Demand for high-performance hot melt adhesives continues to increase as the need for disposable hygiene products, such as adult incontinence diaper, baby diaper, pull-ups diaper, feminine sanitary pads, pantyliner, underpads, grows across the globe. Despite hot melt adhesives being only a small part of the total raw materials used in disposable hygiene products, it plays a fundamental role in delivering the enhanced functionality required for meeting the changing demands of consumers.

Main Adhesives for Disposable Hygiene Products and Nonwoven

1. Construction hot melt adhesive (structure hot melt adhesive)
2. Elastic hot melt adhesive
3. Positioning hot melt adhesive
4. Hook hot melt adhesive
5. Wet indicator adhesive

Wet Indicator Adhesive

It provides fast and distinct color change at the time of wetness, it has less migration or bleeding of color for a clear and noticeable indication.

• Faster indication speed upon insult, it will indicate in the presence of urine in less than 30 seconds.
• Less bleeding of indication color, for clear and noticeable indication. Improve color migration that enhance safety for babies.
• The odor level of adhesive and finished goods are comparatively low, which can meet customers’ requirements.
• High humidity resistance virtually eliminates premature color change. It doesn’t change color after put in the 38℃/RH 90% oven for 8 hours. It can meet the humidity resistance requirement from customers.
• Excellent thermal stability for better machining than standard hot melt wetness indicators.
• AOX testing by 3th party, AOX <5mg/kg.
