Abstract: The foamed plastics are not bio-degradable and not readily recyclable. How to substitute new foamed buffer materials with lower pollution for foamed plastics became a popular research topic. The paper discussed the effects of microwave power, natural bonding agent, lubricating agent and crosslink agent on foamed buffer material with fibers of old newspaper and inorganic foaming agent. The result showed that increasing of microwave power could be beneficial to decrease the molded time and density of foamed buffer material with fibers of old newspaper. The best foamed properties were achieved with proper dosage of natural bonding agent like wheat flour, glyceryl monostearate sodium borate at the microwave power of 575W.

Abstract: The residues from wheat straw pulping mainly include uncooked chips and fiber bundles. In order to achieve high quality pulp, the residues require removal from the system. It was not necessary that the residues were re-cooked because of its high contents of non-cellulosic constituent. The achievement of low density foamed buffer material with the residues of wheat straw pulping would make the second pollution problem of the residues be solved, and achieve a replacer of foamed plastic material. The paper discussed the producing techniques of foamed buffer material with the residues of wheat straw pulping. The result showed that the best foamed properties of the residues were achieved with proper dosage of natural bonding agent like wheat flour, inorganic foamed agent, crosslink agent, and proper foamed temperature. The density and compression of foamed buffer material with the residues of wheat straw pulping were achieved with 60 kg /m³ and 60 kPa respectively at the optimum foaming condition.
