Cellasto Explained
Cellasto is the trade name for BASF Polyurethanes’ high performance, microcellular polyurethane elastomer. Cellasto components have been used successfully for more than 60 years as the NVH (Noise, Vibration, Harshness) solution for automotive chassis and suspension applications such as jounce bumpers, shock absorber top mounts and coil spring isolators.
Cellasto is also used in many other applications outside of automotive such as: Spring Ejectors, elevator safety buffers; paper conveying components; friction dampers; sub-frame, motor & body mounts; and more
Properties
- Low compression set.
- High volume compressibility with minimum lateral expansion.
- Excellent mechanical properties & durability.
- Highly versatile – Noise isolation at small amplitude & high frequency.
- Vibration isolation at large amplitude & low frequency.
- Abrasion resistant.
- Resistant to ozone, oils, greases and other aliphatic hydrocarbons.
Uses
- NVH solutions for industry applications.
- Adds premium-quality comfort to office furniture.
- Create safer, more comfortable power tools.
- Reduces NVH for appliances.
- Reduces NVH for improved elevator / heavy equipment operation.
- Improves NVH for superior safety and performance of light vehicles.
- Improves productivity in printing and packaging operations.
- Perfect companion for all sports and leisure equipment.
