High definition Smc Sheet - GPO-3 (UPGM203) Unsaturated Polyester Glass Mat Laminated Sheet – D&F

GPO-3 Molded Sheet (also called GPO3,UPGM203) consists of alkali–free glass mat impregnated and bonded with the unsaturated polyester resin, and laminated under high temperature and high pressure in mould. It has good machinability, high mechanical strength, good dielectric properties, excellent proof tracking resistance and arc resistance. It is with UL certification and passed the test of REACH and RoHS, etc. It is also called as GPO-3  or GPO3 sheet,GPO-3 or GPO3 insulation board.

It is applicable for making insulation structural and supportive components or parts in F-class electric motors, transformers, switch gears, circuit breakers and electrical equipment. The UPGM can be directly molded into different profiles or insulation structural parts.

Thickness range：2mm—60mm

Sheet size：1020mm *2010mm, 1000mm*2000mm, 1220mm*2440mm and other negotiated thickness or/and sizes

Main color: red, white or other negotiated colors

Besides the UPGM laminated sheets, we also produce and supply the EPGM 203 sheets, the sheet dimension are the same as those of GPO-3. The color is yellowish or green. Please contact me for more information.

Technical Requirements

Appearance

Its surface shall be flat and smooth, free from blisters, wrinkles or cracks and reasonably free from other small imperfections such as scratches, dents and uneven colors.

Normal thickness and tolerance

Physical, mechanical and electrical properties

Inspection, Mark, Packaging  and Storage

1) Each batch should be tested before dispatch. The inspection items for Routine Test shall include Clause 2.1,  2.2, and Item 1 and Item 3 of Table 6 in Clause 2.3. The items in Clause 2.1, 2.2, should be checked one by one.

2) The sheets shall be stored in a place where temperature is no higher than 40℃, and be placed horizontally on a bed plate with a height of 50mm or above. Keep away from fire, heat (heating apparatus) and direct sunshine. The storage life of sheets is 18 months from the date of leaving factory. If the storage duration is over 18 months, the product also could be used after being tested to be qualified.

Remarks and Precautions for Handling and Use

1)A high speed and small depth of cutting shall be applied when machining because of sheets’ weak thermal conductivity.

2) Machining and cutting this product will release much dust and smoke. Suitable measures should be taken to ensure dust levels are within acceptable limits during operations. Local exhaust ventilation and use of suitable dust/particle masks is advised.
