A method for forming an antislip material. A flexible thermoplastic carrier is provided. A hot release surface is provided. Provided is a first layer of discrete thermoplastic particles, sifting on the hot release surface. The discrete particles are above their softening temperatures, providing in the first layer a tackiness. The method includes contacting the carrier with the tacky first layer for sticking the first layer to the carrier, and thereafter removing the carrier, and therewith the tacky first layer stuck to the carrier, from the release surface. Thereby the carrier is provided with a hot, preferably discontinuous and/or elastomeric antislip coating. With a heat energy of the hot coating a bond is formed between the carrier and the coating. The removing of the carrier includes pulling the carrier out of the contact with a pulling-out force. The temperature of the hot release surface is above the melting temperature of the carrier. The carrier would be spoiled, if heated completely to the temperature of the release surface and simultaneously pulled with the pulling-out force. Therefore the contacting time is kept shorter than a minimum time required by a heat of the hot release surface for spoiling the carrier. Flat-topped roughening projections can be included in the antislip coating.

A method of producing a brush for the cleaning of electronic components. In this method, a plastic core is prepared and submerged into a solvent to melt the outer surface of the core. While the outer surface of the plastic core is still partially melted, it is rolled through a trough of powdered polyvinyl alcohol (PVA) such that granules of PVA melt into and subsequently become embedded at the outer surface. As the solvent evaporates, the outer surface of the core re-hardens and the granules of PVA become firmly entrapped at the outer surface. The PVA covered shaft is placed in a mold, which is then filled with a PVA solution. As the solution cures, it forms a strong bond with the PVA granules that are embedded at the surface of the plastic core. Thereafter, the mold components are disassembled, leaving behind the finished cored brush.

A plastic patio paver block comprises a top panel, a sidewall depending downwardly from a periphery of the top panel, a plurality of internal support members that depend downwardly from an inner face of the top panel and that are spaced inwardly from the sidewall, a plurality of drainage openings provided in the top panel, and a granular UV resistant material embedded into an upwardly facing plastic face of the top panel, wherein a portion of the granular UV resistant material is partially embedded in the upwardly facing plastic face.

A method for treating a plastic block comprising using heat to embed a UV resistant material into an outer face of the plastic block wherein, once embedded, the UV resistant material provides a coating on the outer face. A method for treating a plastic block comprising using compressive force to embed a UV resistant material into an outer face of the plastic block wherein, once embedded, the UV resistant material provides a coating on the outer face.

A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.
