Cellasto® reduces NVH in automotive powertrains

Raise your vehicle’s performance to the next level by incorporating Cellasto® into your powertrain components. Powertrain dynamics are one of the largest sources of noise, vibration and harshness (NVH), so using a superior, resilient and durable material is a must for maximizing power transmission while improving comfort. When you apply this highly versatile microcellular polyurethane elastomer to your mounts, bushings, and couplings, it not only accomplishes that, but it also stabilizes your drivetrain to ensure elevated performance that lasts.
