Product introduction
Pamica 5531 are rigid plate-shaped insulation materials produced through the process of baking and suppressing exceptional high-grade Pamica® mica paper or mica pieces, bonded with a certain amount of specially selected epoxy resin.
They are sanded on both sides resulting in uniform and precise tolerances. Other significant properties including bond content, compressibility, flexural strength, resistance to exudation, etc. are permanently controlled and documented. It exhibits good electrical properties, mechanical strength, excellent moisture resistance, and can be sawed, sheared and punched into intricate shapes. It also has superior uniformity, automatic feeding and stacking are possible for cost savings in high speed assembly operations.
