POLYOLEFIN MATERIALS WITH REDUCED OXYGEN PERMEABILITY
Abstract:
Polymer compositions with reduce oxygen permeability are described. The polymer compositions may include one or more polyolefin polymers, and a nanoparticle filler. The nanoparticle filler represents about 2 wt.% to 5 wt.% of the weight of the polymer composition and reduce the oxygen permeability of the composition by about 20% or more. Also described are roofing systems that may include an insulation layer and a thermoplastic polyolefin layer made using the polymer compositions to protect the insulation layer from weather degradation.
Abstract(Chinese):

描述了具有降低透氧性的聚合物组合物。 聚合物组合物可以包括一种或多种聚烯烃聚合物和纳米颗粒填料。 纳米颗粒填料占聚合物组合物重量的约2重量％至5重量％，并将组合物的氧气渗透性降低约20％或更多。 还描述了屋顶系统，其可以包括使用聚合物组合物制成的绝缘层和热塑性聚烯烃层，以保护绝缘层免受天气降解。
