The present disclosure relates to a composite article that may include a structural substrate, a multilayer fluoropolymer film that can include a high-melt fluoropolymer layer and a low-melt fluoropolymer adhesion layer that may contact the structural substrate and the fluoropolymer film. The high-melt fluoropolymer layer may have a melting temperature A1 and the low-melt fluoropolymer adhesive layer may have a melting temperature A2. The melting temperature A2 may be less than the melting temperature A1.

Multilayer composite article

A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.

Composite and method for making

A composite belt may include a profile, and a belt. The profile may have a strip, and nodules. The profile may be attached to the belt such that each nodule extends out from the belt. The composite belt may be included in a cooking apparatus that may also include a housing, a heat source, and a drive roller.

Composite belt profile

A grilling belt includes a flexible support having first and second major surfaces, an extruded fluoropolymer layer overlying the first major surface, and a cast or skived fluoropolymer layer overlying the extruded fluoropolymer layer. Another grilling belt can include a support having first and second major surfaces, and a first fluoropolymer film overlying the first major surface. The support can include a first fabric having a first bias angle, and a second fabric laminated to the first fabric and having a second bias angle different from the first bias angle by between 20&#xb0; and 160&#xb0;.

Cooking belt

A cooking release material includes a layer comprising fluoropolymer. The cooking release material has a major surface having nucleation structures in a density of at least 10 per square inch. The cooking release material can include a reinforcement material, the layer coated over the reinforcement material. The cooking release material can include a second layer forming the major surface.

Cooking release sheet materials and release surfaces

A blended solid composition is provided containing a fibrillatable microparticulate PTFE polymer in an unfibrillated state and at least one elastomeric and/or fluoroplastic component. The composition is useful in making microfiber-reinforced solid compositions and articles produced therefrom.
