Industrial Filtration

perforation for industrial applications and sound absorptionSound waves

By applying perforated materials to sound-absorbent backing, both automotive and HVAC suppliers have significantly reduced undesirable sound migration from sources such as engine and road noise as well as air turbulence in home and industrial HVAC flexible ductwork.

Adhesive bond strength between two structures

Asphalt roofing suppliers have discovered that perforated substrates allow them to filter and control the migration of decorative granules during the laminating process of roofing shingles. This enables them to increase the bond strength between substrates and reduce fracture due to bending or exposure to extreme cold.
