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.

An ultrasonic transducer includes: a laminate in which a plurality of acoustic members is laminated; and an adhesive layer that includes a silane coupling agent and an adhesive, the adhesive layer joining any two of the plurality of acoustic members to each other, wherein the silane coupling agent has a structure represented by general formula (1):

##STR00001##

wherein R.sub.1s each independently represent a methoxy group or an ethoxy group, R.sub.2 represents a methoxy group, an ethoxy group, or a hydrogen atom, X represents a linear or branched organic chain having 4 or more continuous carbon atoms, and A represents a reactive functional group.

Isocyanate-reactive composition that include a polyol blend, a blowing agent composition, and a catalyst. The polyol blend includes a polyether polyol having a functionality of 2 to 6 and an OH number of 20 to 50 mg KOH/g, which is present in an amount of at least 30% by weight, based on total weight of the isocyanate-reactive composition, and an aromatic polyester polyol having a functionality of 1.5 to 3 and an OH number of 150 to 450 mg KOH/g, which is present in an amount of at least 40% by weight, based on total weight of the isocyanate-reactive composition. The blowing agent composition includes water, the water being present in an amount of 1 to 20% by weight, based on total weight of the isocyanate-reactive composition and in an amount of at least 90% by weight, based on total weight of the blowing agent composition. The isocyanate-reaction composition has a green content of at least 30% by weight, based on total weight of the isocyanate-reactive composition. Polyurethane foam-forming reaction mixtures, polyurethane foams, multi-layer composite articles and methods for their production are also described.

A cover member of the present invention is a cover member to be placed on a face of an object to prevent passage of a foreign matter through an opening of the face, the cover member including: a protective membrane having a shape configured to cover the opening when the cover member is placed on the face; and a first substrate layer joined to one of principal surfaces of the protective membrane. The first substrate layer has a laminated structure including at least two substrate films, and is positioned between the protective membrane and the face when the cover member is placed on the face. The at least two substrate films include a non-foam film and a foam film. The cover member of the present invention is suitable for improving the peelability from a member supply sheet.

Proposed are an eco-friendly automotive interior part, a method of manufacturing the same, and a method of designing the same automotive interior part. The automotive interior part can not only optimally correct physical properties thereof using manufacturing and design methods, but also have eco-friendliness by significantly reducing harmfulness to the human body due to the minimized use of chemicals, while realizing natural wrinkles resembling those of natural leather.
