JHSW8301 Vibration and Noise Reduction Damper Material is independently developed by Qingdao Polyswell Technology Co.,Ltd. The viscoelastic material system consists of A component, a quasi-prepolymer rich of free NCO, and B component, a mixture of polyetheramines, hydroxyl-terminated polyether, amine extenders and other additives. JHSW8301 can convert mechanical energy into heat energy by the coactions of resin and energy dissipation filler. It is used by itself or in combination with other materials to produce damping protective coatings, anti collision liners, reinforcing layer, and resilient surface on urban metro, tunnel concrete. JHSW8301 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. JHSW8301 can effectively decrease the vibration, noise and impact of high speed train; it can improve the safety and durability of urban metro.
Advantages:
- Excellent vibration & noise reduction, impact resistant.
- Bondable and paintable to various kinds of substrates
- Excellent Waterproofing and Impervious
- 100% Solids, No VOC's, Odorless, No Toxic Vapors
- Wide service temperature (-45~100 ºC)
- Seamless, flexible, slick and non-porous
Recommended Uses:
JHSW8302 high loss non-toxic viscous damper materiais a fast cure system; it can be applied at thicknesses of several ten millimeters, or greater, in a single application. It can be widely used in urban metro vibration and noise reduction; it can also be applied in vehicle, shipping, machinery and high speed railway noise insulation zone and so on.
