NB-10和NB-20是由环氧丙烷和二氧化碳制成的聚合物。它们是无定形的线性脂肪族聚碳酸酯聚合物。二氧化碳约占聚合物质量的40%。应用:NB聚合物可用作粘合剂或添加剂,以改善涂层或粘合剂的性能,用于电子、铜焊和陶瓷等高性能应用,其中快速分解和低灰份含量是有利的。特点:与现有粘合剂相比,NB聚合物氧化、挥发迅速、均匀,生成二氧化碳和水,灰渣较低。其可忽略的污染使其成为高性能应用的理想牺牲材料。它分解迅速,清洁,环境友好。NB聚合物在相对较低的温度下分解,并可溶于许多常见的低成本溶剂,包括丙酮和甲基乙基酮。 NB-10 and NB-20 are polymers produced from propylene oxide and carbon dioxide. They are amorphous, linear, aliphatic polycarbonate polymers. Carbon dioxide accounts for approximately 40% of the polymer mass. Applications: NB polymers can be used as binders or additives to improve the properties of coatings or binders for high performance applications such as electronics, brazing, and ceramics where rapid decomposition and low ash content are advantageous. Features: The NB polymers oxidize and volatize rapidly and uniformly into carbon dioxide and water with low ash residue compared to existing binders. Its negligible contamination makes it ideal as a sacrificial material for high performance applications. It decomposes rapidly and cleanly and is environmentally friendly. The NB polymers decompose at relatively low temperatures and are soluble in many common, low cost solvents including acetone and methyl ethyl ketone. |
