ValuSeal-HA®

ValuSeal-HA® is a highly absorbent, ultrasonically sealed, 100% polyester wiper. It is designed to address such concerns as absorbency, purity, strength, and durability, especially for the semiconductor and biomedical markets. ValuSeal–HA® features the highest levels of cleanliness, abrasion resistance, and chemical compatibility required for ISO Class 3 and above environments as well as other applications requiring critical control of contaminants.

The same wiper material can be provided in pre-wetted formats for reduced VOC emissions, increased convenience, increased productivity, improved solvent control and cleaning protocol repeatability and reduced costs.
