Making undercut mouldings |
| abstract |
Undercut mouldings are made by injecting a crosslinkable and foamable composition (15) based on a polymer of ethylene into a mould (11, 12) having an undercutting surface (14). The composition is heated in the closed mould to cause crosslinking and foaming. When the mould is opened the contents expand (16) and free themselves from the undercutting surface. Preferred compositions include homopolymers of ethylene and ethylene/vinyl acetate copolymers containing 1.8% weight of dicumyl peroxide as crosslinking agent and 1.7% weight of azodicarbonamide as foaming agent. |
