摘要： Stabilized polyethylene materials which offer an advantageously balanced combination of thermal, mechanical and processing properties, and which maintain their physical properties in chlorinated water environments are disclosed. The materials include an antioxidant system with components to provide extraction resistance in hot water environments and additionally provides oxidation resistance to both chlorine in the water interior of the pipe and oxygen in contact with the pipe's exterior.

摘要： Layered, water vapor permeable composite comprise at least one water vapor permeable film layer and at least one substrate layer, the water vapor permeable film (i) comprising at least one film forming polymer and at least one inert porous filler, (ii) having a water vapor transmission rate of at least 1000 g/m2/day, and (iii) activated. Representative film forming polymers include ethylene interpolymers, and representative fillers include silica glass beads. One exemplary method of activating the film is to subject it to sufficient pressure such that the glass beads are crushed within the film matrix.
