S 3809
S 3809 is a glass fibre mat (thickness approx. 7 mm) on one side lined with a perforated aluminum foil (thickness approx. 0.09 mm, hole diameter 1.5 mm, hole content approximately 7%), laminated on a heat resistant bitumen heavy foil and a glass fibre mat (thickness approx. 7 mm). Self-adhesive equipment with a high-quality adhesive system based on acrylate.
Main function:
Airborne sound absorption (absorption) and airborne sound insulation
Applications:
Mechanical engineering, plant constructions, sound insulation cabins, engine compartment, exhaust pipes, catalytic converters etc.
Processing:
The surface must be carefully cleaned from dust, grease, oil and water.
Full area adhesion has to be insured. The adhesion strength is directly dependent from the processing pressure. The material has to be pressed in firmly, e.g. using a feed roll.
Processing temperature: 18 - 25 °C
Storage conditions:
Dry at temperatures between 18 - 25 °C
Max storage time: 6 months
Delivery forms:
