EA-5820J

Color:Black

1. Characteristic and usage：

The product is a thermosetting molding compound, it is based on phenolic resin as a matrix and mixed with organic fiber and mineral filler and other additives. It is suitable for injection molding and easy process. It has excellent properties of flame resistance and electric insulation, meanwhile it also has good mechanical property, waterproof, tracking resistance and dimensional stability. It is mainly used for making insulating structural parts that has flame resistance. The appearance of the product is the powder with granules.

Note:The indexes of fluidity (Raschig) and shrinkage are determined by the seller and buyer, they are only for reference.

3.Moulding condition for testing sample

Preheating Condition		Curing Condition
Temperature	Time	Temperature	Pressure	Curing Time
°C	min	°C	MPa	min/mm
105-125	10-20	165-175	25-40	1.0

Note:After sample is preheated, it should be kept in mould for 20-40s and then breathing, the pressure is added at last.

85-90	75-85	165-175	170-180	80-160	100-200	20-30

5. Package and storage：

The products should be packed in moisture-proof liner bags to keep dry; the net weight of product is 25kgs. On bag, the type, batch number, weight and manufacture date of product should be marked.

The products should be prevented from moisture and heat. They should be stored in cool and dry warehouse. They should be kept away form fire, warm air and sunlight. The product storage life is one year. If the products are out of the storage limit, another tests should be done, and then the qualified products still can be used.
