Abstract: A fire resistant (FR) pressure sensitive adhesive (PSA) comprises a blend of: a) a (meth)acrylate polymer comprising cationic monomer units; and b) a non-halogenated flame retardant. In some embodiments, the cationic monomer units comprise cationic quaternary amine groups. The (meth)acrylate polymer may additionally comprise anionic monomer units, in which case the molar ratio of anionic monomer units present in the polymer to cationic monomer units present in the polymer is typically less than 0.9. The FR PSA may be aqueous based and may be free of common solvents. The FR PSA may demonstrate improved flame retardance with good compatibility between PSA and flame retardant, and may retain compatibility even at high loadings of flame retardant.

Abstract: Provided is a multilayer thermal insulator and related method that use a non-woven core layer comprising non-meltable and flame-resistant polymeric fibers. One or more scrims are disposed on the opposing major surfaces of the non-woven core layer, and a peripheral edge of the one or more scrims is either edge sealed or capable of being edge sealed to substantially encapsulate the non-woven core layer within the one or more scrims. Optionally, a binder is provided on the scrims or non-woven core layer to facilitate edge sealing. The provided insulators are essentially dust-free and capable of passing stringent flammability standards.

Abstract: A cable includes a plurality of conductor sets. Each conductor set extending along a length of the cable and includes two or more insulated conductors, each insulated conductor including a central conductor surrounded by a dielectric material that includes polyolefin, a brominated flame retardant, and antimony trioxide. First and second conductive shielding films are disposed on opposite first and second sides of the conductor set, including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second shielding films in combination substantially surround the conductor set, and the pinched portions of the first and second shielding films in combination form pinched portions of the conductor set on each side of the conductor set. The cable includes an adhesive layer bonding the first shielding film to the second shielding film in the pinched portions of the conductor set.

Abstract: An assembly includes an enclosure including first and second regions spaced apart along a first direction, and a plurality of spaced apart acoustic baffles arranged along a second direction different from the first direction and disposed in the enclosure between the first and second regions. The plurality of spaced apart acoustic baffles includes adjacent first and second acoustic baffles. Each of the first and second acoustic baffles include an acoustically absorptive layer disposed on a sheet having a specific airflow resistance greater than 200 MKS Rayl. The first and second acoustic baffles define a channel therebetween. At least a portion of the channel extends along a longitudinal direction making an oblique angle with the first direction.
