  • Patent number: 10358528
    Abstract: 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.
