Lohmann - Sound Reducing Materials for Noise Reduction

Example: DVD pad

• Easy assembly by custom-fit positioning of several tape stripes on one liner
• Exact positioning due to die-cut form
• Quick processing as only one liner has to be removed
• No curing times compared to liquid systems
• Clean application compared to liquid systems

Example: Cable Fastening.

• Noise-reducing properties, rattle protection
• The flexibility of the tapes guarantees an easy covering process of the wiring harness on the headliner especially in curves
• Effective protection against abrasion of round and flat cables
• Faster production process compared to hot melt systems (no curing time)
• No risk of injuries for workers during assembly process compared to hot melt systems

Example: Single-sided sealing foams

• Good adhesion to plastic surfaces without pre-treatment
• Excellent damping properties
• Excellent sealing properties due to smooth closed cell foam carrier
• Various foam/adhesive combinations possible (different thicknesses and densities)
• Die-cuts in any shapes
• Good processability due to dimensionally stable design

Example: Combination of expanded polypropylene (EPP) and adhesive tape.

• Many different combinations of EPP die-cuts and adhesive tapes are realizable
• Expanded polypropylene has noise dampening properties and high dimensional stability
• EPP can be die cut in any two dimensional form (limited only by EPP raw material block dimension)
