Cleanroom Wiping Paper: Standards & Guidelines

Posted on by

1. Product Introduction
Cleanroom wiping paper is a high-performance cleaning consumable specially designed for clean environments. It is widely used in electronics manufacturing, optical instruments, medical devices, precision machinery, and other fields with strict dust-free requirements. Its core function is to efficiently remove surface contaminants while preventing fiber shedding or secondary contamination, thus ensuring the cleanliness of the production environment and product yield.

2. Material and Process Standards

  • Material Composition:
    The wiping paper adopts a nonwoven composite structure made of 45% polyester and 55% wood pulp fibers.

  • Polyester fibers: Provide high strength, chemical resistance, wear resistance, and tear resistance, reducing fiber shedding during wiping.

  • Wood pulp fibers: Enhance liquid absorption and softness, improving the adsorption of fine particles.

  • Basis Weight (GSM):
    The unit weight ranges between 56-68 g/m², classified by application scenarios:

    • Standard type (56-60 g/m²): General wiping for routine cleaning.

    • Enhanced type (61-68 g/m²): For high absorption needs or heavily contaminated scenarios.

3. Physical Performance Requirements

Test Item Test Standard Qualification Criteria
Tensile Strength (MD) GB/T 24218.3 Must meet customer requirements
Absorption Rate (DI Water) GB/T 24218.6 Must meet customer requirements
Fiber Shedding IEST-RP-CC004.3 Must meet customer requirements
Abrasion Resistance (Dry) ASTM D3886 Must meet customer requirements

4. Chemical Cleanliness Standards
Cleanroom wiping paper is generally produced in Class 10,000 cleanrooms and is not washable. It is suitable for lower cleanliness or peripheral cleanroom use. For environments requiring Class 10,000 or better cleanliness, cleanroom wipes are recommended, which can meet up to Class 10 cleanliness.

5. Packaging and Labeling Specifications

  • Packaging Formats:

    • Roll form: Also called jumbo roll wiping paper, with 500 sheets per roll, convenient for pull-out use.

    • Bagged form: Also known as 0609 wiping paper, individually sealed packages containing 150-1200 sheets depending on size.

  • Color Coding:
    White, blue, and green are common colors. In electronics, white is more widely used, while blue and green are more common in industrial wiping scenarios. In China, white is predominant, whereas blue and green are more popular in Europe and America.

6. Testing and Certification
Customers can request RoHS certification and TDS (Technical Data Sheet) reports from suppliers to ensure compliance.

7. Application Guidelines

  • Electronics Industry:
    Recommended use with IPA solvent for wiping PCB boards; single sheet single-direction wiping is advised.

  • Optical Field:
    Prefer blue-colored microfiber laminated products to avoid scratching coated surfaces.

  • Medical Sterilization:
    Compatibility verification with EO/γ-ray sterilization is required; packaging materials must comply with YY/T 0698.2.

Summary:
Standardized production and scientific selection of industrial cleanroom wiping paper are crucial to maintaining modern industrial cleanliness. Users are advised to choose wiping papers based on actual scenario requirements, considering material properties, cleanliness level, and packaging formats, while regularly verifying suppliers’ test reports and compliance documentation.

Cleanroom vs. Ordinary Wipes: Key Differences

Posted on by

In the world of industrial and high-precision cleaning, choosing the right type of wiping material is crucial. While cleanroom wipes paper (often called “0609 cleanroom paper” in China) and ordinary paper may appear similar, their materials, manufacturing environments, and performance differ significantly. This article breaks down their core differences and guides you in selecting the right product for your application.

1. What Is Cleanroom Wipes Paper?

In the Chinese market, cleanroom paper typically refers to dust-free wiping paper, widely known as 0609 cleanroom paper, used for contamination control. In international markets, “cleanroom paper” may also refer to A4 printing paper or writing pads used in cleanrooms.

Composition:

Made from a blend of wood pulp and polyester fibers, cleanroom wipes paper is technically a nonwoven fabric, not traditional paper.

Manufacturing Process:

Produced in cleanroom facilities, ensuring low particle release, chemical resistance, and high cleanliness.

Key Features:

  • Rapid oil and dirt removal

  • Strong solvent resistance

  • Soft texture, non-abrasive

  • Low particle shedding, high cleanliness

Common Applications:

Used extensively in electronics, semiconductors, optics, and laser industries, where contamination control is critical for product quality and process stability.

2. What Is Ordinary Paper?

Ordinary paper refers to materials made from 100% wood pulp or paper pulp and is classified into two main types:

Household Paper:

Includes toilet paper, kitchen paper, and writing/printing paper produced in conventional paper mills.

  • Typically disintegrates in water

  • Used in daily hygiene and consumer applications

Industrial Wiping Paper:

Used in manufacturing and maintenance environments for cleaning machinery and surfaces.

  • Made with long-fiber pulp for higher strength

  • High absorbency and durability

  • May or may not be produced in cleanrooms

3. Comparison Table

Attribute Cleanroom Wipes Paper Ordinary Paper (Household/Industrial)
Material Composition Wood pulp + polyester (nonwoven) 100% wood pulp or paper pulp
Particle Release Very low, minimal shedding High, prone to dust and fiber release
Cleanroom Grade Suitable for Class 100–10000 Not suitable for cleanroom use
Solvent Resistance High Poor (especially household paper)
Wet Strength Maintains structure when wet Weak when wet (household), varies for industrial
Application Fields Cleanrooms, electronics, optics Household, general manufacturing

4. Usage Recommendations

  • For cleanroom or high-purity wiping: Use cleanroom wipes paper (e.g., 0609 model).

  • For general industrial cleaning: Use industrial wiping paper with high wet/dry strength.

  • For household use: Ordinary toilet or kitchen paper is most cost-effective.

5. Conclusion

Cleanroom wipes paper and ordinary paper serve entirely different purposes. Choosing the correct type not only ensures effective cleaning but also protects your processes from costly contamination issues.
