The embodiments relate to a polyamide-imide film excellent in optical properties and mechanical properties, to a process for preparing the same, and to a cover window and a display device comprising the same. There are provided a polyamide-imide film, which comprises a polyamide-imide polymer and has a reduced modulus of a top surface measured by the nanoindentation method according to the ISO 14577-2 standard of 5.6 GPa or more and a haze of 1% or less, a process for preparing the same, and a cover window and a display device comprising the same.

A resin composition is provided. The resin composition comprises an epoxy resin, a zinc oxide powder and a hardener, wherein the zinc oxide powder has a Mohs hardness ranging from about 4 to about 5 and a diameter ranging from about 0.1 m to about 50 m, and the amount of the zinc oxide powder is more than 0.5 parts by weight and less than 10 parts by weight per 100 parts by weight of the epoxy resin.

Apparatuses and methods are provided for manufacturing a transaction card. The disclosed apparatuses and methods may be used to form a transaction card frame configured to house a data storage component. The card frame may be formed of a resin mixture comprising a thermoplastic elastomer (TPE). The card frame may also have a Shore D hardness in the range of 20-80.

The invention relates to a ball, comprising a biodegradable polymer and one or more additives, such as an electrostatic charge eliminating additive, a density increasing additive, a strength/hardness modifier and/or the like added to the polymer mass during the compounding step. The ball is manufactured by a process generally applicable to the manufacture of polymers, such as injection molding, into a substantially spherical shape and grinding and/or polishing it to its final shape by means of double-sided lapping, barrel tumbling and/or the like. The biodegradable polymer used in the ball is polybutylene succinate (PBS).

An additive composition comprises a plurality of granules. The granules comprise a polymer additive selected from the group consisting of clarifying agents, nucleating agents, and mixtures thereof. About 75 wt. % or more of the granules present in the additive composition have a particle size of about 0.5 mm to about 2.8 mm, and the granules have a particle hardness of less than 50 cN. A method for producing a polymer composition utilizes the above-described additive composition.

Metal oxide-polymer composite particles have a median particle size D50 of 40-75 nm or 100-150 nm and an average RTA of at least 0.06. Alternatively or in addition, metal oxide-polymer composites comprise two or more populations of metal oxide particles differing in size, particle size distribution, or shape. Alternatively or in addition, the use of a multicomponent hydrophobizing system including an alkylsilane to fabricate metal oxide-polymer composite particles increases the tribocharge of the composite particles.

A composite material system having an aggregate bound by an elastomer encapsulant. The composite material (CM) is designed to defeat impinging projectiles by converting the kinetic energy (KE) in the projectile to damage in the aggregate and the elastomer and increasing the thermal energy in the CM and the projectile via frictional heating. In one embodiment, the CM comprises certain kinds of rocks encapsulated (or bound) in a hyper-elastic polymer, such as polyurethane (PU). The CM may be shaped into convenient shapes from modular assembly to create a ballistic resistant surface.
