Melamine composite paper sheets has high mechanical properties, excellent electric trace resistance and arc resistance. This board is made by impregnating cellulose fiber paper with modified phenolic resin and laminating it with a melamine surface through hot pressing. It is applicable for motors and electrical equipment with high requirements for arc extinguishing performance as insulating structural parts.
FAQ
FAQ
Q: What are the advantages of melamine composite paper laminate compared to ordinary insulating boards?
A: Melamine composite paper laminate performs exceptionally well in arc resistance and tracking resistance, with good mechanical strength and processing properties. Ordinary insulating boards may have deficiencies in arc-extinguishing performance or mechanical stability, whereas this product can better meet the needs of electrical equipment with high requirements for arc-extinguishing performance.
Q: What is the temperature resistance rating of the product? Can it be used in high-temperature environments for extended periods?
A: The product has a temperature resistance rating of Class B (long-term use temperature ≤130°C) and can be used stably for extended periods below 130°C. Beyond this temperature, the product's performance may gradually decline, so long-term use in high-temperature environments is not recommended.
