    Product Description

    3240 Halogen-free fire retardant Epoxy phenolic glass fiber laminated sheet:This product is a laminated product made of electrical purposed alkali-free glass cloth impregnated with epoxy phenolic resin by hot pressing.The thermostablity is grade B.It has good mechanical and dielectrical properties,Applicable to mechanical, electrical, electronic, electrical and other fields. It is also used in the processing of insulating parts, and processed into all kinds of insulating parts and equipment insulating structural parts, which can be used in wet environment conditions and transformer oil.

    The more important is this 3240 laminate is Halogen-free and fire retardant,which is eco-friendly and can be acceptable by European and American markets.

    Compliance with standards:

    In accordance with GB/T 1303.4-2009 electrical thermosetting resin industrial hard laminates - Part 4: epoxy resin hard laminates, IEC 60893-3-2-2011 insulating materials - electrical thermosetting resin industrial hard laminates - Part 3-2 of the individual material specification EPGC201.
