Footnotes:

  1. (A) is Category A, (C) is Category C in the IEC 60332 standard
  2. The density and hardness will be fixed when we get the requirements from each customer
  3. The property can be adjusted to be higher than the value in the standard if customer requires
  4. Phthalate-free grades or other standards are available upon request
  5. Lead-based grades are available upon request
  6. Anti-termite or/and anti-rodent property is available upon request
  7. We have grades to meet the requirements of fire-resistant cables under UL 1581
