Latest Patents
Potthoff holds a patent for a mass and spring system designed for soundproofing. This system comprises a bending-soft heavy plastic layer that serves as the mass and a soft layer that functions as the spring. The spring layer is a gel composed of 10 to 50% by weight of an organic polymer or silicone polymer, combined with 50 to 90% by weight of a compatible plasticizer. At room temperature, this gel exhibits a modulus of elasticity of E' ≤ 5 × 10^5 Pa and an internal loss factor of d ≥ 0.5. This innovative design is particularly applicable to sound radiating surfaces or walls in vehicles.
