ABSTRACT:
A process and apparatus are provided for making desired shapes of urea-formaldehyde suitable for use as insulation from urea-formaldehyde foam. Fluid urea-formaldehyde foam (A) is formed into discrete particles (A') in particle generator (10) which also partially cures particles (A'). After particles (A') are fully cured, they are blended with fluid urea-formaldehyde foam in mixing apparatus (11) which includes blending head (66) to produce mixture (C) which is a coherent mass. Mixture (C) is molded to the desired cross-sectional shape by molding conveyor (12). Cutter (132) cuts formed mixture (C) into the desired length. Thereafter oven (146) is utilized for fully curing the product which is then enclosed in a suitable packaging material.
