ADDITION OF LIQUID LUBRICANT TO POLYURETHANE FOAM TO IMPROVE HANDLING CHARACTERISTICS Abstract of the Disclosure Improving the handling characteristics of flexible, resilient, particulate polyurethane foam by adding a small quantity of liquid lubricant to the surface of the foam to prevent clumping. Applying as little as about 0.5 percent to about 20 percent by weight of a liquid lubricant such as mineral oil to the surface of the particulate foam facilitates more uniform filling of equal-volume containers with particles of said foam and reduces the container-to-container weight variation.
