PRESSURE MATERIAL

摘要

A method of spreading constant or repeated pressure away from one or more pressure points between a user and an item of wear wherein the item of wear comprises a pressure material being either: (i) a thermoplastic material having the composition comprising a mixture of; (a) component (A) an organic thermoplastic elastomer having a hardness below 80 shore A measured at 23°C ( ISO 868); and (b) component (B) which is a non cross-linked and substantially non reactive silicone polymer or a cross-linked silicone polymer, with the exclusion of borated silicone polymers exhibiting dilatant properties; or (ii) a flexible material having the composition comprising a mixture of; (c) an elastomeric material having a modulus at 100% elongation of 0.1- 10 MPa; and (d) 5-80% by weight, based on the total weight of the composition of a non-reactive silicone fluid having a viscosity of 1,000-3,000,000 mPas at 25°C; or (iii) both (i) and (ii). The use of such a pressure material in the item of wear has been found to provide an excellent method of spreading pressure away from pressure points on the item of wear.
