Polymer product, preferably vehicle tyre

Abstract

The invention relates to a polymer product (2), preferably a vehicle tyre (10), with two sidewalls (11), wherein on the outer surface (1) of the polymer product (2) there is disposed at least one representation (3), which has a two-dimensional area (4) that is covered by a pattern. The invention is based on the object of providing by simple means a polymer product that has on its outer surface at least one two-dimensional area with a pattern, by means of which a higher-contrast representation with a directionally independent contrast can be achieved, and which can also be produced more reliably. The object is achieved by the pattern being a two-dimensional dot pattern, in that each dot is a three-dimensional element (5), which is formed as an elevation or depression of the surface (1), in that each element (5) has a base area (6) and a peak height (S), in that the pattern has elements (5) with a peak height (S) of 0.10 mm to 0.4 mm, preferably of 0.20 mm to 0.30 mm, and in that the pattern has elements (5) that are at a distance (B) from the respectively nearest neighbour of 0.10 mm to 0.50 mm, preferably 0.15 mm to 0.25 mm, wherein the distances (B) are measured between the geometric centroids of the base areas (6) of the elements (5).

Description

technical field [0001] The invention relates to a polymer product, preferably a vehicle tire having two sidewalls, wherein at least one graphic is arranged on the outer surface of the polymer product, wherein the graphic has a planar area, which is covered by A pattern overlay. Background technique [0002] Polymer products are, for example, pneumatic tires for vehicles and housing parts made of plastic by technical equipment. Polymer products have materials (eg PVC, PU, ​​TPO) and / or elastomeric materials (eg rubber). [0003] Here, the term "illustration" includes illustrations, characters, company names, company logos, marks, planes, and the like. [0004] Such polymer products are known, for example, vehicle pneumatic tires. For a monochrome representation of letters or the like on a sidewall using multiple shaded portions in the surface area of ​​the sidewall formed around the letters shown on the tire sidewall, i.e. with non-intersecting linear ridges The pattern o...

AI Technical Summary

Problems solved by technology

Furthermore, due to the directional dependence and the longitudinal extension of the linear ridges of this shaded area, it is disadvantageous when the tire is released from the tire mould.

It is especially problematic that residues of the elastomeric material after curing adhere to the molding surfaces of the curing mold

This type of sticking, which contaminates the curing mold, is undesirable because dirty, undesired tire surfaces can only be molded with a contaminated curing mold

Therefore, time and cost must be spent cleaning the curing mold after fewer curing cycles and is not used as a forming mold during cleaning
