Berkshire CHNW60920, Choice 600 Nonwoven Wiper, 9"x9", Case of 6,000
Berkshire CHNW60920, Choice 600 Nonwoven Wiper, 55% Cellulose / 45% Polyester, 9" x 9", Case of 6,000
The Berkshire Choice 600 9" x 9" is a thermally bonded nonwoven cleanroom wiper constructed from a 55% cellulose / 45% polyester blend, offering lower lint generation than the Choice 500 while maintaining good absorbency for ISO Class 5 through ISO Class 8 applications. The higher polyester content (45% vs. 40% in the Choice 500) produces a tighter, more uniform fiber structure that sheds fewer particles during use — making the Choice 600 the appropriate specification when lint control is the primary requirement in an ISO Class 5–8 environment. Like all Choice nonwoven wipers, the Choice 600 is thermally bonded with no chemical binders, making it broadly compatible with IPA, acetone, and most common cleanroom cleaning agents.
MTE Solutions stocks the CHNW60920 in cases of 6,000 sheets (300 wipes per pack, 20 packs per case). The 9" x 9" format is the standard workhorse size for cleanroom bench operations. For the same wiper in 4" x 4" format, see the CHNW60440. For the 12" x 12" format, see the CHNW61220. For higher absorbency at the cost of slightly more lint, see the Choice 500 (CHNW50920).

Frequently Asked Questions
What is the difference between the Choice 600 and the Choice 500 in 9x9?
The Choice 600 (CHNW60920) is 55% cellulose / 45% polyester — higher polyester content gives it lower lint generation. The Choice 500 (CHNW50920) is 60% cellulose / 40% polyester — higher cellulose content gives it better absorbency. Choose the 600 when lower lint is the primary requirement; choose the 500 when absorbency is more important.
What does “thermally bonded” mean and why does it matter?
Thermally bonded means the fibers are fused together using heat rather than chemical adhesives or binders. The absence of chemical binders means there are no extractable compounds that could leach into your process or react with solvents — making the Choice 600 broadly chemically compatible with IPA, acetone, and most common cleanroom cleaning agents.
What ISO cleanroom class is the Choice 600 rated for?
The CHNW60920 is rated for ISO Class 5 through ISO Class 8 environments (equivalent to Federal Standard 209E Class 100 through Class 100,000).
How many wipes come in a case of CHNW60920?
Each case contains 6,000 wipes — 300 wipes per pack, 20 packs per case.
Can the Choice 600 be used with IPA or other solvents?
Yes. The thermally bonded construction with no chemical binders makes the Choice 600 broadly compatible with isopropyl alcohol (IPA), acetone, and most common cleanroom solvents.
When should I choose a nonwoven wiper like the Choice 600 over a knitted polyester wiper?
Nonwoven wipers like the Choice 600 are typically lower cost per wipe and appropriate for ISO Class 5–8 environments. Knitted polyester wipers (like the Choice 700 or Choice 900) offer lower particle generation and are appropriate for higher-classification environments (ISO Class 3–5). Choose the Choice 600 for ISO Class 5–8 applications where cost efficiency and lint control are the primary requirements.
