Ultrasonics Offer Cost Benefit Over Adhesives

Ultrasonic welding is being considered as a cost-effective replacement for adhesives to bond nonwovens, films, and textiles.

Ultrasonic welding is being considered as a cost-effective replacement for adhesives to bond nonwovens, films, and textiles. With the recent spike in energy prices causing adhesive prices to more than double, manufacturers are searching for new alternatives, according to Herrmann Ultrasonics Inc., Schaumberg, Ill. Ultrasonics reportedly avoid some of the limitations of adhesives, including bleed-through in thin nonwovens and heat distortion of thin films. Thus, cost savings can be realized by using thinner webs. Ultrasonic welding also opens up new capabilities such as bonding multiple layers of material simultaneously and intermittent bonding patterns in a range of shapes. Other key benefits over adhesives include immediate bond strength and low energy costs. Tel: (847) 985-7344 • For a detailed report on this topic, visit www.ptonline.com and enter PTDirect: 839QB.
