    • The invention provides for new viscoelastic silicone rubbers and compositions and methods for making and using them. The invention provides for viscoelastic silicone rubbers that are stiffer on short timescales than they are on long timescales. When subjected to brief stresses, they are relatively stiff and elastic, and they resist changing shapes. When subjected to sustain stresses, however, they are relatively soft and accommodating, and they gradually change shapes. When those stresses are removed, they gradually return to their original shapes. These viscoelastic silicone rubbers resist compression set and they are extremely resilient in response to sudden impacts. They can be dense rubbers, foam rubbers, and particles.
    • 本发明提供新的粘弹性硅橡胶及其制备和使用它们的组合物和方法。 本发明提供的粘弹性硅橡胶在短时间尺度上比在长时间尺度上更坚硬。 当受到短暂的应力时,它们相对刚性和弹性,并且它们抵抗变化的形状。 然而,当受到维持应力时,它们相对柔软并且容纳,并且它们逐渐改变形状。 当这些应力消除时,它们逐渐恢复到原来的形状。 这些粘弹性硅橡胶抵抗压缩变形,并且响应于突然的冲击而具有极大的弹性。 它们可以是稠密的橡胶,泡沫橡胶和颗粒。
