3240 epoxy resin fiberglass cloth laminated sheet

The surface of 3240 epoxy resin fiberglass cloth laminated sheet should be smooth, without bubbles, pits or wrinkles, but other defects which won’t affect the use can exist, such as: scratches, dents, stains, and a few spots. The edges should be cut neatly, and there can’t be any delamination or cracks in the side.

Standard: GB/T1303.1-1998 (natural color), also can be black, red and green. The product has excellent mechanical properties, has high mechanical strength in middle temperature, and high humidity electrical properties stability in high temperature.

Application: can be used for electrical, electronic, electrical and mechanical fields, suitable for

the insulation machined parts, can be machined into various types of insulation accessories and equipment insulation parts.

3640 epoxy resin fiberglass cloth laminated tube

3640 epoxy resin fiberglass cloth laminated tube is made of non-alkali fiberglass cloth impregnated with epoxy phenolic resin.

Its surface should be smooth, can’t have any bubbles, slight wrinkle can exist in the inner wall.

Ends should be cut neatly.

This kind of products has high mechanical properties, heat resistance and dielectric properties, can be used in electrical machines as insulation structure parts in the wet conditions or in transformer oil. 3640 is one of the most needed products in the market, also widely used.

Min ID: 4 mm   Max OD: 1000 mm.

XU-380 phenolic cotton cloth laminated tube

380 Phenolic cotton cloth laminated tube is made of cotton cloth impregnated with phenolic resin.

It has a high radial tensile strength, it’s a traditional insulation materials, its inside and outside surfaces should be free of lattices, ends should not have cracks, delamination, the ends need to be cut neatly.

Standard: GB/T5132.  Density:≥1.2 g/cm³  Radial tensile strength≥50Mpa.

Since the tube has an unique self-lubricating property, it can be used for many other fields, not only insulation, such as resistant materials, or the cage for the high speed bearings.
