| titleOfInvention |
Flexible tube of thermoplastic resin having poor melt flowability and production method and apparatus thereof |
| abstract |
Disclosed is a method and apparatus for producing a flexible tube of a thermoplastic resin having poor melt flowability, the tube having an intrinsic viscosity of at least 3.5 dl/g, a tensile strength at break of 150 kg/cm 2 , a breaking time at hot internal pressure creep of at least 200 hours, an outer diameter of 50 mmφ or less, and a ratio of the outer diameter to the wall thickness of 40 or less. n This tube can be prepared from a thermoplastic resin having poor melt flowability by melting the thermoplastic resin having poor melt flowability in a screw extruder, and melt-extruding the molten thermoplastic resin from a tube die having an L/D of at least 5 provided at a mandrel rotatable with the rotation of the screw. |
