Material Technology Focus
Our products focus on water-based vibration damping and noise reduction, sound absorption and insulation, and fire and heat insulation applications. Suitable substrates, application methods and test conditions differ between models. We describe uses and conditions based on the current documentation for each model, so that selection discussions rest on clear material information.
04
Application Evaluation
Application discussions start from the customer's actual conditions: substrate and location, sources of vibration and noise, service temperature and environment, application method, thickness limits and industry requirements. Based on this information we discuss candidate materials, documentation and verification methods; specific suitability is confirmed by sample evaluation under the relevant conditions.
05
Sample Communication
Customers in China can request a free 1 kg sample, freight collect; no samples are shipped overseas. When applying, you may describe the application area, substrate and intended evaluation to facilitate technical communication. Business and technical needs are routed to Sales and Tech respectively, so that questions reach the appropriate contact.
