B2
Abstract:
A multi-layer tube containing: (1) a barrier layer made of laminated fluoro resin, and (2) at least one outer layer. The barrier layer has a thickness no greater than 20% of the average thickness of the multi-layer tube, and consists of a homo polymer of chlorotrifluoroethylene having a melting point no greater than 220° C., a melt flow rate (MFR) between 0.1 and 10 g/10min at a temperature of 230° C., and a tensile modulus between 750 and 1500 MPa. The outer layer consists of a styrene elastomer. Optionally, an oxygen barrier layer is included between the outer layer and the barrier layer. The barrier layer and the outer layer are integrally laminated with each other by forming the barrier layer and the outer layer in a co-extrusion manner with an adhesive resin being interposed between the barrier layer and the outer layer.
