ADIPRENE® L 315是一种液态氨基甲酸酯聚合物,其末端异氰酸酯基与多胺或多元醇化合物反应,可固化成强弹性固体。当用MBCA L固化时,Adiprene® L 315生成的硬韧性产品在许多性能上接近结构塑料的强度。ADIPRENE® L 315的硫化胶有效填补了弹性体与塑料之间的空隙,将高冲击强度、耐磨性、抗变形性、弹性和延展性结合在一起。这些硫化剂能抵抗热、水、氧、臭氧、油和大多数溶剂的恶化作用。Adiprene® L 315是一种完全饱和的聚合物,在86°F(30°C)下,其可用异氰酸酯含量约为9.5%,布鲁克菲尔德粘度约为14500 cp(14.5 pa-s)。与Adiprene L族的其他聚合物一起使用的合成和加工技术通常适用于Adiprene® L 315,尽管必须考虑到其高活性。Adiprene® L 315的硫化特性表明,它可用于车轮、辊、鞋跟提升机、轴承、金属成型工具、体育用品、球头衬套以及其他正在使用塑料或金属的应用中。 ADIPRENE® L 315 is a liquid urethane polymer which can be cured to a strong, rubbery solid by reaction of its terminal isocyanate groups with polyamine or polyol compounds. When cured with MBCA l , ADIPRENE L 315 yields hard tough products that approach the strength of structural plastics in many properties. Vulcanizates of ADIPRENE L 315 effectively fill the gap between elastomers and plastics, combining high impact strength and resistance to abrasion and deformation with resilience and extensibility. These vulcanizates are resistant to the deteriorating effects of heat, water, oxygen, ozone, oils and most solvents. ADIPRENE L 315 is a fully saturated polymer having an available isocyanate content of about 9.5% and a Brookfield viscosity of about 14 500 cP (14.5 Pa-s) at 86°F (30°C). Compounding and processing techniques used with other polymers of the ADIPRENE L family are generally applicable to ADIPRENE L 315, although allowance must be made for its high reactivity. The vulcanizate properties of ADIPRENE L 315 suggest its use in wheels, rolls, heel lifts, bearings, metal forming tools, sporting goods, ball joint liners, and in other applications where plastics or metals are now being used. |
