Berkshire Unveils New Line of Clean and Absorbent Polyester Nonwoven Wipers

Berkshire Corporation, a manufacturer of contamination control products for cleanroom and critical environments, introduces Surex™, a new class of polyester/cellulose cleanroom nonwoven wiper that is critically clean and absorbent.

Surex™ Wiper from Berkshire

While traditional polyester/cellulose nonwoven wipers have adequate absorbency, these wipers tend to have much higher fiber and particle counts causing concerns for potential contamination. Some specially treated wipers have lower particle and fiber counts but these wipers often have low absorbency, sacrificing a critical component of a wiper's functionality. Surex™ was developed through a proprietary manufacturing process resulting in an ultra-clean wiper with low particles, fibers, and ions without sacrificing absorbency or softness.

In a wiper performance comparison test (IEST standardized test methods) done through a third party test lab, Surex™ outperformed conventional nonwoven wipers with 32x lower in fiber counts and 7x lower in particle counts. In addition, Surex™ has the lowest non-volatile residues and ion traces compared to wipers in its class.

Surex™ is suitable for cleanroom applications (ISO class 5-8) in pharmaceutical, medical device, electronics, laboratory, semiconductor, and industrial controlled environments. Surex™ is available in dry and pre-wetted versions. Product evaluation samples are available immediately through contacting Berkshire
