Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

A multilayer tube, particularly for fluids, includes a sheath made of fluorinated polymers which is located in an innermost layer, which is adapted to be in contact with a circulating fluid, and is constituted by coupling a first, nonconducting material to a second, black-pigmented material that is electrically at least antistatic in the form of one or more continuous strips. The sheath has a smooth internal surface and is reinforced with external layers that are predominantly made of rubber.

A method for manufacturing a composite airtight layer (20) used in the composition of a tire (30) comprises: a film (21) made of thermoplastic material is heated such that the film is able to plastically deform; the film is deformed (120) with the aid of corrugating means, the thickness of the film (21) being in a range from 0.01 to 0.2 mm, and the film having corrugations with a pitch and amplitude chosen in a range from 0.1 to 10 mm so as to give the film a given elongation capacity; the film is cooled such that the corrugated film is no longer able to be plastically deformed; and the corrugated film is coated in a matrix (22) of elastomer material, so as to form a composite airtight layer (20).

A protective film includes an adhesive material configured for “dry” application to a surface that is to be protected, such as the surface of an electronic device. An installation assembly that includes the protective film is configured to minimize or eliminate contact with the protective film as it is applied to the surface that is to be protected. Methods for manufacturing a protective film and an installation assembly that includes the protective film may be effected in contaminant-free conditions. Methods for applying the protective film are also disclosed, as are devices (e.g., electronic devices, etc.) with at least one surface covered with a protective film.

A packaging material comprising a graphene-reinforced polymer matrix composite (G-PMC) is disclosed. The packaging material has improved barrier resistance to gas and liquid permeants. Also disclosed is a method of improving barrier resistance of a polymer to a permeant, the method comprising forming a graphene-reinforced polymer matrix composite within the polymer. The packaging material may be used for packaging food, drug, perfume, etc. and to make various containers.
