本产品是由白粉 云母纸，浸涂硅改性环氧树脂粘合剂，经 烘焙、热 压加工而成的硬 质板状绝缘材料。
本产品具有较高的机械强度和良好的厚度均匀性，并有优越的电气性能，在高温高压作用下又高的粘结强度和良好的抗冲击性，抗压碎性和耐弧性 ，以及好的整体性和冲剪性。
本产品耐热等级为H级，适用于工作温度180℃的H级直流电机换向器铜 片间绝缘，避雷器的阀片间绝缘和普通电热器
的绝缘垫片。
This product is made from gold powder mica saturated and coated epoxy polyimide resin adhesion agent through baking and heat pressing.
Ltis characterized by high mechanic intensity,even thickness and excellent electrical performance. Under the high temperature and pressure, it has high adhesive ntensity and sound impact resistance,compressive breaking strength and resistance to arc as good comprehensiveness and punching and shearing.
This product with heat resistance H-grades suitable for H- grade 180 directory current motor commutators insulation between coppers, insu ation between the common electric heating appliance.
