Sorbothanes

Sorbothane is a proprietary viscoelastic polymer discovered in 1982 by BTR plc. It is a man-made, polyurethane-based material known for its unique shock-absorbing and vibration-damping properties. Sorbothane is a thixotropic material, meaning its viscosity changes with applied stress. When subjected to impact, it deforms and absorbs the energy by converting it into heat. This dissipation of energy is highly efficient, making Sorbothane effective in protecting against shock and vibration.

The material's composition gives it a distinctive soft, gel-like consistency while maintaining structural integrity. It is non-toxic and resistant to environmental degradation, including ozone and UV exposure, although it can degrade in prolonged contact with oils and solvents. Sorbothane is often cast into specific shapes to suit various applications.

Sorbothane finds widespread use in a diverse range of industries. In the sporting goods sector, it is incorporated into insoles and footwear to reduce impact on joints during athletic activities. Medical applications include prosthetic components and orthotics for improved comfort and shock absorption. The material is also utilized in industrial settings for vibration isolation in machinery, protective padding for sensitive equipment, and in acoustic dampening solutions. Its ability to absorb energy and dampen vibrations makes it a versatile material for enhancing comfort, performance, and durability across many fields.
