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.

Disclosed is a production method of filtration layers that can be used in many fields, especially surgical masks. The aforementioned filtration layers are thermobond non-woven layers and layers formed by supporting it with an electrospinning method. Thermobond non-woven layer is obtained as a result of a process that includes fiber opening, fiber feeding, carding and bonding.

Insulating articles, assemblies and methods are provided. The insulating articles include a core layer (101,201) containing a plurality of non-meltable fibers; and at least one reinforcement layer (102, 202) disposed on the core layer (101,201). The insulating article has tensile strength of at least 0.75 newtons/millimeter according to ASTM D822 and a tear strength of at least 2 newtons under ASTM D1938, wherein the insulating article has a surface electrical resistivity of at least 15 M-ohm at a relative humidity of 85% and temperature of 30° C., wherein the insulating article has an air flow resistance of up to 2000 MKS Rayls according to ASTM C522, and wherein the insulating article displays a UL94-V0 flammability rating.

It is provided that a layered body having excellent absorption speeds of fuel and the like to the filter media. A layered body comprising a first base material and a second base material, wherein the first base material and the second base material are adhered to each other via an adhesive, the first and second base materials each contain a phenol-based resin and an aliphatic hydrocarbon detected during a retention time of 12.0 to 30.0 minutes under pyrolysis-gas chromatography mass spectrometry (PY-GC/MS), and the adhesive contains 65 mol % or more of a butylene terephthalate unit and 5 mol % or more of a butylene isophthalate unit, and has an acid value of not larger than 100 eq/ton, a glass transition temperature of −10 to 60° C., and a specific gravity of not less than 1.20.

Methods and (articles of manufacture therefrom) including forming an elastic film from a polymer composition; tensioning the elastic film to a stretch ratio of between 2 and 6 in the MD; laminating the elastic film to an extensible facing to provide an elastomeric laminate having a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less.

The present disclosure relates to a polymer film, a preparation method of the same, and a polymer film laminate. Specifically, it relates to a new type of polymer film, which is thin and exhibits excellent absorption performance while having excellent flexibility and mechanical properties. In addition, the polymer film is free from scattering or leaking, and does not require an auxiliary substance such as pulp, so that products can be made thinner and the manufacturing process and costs may be reduced. In addition, the present disclosure also relates to a preparation method of the above-described polymer film, and a polymer film laminate including the new type of polymer film.

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.
