Abstract
Disclosed herein are a biomass composite composition and a foaming method thereof. The biomass composite composition includes (a) polyester alloy containing biodegradable polyester and petrochemical plastic, (b) reinforcing agent, (c) foaming agent, (d) compatibilizer, (e) lubricant, and (f) impact modifier. The biomass composite composition of the present invention is biodegradable and of heat resistance and melt strength suitable for manufacture of foam products.
Claims16
A biomass composite composition capable of providing a composite from which a foamed product having good heat resistance and strength is formed, comprising:
- (a) a polyester alloy containing 40-50% by weight of biodegradable polyester and 50-60% by weight of petrochemical plastic;
- (b) 15 to 20 phr of reinforcing agent;
- (c) 0.1 to 5 phr of foaming agent, wherein said foaming agent is core-shell expandable microsphere or core-shell expandable microsphere masterbatch made from said core-shell expandable microsphere;
- (d) 1 to 3 phr of compatibilizer;
- (e) 1 to 3 phr of lubricant;
- and
- (f) 1 to 3 phr of impact modifier.
