Phenolic NP629 Sheet – High-Performance Laminated Paper for Mechanical & Electrical Use

NP629 is a paper-phenolic high-pressure laminate and intended primarily for mechanical applications, but is suitable for electrical applications as well. The electrical properties are not quite as good as those of NP630.
