INDUSTRIES
Browse by Industry
Start from the industry and application area to understand vibration, noise and thermal insulation concerns and find candidate materials.
Rail Transit
We jointly evaluate material and component options around vibration, structure-borne noise and weight constraints of car bodies and metal components.
View industry applications →Building & Elevators
For rain impact noise on metal roofs, ventilation ducts and elevator-related components, materials are selected starting from the specific noise source.
View industry applications →Automotive & Appliances
Combining vibration control, weight, adhesion and process compatibility to support component material selection and sample validation.
View industry applications →Marine & Power Equipment
Considering metal component vibration, equipment protection and the operating environment, damping and fire/heat insulation needs are evaluated separately.
