low environmental impact phenolic foam resin composition thermal insulation performance is improved and phenolic foam using the same

摘要

Challenge To provide a low environmental load phenolic foam thermal insulation performance is improved as compared to the existing phenolic foam. A Phenol comprises resins, hydrocarbon blowing agent, a nucleating agent and additives, Phenolic foam resin compositions the size of closed cells cells forming the foam is 20μm~200μm. The phenol foam has excellent heat insulation performance than the heat insulating performance with the existing phenolic foam and by using a hydrocarbon blowing agent, without the risk factors of global warming, long-term high heat insulation performance there is the advantage of having a. .BACKGROUND
