A laminate sheet material comprising a first layer comprised of polymeric material and a second layer comprised of non-metallic fibers. The first and second layers at least collectively contribute to the laminate having at least one of a passing Flammability Value, Flame Propagation Value or Burnthrough Value. The laminate sheet material is useful, for example, in vehicles (e.g., aircraft), insulation blankets, insulation systems, and systems for limiting exposure of flammable insulation to an ignition source.

Vacuum glazing pillars delivery films and methods for insulated glass units

Pillar delivery films for vacuum insulated glass units. The delivery films include a support film or pocket tape, a sacrificial material on the support film, and a plurality of pillars. The pillars are at least partially embedded in the sacrificial material or formed within sacrificial material molds, and the sacrificial material is capable of being removed while leaving the pillars substantially intact. In order to make an insulated glass unit, the delivery films are laminated to a receptor such as a glass pane, and the support film and sacrificial material are removed to leave the pillars remaining on the glass.

Firm silicone rubber foam thermal insulation

A thermal insulation/protection barrier that provides thermal insulation and protection to battery cells of a battery assembly. The barrier includes a cured silicone rubber foam layer comprising a plurality of firming particles disposed within the silicone rubber foam layer in an amount sufficient to impart additional firmness to the silicone rubber foam layer so that it takes a greater compressive force to compress the foam layer to a desired compression value, compared to the same silicone rubber foam layer without the firming particles.

Structured lamination transfer films and methods

Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.
