Customized Flake Novolac Phenolic Resin P2324 Flame Resistance For Impregnating Glass - China

Flake Phenolic Novolac Resin P2324 for Impregnating Glass Cloth in Cutting Wheels Product description In cutting wheels and depressed center wheels, glass cloth is used to reinforce the wheel.

These are referred to as reinforced grinding wheels.

The glass cloth used for reinforcing the wheel is impregnated with phenolic resin.

The procedure for coating this glass cloth is as follows: The glass cloth is dipped in liquid phenolic resin, dried at 80100 C for 310 min, and after drying, is cut to the size of the wheel.

The amount of the wet impregnated resin on the glass cloth is controlled from 30 to 50%.

The phenolic resin for this impregnation is mainly a resin consisting of a resole mixed with a novolac.

Phenolic resin is designed such that the glass cloth is not tacky when stored and the adhesion is increased between phenolic resin and the grain.

The strength of glass cloth determines rotational strength.

Therefore, the fabric strength and the type of weave are important.

This effect demonstrates the safe rotational speed of a glass reinforced wheel of 4, 500 m/min verses 3, 000 m/min for a wheel without glass cloth reinforcement Flake Phenolic Resin P2324 for Impregnating Glass Cloth areare produced by reacting formaldehyde with phenol under acidconditions with low free phenol and narrow MWD(Molecular weight distribution ).

It is novolac resin and crashinto flakes.
