Description

Foam cleanroom wipers are used for precision cleaning in controlled environments. They help remove particles and support contamination control in critical applications.

These wipers are made from reticulated polyurethane foam. The material features a high pore density that improves absorbency and helps trap particles.

The open-cell structure allows liquids to be absorbed quickly. At the same time, it helps reduce particle shedding during use.

These wipers are non-abrasive, making them safe for sensitive surfaces and equipment.

With a 6″ x 10″ size, they are ideal for cleaning larger areas and handling detailed work in microelectronics and cleanroom environments. They can also be used for light cushioning in delicate processes.

Key Features

• Rated for ISO Class 5 cleanroom environments
• Made from reticulated polyurethane foam with 100 pores per inch for exceptional particle trapping and fluid absorption
• Open-cell structure allows rapid liquid uptake while minimizing particle shedding during use
• 1/4″ thickness provides enough body for comfortable handling and effective surface contact
• Non-abrasive surface safe for sensitive components, screens, and delicate equipment
• Good sorptive capacity for use with solvents and cleaning solutions
• Can double as light cushioning or padding to reduce vibration in delicate processes
• Size: 6″ x 10″ for efficient coverage of larger surface areas
• Packaged 20 per bag, 25 bags per case (500 wipers per case)

 
Common Uses

• Screen cleaning in microelectronics manufacturing and assembly
• Precision surface cleaning in ISO Class 5 cleanroom environments
• Solvent application and removal on larger surface areas
• Semiconductor and flat panel display cleaning
• Optical surface and lens wiping where non-abrasive contact is critical
• Pharmaceutical equipment cleaning and surface preparation
• Light cushioning and vibration dampening for delicate components during handling or transport
• General cleanroom surface maintenance requiring high fluid absorption

 
Who This Is For

These foam wipers are a strong choice for microelectronics technicians, process engineers, and cleanroom staff who need high absorbency and gentle surface contact in an ISO Class 5 rated wiper. The 6″ x 10″ format gives more surface area coverage per wipe than standard 9″ x 9″ square wipers, making it especially practical for screen cleaning, larger equipment surfaces, and workstation wipe-downs. The 100-pores-per-inch reticulated foam structure is particularly effective at trapping and holding particulate contamination rather than just pushing it around, which sets foam wipers apart from knit fabric options in fluid-heavy applications. The added benefit of light cushioning capability makes these useful beyond cleaning tasks in facilities that handle fragile components.

FAQ

What is reticulated polyurethane foam?
Reticulated foam is an open-cell foam where the cell membranes have been removed, leaving only the structural skeleton. This creates a highly porous material with very high surface area, which makes it exceptionally good at absorbing and holding liquids and trapping fine particles. The 100-pores-per-inch density on these wipers provides a fine, uniform structure suited to precision cleaning.

Are these wipers safe for delicate screens and optical surfaces?
Yes. The foam material is non-abrasive, making it safe for sensitive surfaces including screens, lenses, and precision components. These wipers are specifically noted for screen cleaning in microelectronics applications.

Can these wipers be used as padding or cushioning?
Yes. The 1/4″ thickness and resilient foam structure make these suitable for light cushioning to reduce vibration or protect delicate components during handling, which is a useful secondary application in electronics and precision manufacturing environments.

Are these wipers compatible with solvents?
Yes. These wipers have good sorptive capacity and work well with a range of solvents and cleanroom-approved cleaning solutions. Always verify chemical compatibility with your specific cleaning agent before use.

What is the size of these wipers?
Each wiper measures 6″ x 10″, which provides a larger cleaning surface than the standard 9″ x 9″ square format and is well suited for screen cleaning and larger surface wiping tasks.

How many wipers come per case?
Each bag contains 20 wipers and each case contains 25 bags, for a total of 500 wipers per case.

How do foam wipers compare to polyester or nylon knit wipers at the same ISO class?
Foam wipers excel at fluid absorption and particle trapping, making them ideal for solvent-heavy applications and screen cleaning. Polyester and nylon knit wipers offer more mechanical cleaning action and are better suited for scrubbing residues from surfaces. The best choice depends on whether your primary need is fluid pickup and gentle contact or more aggressive surface cleaning.
