How to Choose High Tem Resistant Sleeving for Automotive Wiring

1.Key Challenges in Automotive Wiring Protection

Automotive wiring faces extreme conditions:

  • Engine Compartment Heat: Up to 200°C+ near exhaust systems
  • Abrasion Risks: Vibration against metal parts requires sleeves with ≥500,000 flex cycles
  • Chemical Exposure: Oil, coolant, and acid resistance
  • Flammability Standards: Must meet IATF16949 + UL94V0

3. Step-by-Step Selection Process

Step 1: Define Thermal Requirements

  • Underhood: Choose 260°C+ rated sleeves
  • EV Battery: 150°C with flame retardancy

Step 2: Verify Material Composition

  • Avoid PVC (deforms at >105°C)

Step 3: Check Industry Certifications

  • Must-have: IATF16949
  • Value-add: UL Cetified + EN45545

Step 4: Test Physical Durability

  • Abrasion test videos
  • 3rd-party flammability reports

4. Why MJ-Flex Outperforms?

  • Automotive Focus: IATF16949
  • Eco Advantage: 100% recyclable PET
