An acoustical and thermal insulation product suitable for use in an aircraft is provided, comprising: an insulation layer formed from a sheet of insulation material, wherein the sheet of insulation material is arranged to form a series of undulations defining a series of alternating upper ridges and lower ridges of the sheet, and a plurality of elongated reinforcing members for reinforcing the insulation product.
摘要:
A composite filter media includes a fibrous filtration layer of randomly oriented fibers and one or more pleatable stiffening layers which enable the composite filter media to be pleated and hold or retain its pleats. The pleatable stiffening layer(s) may enhance the dirt holding capacity of the composite filter media especially when positioned upstream of the fibrous filtration layer. The composite filter media may also include a flexible covering layer which functions to block the loss of fibers from the fibrous filtration layer. Preferably, the mean fiber diameter of the fibers in fibrous filtration layer increases and the density of the fibrous filtration layer decreases throughout the thickness of the fibrous filtration layer from one major surface to the other major surface of the fibrous filtration layer.

A single ply membrane roofing system includes a roofing insulation board which, preferably, is at least 45% by dry weight expanded perlite. One major surface of the insulation board is coated with a latex coating comprising, by dry weight, between 48.3% and 96% clay; between 3.1% and 33.3% latex; and between 0% and 34% sodium silicate. A single ply roofing membrane is adhered to the coated major surface of the insulation board with a roofing contact adhesive.

摘要:
By carefully adjusting the molecular weight and amounts of methacrylic acid and maleic acid and/or maleic anhydride comonomers in polyacrylic acid-based fiberglass binders, binder-treated fiberglass cured and B-staged product throughput may be maintained at production rates designed for phenol/formaldehyde binders due to the lower thermal requirements for cure as compared to homopolyacrylic acid-based binder systems.
摘要:
An insulation board suitable for use as a roof insulating board has a density between about 8 and about 15 pounds per cubic foot; a MOR/density ratio of at least 10.5 to 1 and includes, by dry weight, between about 45% and about 76% expanded perlite; between about 15% and about 45% cellulosic fibers; between about 0.1% and about 10% latex binder; between about 2% and about 9% bituminous material; and about 0% to about 3% alum.
