ANTISLIP FLEXIBLE MATERIALS AND METHODS FOR THEIR MAKING AND USE
20220008954 · 2022-01-13 ·

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, sitting 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.

In some aspects, the resin composition also includes a clarifying agent to improve optical clarity of the plate. In some aspects, the plates include a textile disposed on one or both of a first side and the second side of the plate. The textile can provide for improved bonding of the plate to other components such as a chassis or an upper.
