METHOD FOR MAKING A PART WITH CLEARANCE VOLUME BY ROTATIONAL MOULDING AND RESULTING PART |
摘要 |
<p>A cylindrical element is manufactured by a process which includes depositing successive layers of thermoplastic materials in a cycle by rotation moulding, or by a technique enabling a deposit of successive layers, the cycle including at least one deposit by rotation moulding or by a technique enabling deposit of successive layers at a temperature from 170 to 240° C. The cylindrical element contains at least one layer containing an ethylene-vinyl alcohol copolymer with a density at the above temperature of between 0.94 and 1.4, and a melt flow index of between 1.3 and 4.2 g/10 minutes.</p> |
