Sound absorption and insulation material
Product description
The original super fine polyester fiber is made by combing and laminating and hot pressing bonding. The fibers are three-dimensional cross and intertwined, showing many small gaps. The sound can be formed in its cavity with proper density structure, so as to effectively realize the sound absorption and noise reduction function. At the same time, it has good heat insulation and heat preservation performance.
Characteristic
High efficiency sound absorption, heat preservation and energy saving
• Elastic, flexible, moderate hardness, and permanent shape
• Easy to process, easy to cut, can be ultrasonic welding, adhesive bonding
• Light weight (about 30kg / M) ³）， Moderate fluffy structure
• Long life, up to 70 years in dynamic environment
• Environmental protection, recyclable and renewable
• It can compound many kinds of surface, such as glass fiber aluminum foil facing, orange peel aluminum facing, black flame retardant cloth, etc
• Aluminum foil is not easy to absorb water Used to replace glass fiber cotton or rock wool
Application
• Trains, trucks, buses, excavators and mining equipment, walls, roofs and firewalls
• Ship, engine room, partition wall and deck
• Noise control and heat insulation of air conditioning system high voltage equipment
