The present disclosure related to a multilayer protective film that may include a structural PET layer, a first removable adhesive layer underlying the structural PET layer, a first peelable adhesive layer overlying the structural PET layer, a first flame retardant PET layer overlying the first peelable adhesive layer, a second peelable adhesive layer overlying the first flame retardant PET layer, and a second flame retardant PET layer overlying the second peelable adhesive layer. The multilayer protective film may have a lateral flame spread of at least about 20 KW/m, a specific optical density (Ds) of not greater than about 300, and a cumulative specific optical density (VOF) of not greater than about 600.

Multilayer protective film

A method for continuously forming a three-dimensional body from a mixture, the mixture comprising at least 15 vol % solid particles and a radiation curable material. The method allows the continuous production of three-dimensional bodies comprising to a high content ceramic particles at a forming speed of at least 25 mm/hour.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a nonwoven facing and to methods for making such panels. One aspect of the disclosure is a method for preparing an acoustic panel comprising providing a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The method includes disposing directly against the outward major surface of the base structure a sprayable mixture comprising a plurality of fibers, one or more binders, and a dispersive medium. The method includes drying the disposed mixture to provide a facing layer disposed on the outward major surface of the base structure, the facing layer having an exterior major surface opposing the outward major surface of the base structure.

A fiber mat includes an assembly of fibers including a minority portion including a set of polymer fibers and a majority portion including a set of fibers different than the minority portion, wherein the minority portion is a plane parallel to a plane of the majority portion of the assembly of fibers; and a binder including an organic resin, wherein an air permeability of said fiber mat is not substantially different from an equivalent weight fiber mat containing a homogenous mat structure and wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with the equivalent weight fiber mat containing the homogenous mat structure.

Fiber mat, method of making the fiber mat, and bituminous roofing product

A fiber mat includes a unitary assembly of fibers including at least a first set of fibers and at least a first binder comprising an organic resin, wherein the unitary assembly of fibers includes a minority portion and a majority portion different than the minority portion, wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with a fiber mat of equivalent weight containing a homogenous mat structure.

A polymer material including a fluorinated component and a silicone component can exhibit improved performance, such as increased thermal stability. An article can include the polymer material. For example, a coated fabric including the polymer material can exhibit improved dielectric strength. A composition for forming the polymer material can include a dispersion comprising a fluorinated component and an emulsion comprising a reactive silicone component. In an embodiment, a single pass film formed from the composition can have an increased critical crack thickness. A method can include forming a polymer material from the composition.
