Temperature & Rubber Performance

  • 1. NBR (Nitrile Rubber)

    • Working Temperature: -30°C to +120°C

    • High Temperature Effects:

      • Above 120°C, acrylonitrile groups degrade, causing hardening, brittleness, and reduced abrasion resistance.

      • Prolonged exposure (>150°C) leads to molecular chain breakage, swelling, or delamination.

    • Low Temperature Effects:

      • Below -30°C, crystallization occurs, resulting in loss of elasticity and crack formation.

    2. EPDM (Ethylene Propylene Diene Monomer)

    • Working Temperature: -50°C to +150°C

    • High Temperature Effects:

      • Exceeding 150°C causes C-C bond fractures, increasing permanent deformation.

      • Accelerated oxidation leads to surface cracking.

    • Low Temperature Effects:

      • Below -50°C, molecular chains freeze, significantly reducing impact resistance.

    3. FKM (Fluoroelastomer)

    • Working Temperature: -20°C to +200°C

    • High Temperature Effects:

      • Above 200°C, Si-O bonds decompose, reducing chemical resistance.

      • Excessive heat causes scorching and bubble formation.

    • Low Temperature Effects:

      • Below -20°C, elastic modulus rises sharply, compromising sealing performance.

    4. Nylon Rubber

    • Working Temperature: -40°C to +100°C

    • High Temperature Effects:

      • Above 100°C, amide bonds hydrolyze, reducing strength by >50%.

    • Low Temperature Effects:

      • Below -40°C, increased chain rigidity causes brittleness and fractures.

    5. PVC (Polyvinyl Chloride)

    • Working Temperature: -10°C to +60°C

    • High Temperature Effects:

      • Above 60°C, plasticizer migration leads to brittleness.

    • Low Temperature Effects:

      • Below -10°C, glass transition occurs, eliminating impact resistance.

    6. PP (Polypropylene)

    • Working Temperature: 0°C to +100°C

    • High Temperature Effects:

      • Exceeding 100°C reduces crystallinity, increasing creep.

    • Low Temperature Effects:

      • Below 0°C, brittleness rises, promoting stress cracks.

    7. PA66 (Nylon 66)

    • Working Temperature: -40°C to +120°C

    • High Temperature Effects:

      • Above 120°C, water absorption increases, degrading dimensional stability.

    • Low Temperature Effects:

      • Below -40°C, toughness declines, enhancing notch sensitivity.

    8. ABS (Acrylonitrile Butadiene Styrene)

    • Working Temperature: -20°C to +80°C

    • High Temperature Effects:

      • Above 80°C, butadiene phase softens, reducing impact resistance.

    • Low Temperature Effects:

      • Below -20°C, styrene phase becomes brittle, prone to fractures.
