Alcohol Rubber Abrasion Testing
Alcohol rubber abrasion testing is a durability test used to evaluate the wear resistance of printed, painted, or coated surfaces on telecom, automotive, and electronic products. The test involves rubbing a surface with a rubber pad soaked in alcohol under controlled force and repetitions to assess the resistance of markings, coatings, or labels. This method ensures that markings such as logos, symbols, and text on telecom products remain legible and do not fade due to frequent handling, alcohol cleaning, or environmental exposure.
Major Technical Specifications of Alcohol Rubber Abrasion Testing
The key parameters defining this test include:
1. Test Material – Commonly applied to coatings, prints, and markings on telecom, electronics, and industrial components.
2. Test Agent – Uses isopropyl alcohol or ethanol (depending on standards or customer requirements).
3. Abrasion Tool – A rubber eraser, rubber stylus, or specified rubbing material.
4. Rubbing Force – Typically ranges between 1N to 5N (Newton).
5. Rub Cycle – Measured in the number of strokes (e.g., 50, 100, 200 cycles.
6. Speed of Rubbing – Generally 30 to 60 strokes per minute.
7. Test Conditions – Controlled temperature and humidity conditions.
8. Evaluation Criteria – Pass/fail based on visible damage, fading, or detachment of the marking.
