This application relates to elastomeric articles such as gloves, compositions for producing the articles and methods for their manufacture. The elastomeric articles contain particles for detectability of the articles (or portions thereof) by metal detectors and/or x-ray detectors. The articles may contain two different types of particlesone particle type is selected from magnetic particles, highly conductive particles or a combination, and the second particle type is particles containing one or more high atomic mass elements (with an atomic mass of at least 132). The particles may be coated by a corrosion inhibitor coating, or they may be uncoated. The compositions for producing the articles may contain a viscosity modifier.

The ethylene-vinyl alcohol copolymer composition comprises: an ethylene-vinyl alcohol copolymer; and an iron compound; wherein the ethylene-vinyl alcohol copolymer is a saponification product of an ethylene-vinyl ester copolymer prepared by using an organic compound having a half-life of 10 to 300 minutes at 60 C. as a polymerization initiator; wherein an amount of the iron compound is 0.001 to 2 ppm in terms of a metal by weight of the ethylene-vinyl alcohol copolymer composition.

A high flexural strength high density environmental friendly artificial glass composite slab and the preparation method, spherical glass sand or spherical glass powder, filler, unsaturated resin, curing agent, coupling agent, pigment paste and toner. The glass sand or the glass powder has high hardness, good light transmittance, and a smooth surface without pores. The glass powder, filler powder and a hollow glass microspheres fill the gap among the spherical glass sand or the spherical glass powder, and mutually mesh with each other to form a high-density structure. The resulting glass composite slab has the advantages of high strength, high density, wear resistance, shining gloss and good light transmittance, while the surface is smooth and is not likely to be subjected to staining, and it is environmental friendly, non-toxic and non-radioactive.
