Frequently Asked Questions

Get answers to common questions about our insulation materials.

What is the heat resistance of your insulation tapes?

Most of our tapes, including the 6520/6521 series and acetate cloth tapes, are rated for E-class insulation (120°C). Special materials like NHN Nomex can withstand up to 220°C.

Are your products RoHS compliant?

Yes, all our electrical insulation tapes and materials meet RoHS criteria, ensuring they are free from hazardous substances.

Can I customize the thickness or size of insulation sheets?

Absolutely. We offer customized insulation pressboard, films, and composite materials in various thicknesses (e.g., 0.13mm–0.50mm) and dimensions to meet your specifications.

What is the difference between DMD and NHN insulation?

DMD (Polyester Film - Nonwoven - Polyester Film) is cost-effective and suitable for general motor insulation. NHN (NOMEX® Honeycomb) offers superior thermal and mechanical performance for high-temperature applications.
