Cleanroom Foam Swabs FS series are mainly made of the following materials:

Cleanroom Foam Swabs FS series are mainly made of the following materials:
Sponge head: usually made of polyurethane sponge. Polyurethane sponge has extremely low dust generation, strong liquid absorption, soft and clean, etc. It can effectively clean and not easy to fall off the dust, which can ensure that when it is used in cleanrooms and other environments with high cleanliness requirements, it will not cause pollution to the environment.
Handle: generally anti-static plastic rod. This material has a good function of blocking static electricity, which can avoid static electricity damage to equipment and products, and at the same time provides enough strength and flexibility for operation, ensuring that the user can maintain high precision and stability during operation.
During the production process, the sponge head is firmly connected to the handle by using hot pressing process, sealing edge closure and heat radiating technology, etc. to avoid the pollution caused by using adhesives.

The product specifications of the Clean Room Foam Swabs FS Series usually include the following aspects:

Dimension Specifications

• Length of Cotton Swabs: There are commonly different length specifications such as 75mm, 100mm, 150mm, and 200mm to meet the requirements of different cleaning scenarios and operational needs. For example, in the cleaning of some small precision instruments, the 75mm short cotton swabs are easy to operate; while for the cleaning inside some larger equipment, the 200mm long cotton swabs can reach deeper inside.
• Size of Sponge Tips: The diameter of sponge tips is generally available in specifications such as 3mm, 5mm, 8mm, and 10mm, and the length has options like 5mm, 10mm, and 15mm. Smaller sponge tips are suitable for cleaning fine gaps and small holes, such as the gaps between the pins of electronic components; larger sponge tips can be used for wiping large areas, like the cleaning of optical lenses.

Packaging Specifications

• Individual Packaging: To ensure the cleanliness and independence of the cotton swabs, some products are individually packaged, which is convenient for individual use in a sterile environment. It is often used in fields with extremely high hygiene requirements such as medical treatment and scientific research.
• Multi-piece Packaging: There are also packaging specifications with different quantities such as 10 pieces per pack, 20 pieces per pack, and 50 pieces per pack, which are suitable for scenarios with relatively large usage, such as in electronics manufacturing workshops.
• Whole Box Packaging: The whole box packaging usually contains 100 pieces, 500 pieces or 1000 pieces, etc., which is suitable for enterprises’ bulk purchases and long-term use.

Performance Specifications

• Cleanliness Level: Generally, there are products with different cleanliness levels such as ISO 4 level, ISO 5 level, and ISO 6 level available for selection. The higher the cleanliness level is, the lower the dust generation and other indicators of the cotton swabs will be, and the more suitable they are for high-demand clean room environments.
• Anti-static Performance: There are different levels such as ordinary anti-static and high anti-static. The anti-static performance is usually measured by surface resistance, and common surface resistance values include specifications like 10⁶ – 10⁹Ω and 10⁹ – 10¹²Ω, etc., to meet the anti-static requirements of different electronic devices and so on.
