METHOD AND APPARATUS FOR PRODUCING BIODEGRADABLE FOAM

摘要

Methods, associated products and apparatus are described for the production of biodegradable foam products using a controlled pressure increase due to compressed air and a controlled pressure decrease in pressure as key variabl es during a microwave heating cycle to produce a foamed product. The biodegradable product formed has improved characteristics including a densit y from 10 to 100kg/m3; a soft and resilient structure; cushioning G-value characteristics to cushion an object with a fragility of 15 to 115; and a surface abrasion comparable to polystyrene.
