Problems solved by technology

However, for material-technical reasons, large amounts of dye and pigment additives are generally not desired, as this significantly impairs the physical and mechanical properties which are indispensable for the desired product effect
If silver is added to the lining, usually in finely divided form, by mixing into the plastic composition, it is colored but rapidly becomes unattractive due to the strong action of perspiration

Embodiment Construction

[0034] The present invention is illustrated in more detail below with reference to examples, which should be used for illustrative purposes and should not limit the present invention as a whole.

[0035] The polymer formulations described below were used as substrates. Silver in the desired form and / or additionally at least one metal selected from aluminum, magnesium, zinc, titanium, platinum or bronze is added to the substrate or base material. For all materials / samples, the addition of silver was carried out with the aid of a commercially available additive containing 1.6% by weight, which was added in an amount of 0.6% by weight relative to the substrate.

[0036] I, as suitable base material such as use:

[0037] 1) Polysiloxane:

[0038] RTV-polysiloxane gel (two-component gel, polyaddition), e.g. Rhodia 4411 or 4420, optionally mixed with 1 to 15% by weight polysiloxane fluid or silicone oil.

[0039] Formulations of suitable polysiloxane materials are in particular...

Abstract

The invention relates to a material which is provided for use in direct contact with the skin of a user and which contains a percentage in silver that is finely dispersed in said material. The material is provided with a content in another metal that is finely dispersed in the material in addition to the silver content. The metals of the group including aluminum, magnesium, zinc, bronze, titanium and platinum are suitable either individually or in combination and in amounts between 0.1 and 1% by weight. The use of the metal particles is also suitable to conceal discolorations in a pigmented or dyed synthetic material when the material is used in air or on the skin. The metal particles do not impair the properties of the material. The material can be used to produce skin patches of any kind, especially for use in orthopedics.

Description

technical field [0001] The present invention relates to the covering of materials that discolor when used in the air or on the skin, especially due to contact with sweat, especially materials that are not metallic in nature and should not substantially conduct electricity and are designed to come into direct contact with the user's skin . The invention also includes use in various dermal patches and pads and orthopedic articles. Background technique [0002] Plastic products are known to undergo discoloration when applied on the skin due to UV exposure and due to other environmental influences, for example due to contact with body fluids and perspiration. Yellowing occurs particularly frequently with white or lightly colored plastic products. [0003] In the case of plastic pads, for example, yellowing and discolouration can occur especially if they are colored with light or skin tones. This discoloration can give plastic parts a dirty and unattractive appearance and must...
