PRODUCTION OF IMPACT ABSORBING FOAM

摘要

PURPOSE:To mass-produce a product excellent in impact absorbing characteristics and having stable quality by cutting hard resin foam produced by continuous foaming equipment so as to have a longitudinal cell structure so that the vertical direction of foaming is set to an impact absorbing direction to produce impact absorbing foam. CONSTITUTION:A foamable raw material is reacted in continuous foaming equipment having a mixing head 1 and a conveyor 2 to produce foam. At this time, the foamable raw material is foamed while the side guide plate 3 of the continuous foaming equipment is successively narrowed before the gel time of foaming reaction to form a hard resin foam 4 having a longitudinal foam cell structure. The foam 4 is cut so that the longitudinal direction of foamed cells coincides with an impact absorbing direction to produce impact absorbing foam. By this constitution, the impact absorbing foam wherein the vertical direction of foaming is certainly arranged in an impact absorbing direction is produced. Excellent absorbing characteristics is ensured with respect to a conventional molded product and a product of stable quality is mass-produced.
