| 摘要 |
A method of producing products made of plastics material based on a polymer selected from an ethylene vinyl carboxylate (EVC), polyethylene, an ethylene copolymer, or a mixture of polyethylene and ethylene copolymers is described and comprises a step for the production of a non-cross-linked semi-finished product by injection and moulding and a step for the exposure of the semi-finished product to an electron beam (beta radiation) of an intensity no less than 60 kgy in order to cross-link the polymer.
