Material Description

Material Properties:

• Hardness: 70–90 Shore A (depending on application)

• Tensile Strength: ≥ 15 MPa

• Elongation at Break: 300–450%

• Chemical Resistance: Resistant to acids, alkalis, and organic solvents

• Temperature Range: -20°C to 200°C

Performance Testing

1. Abrasion Resistance Test

• O-rings are subjected to repeated friction cycles to evaluate wear tolerance.

• Test ensures that material loss is minimal over extended production periods.

2. Compression Set Test

• Measures the O-ring’s ability to retain shape under continuous pressure.

• Ensures long-term sealing efficiency in high-speed nonwoven lines.

3. Chemical Resistance Test

• Exposes O-rings to common industrial chemicals and solvents.

• Confirms no swelling, cracking, or degradation occurs during normal operations.

4. Thermal Stability Test

• O-rings are tested under high-temperature conditions to assess structural integrity.

• Ensures continuous performance in environments up to 200°C.

Operating Instructions

Installation Guidelines

1. Inspect the O-ring for visible defects such as cracks, tears, or deformations.

2. Clean the filter housing or groove to remove dust, fibers, or residues.

3. Lubricate the O-ring with a compatible lubricant if necessary.

4. Insert the O-ring into the housing groove, ensuring uniform contact along the circumference.

5. Secure the filter assembly without over-tightening, which could deform the O-ring.

6. Run a short test cycle to ensure proper sealing and airflow.

Maintenance Recommendations

• Weekly Inspection: Check for signs of wear or misalignment.

• Monthly Cleaning: Use compressed air or soft brushes to remove fiber dust.

• Quarterly Replacement Check: Ensure the O-ring maintains its original dimensions and elasticity.

Applications in Nonwoven Fabric Industry

The High Wear-Resistant Filter O-Ring is suitable for various nonwoven fabric production lines:

• Spunbond Lines: Ensures stable airflow and uniform fabric thickness.

• Meltblown Lines: Prevents leakage in high-temperature filtration systems.

• Needle-Punched Lines: Maintains airtight sealing under continuous vibration and movement.

• Carding and Web-Forming Machines: Reduces downtime and improves operational reliability.

Benefits for Nonwoven Manufacturers
