Abstract: A non-asphaltic breathable sheet is provided that includes at least one breathable polymer layer and at least one nonwoven layer. The breathable sheet may include an open-mesh reinforcing fabric embedded in a breathable polymer layer. The breathable sheet has an advantageous balance of strength, water resistance, and permeability to water vapor.

Abstract: A sheet material is provided that includes a woven layer having a first side and an opposing second side, the woven layer formed from strand including a polyolefin polymer and a nucleating agent; a first polymeric coating disposed on the first side of the woven layer; and optionally a second polymeric coating disposed on the second side of the woven layer. The sheet material exhibits reduced thermal shrinkage.

Abstract: Devices and systems which control the flow of fluid through a conduit are described herein. One flow control device that controls the flow of fluid through a conduit, includes a body having an axis and defining a passage that allows fluid to flow from an upstream position to a downstream position, the valve body having a converging portion in the upstream position with an inner surface that curves gradually inward, but having an annular rim formed by a portion that extends outward from the inward curving shape, and a throat between the converging and diverging portions; and, a flow regulator supported within the body for controlling the flow of fluid through the conduit, the flow regulator having an annular seating surface configured to contact the annular rim of the body.

Abstract: Silicone resins comprising 5 to 50 mole % of (PhSiO3-x)/2(OH)x) units and 50 to 95 mole % (HSiO(3-x)/2(OH)x), where Ph is a phenyl group, x has a value of 0, 1 or 2 and wherein the cured silicone resin has a critical surface free energy of 30 dynes/cm or higher. These resins are useful as etch stop layers for organic dielectric materials having a critical surface free energy of 40 dynes/cm or higher.
