    • 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.
    • 一种从用户和磨损物品之间的一个或多个压力点传播恒定或重复压力的方法,其中磨损项包括压力材料,其为:(i)具有包含以下物质的混合物的组合物的热塑性材料: (a)组分(A)在23℃下测得的硬度低于80 Shore A的有机热塑性弹性体(ISO 868); 和(b)组分(B),其是非交联和基本上不反应的硅氧烷聚合物或交联的硅氧烷聚合物,排除具有膨胀性质的硼酸化聚硅氧烷聚合物; 或(ii)具有组合物的柔性材料,所述组合物包含: (c)在100%伸长率下的模量为0.1-10MPa的弹性体材料; 和(d)5-80重量%,基于组合物在25℃下粘度为1,000-3,000,000mPas的非反应性硅氧烷流体的总重量。 或(iii)(i)和(ii)。 已经发现在磨损项目中使用这种压力材料提供了将压力从磨损物品上的压力点传播出来的优良方法。
