Pre-Sales
DS series damped silicone has the characteristics of elastic durability, cushioning and shock absorption, and surface adhesion graded design, which is suitable for pressing or filling small spaces. Damped silicone gel has good viscoelasticity, and when it is subjected to vibration or noise transmitted by the outside world, will produce polymer chain or chain segment movement, and dissipate mechanical energy in the form of heat energy through intermolecular friction during movement, so as to achieve the purpose of shock absorption and noise reduction. The product can be used in electronic and electrical, industrial transportation and other fields to achieve the role of making up tolerances, reducing resonance, and buffering protection.
