Phenolic Resin for Grinding Wheel Sandpaper

After years of technical accumulation and breakthroughs, our company has optimized its products to have better high temperature resistance and friction material formulation adaptability, and realizes a diversified layout of series products, and responds to different types of requirements through changes in indicators. The amount, formula and process of friction materials supply customers more choices, reduce the scrap rate, and at the same time ensure the superior performance of the product and effectively reduce the production cost.

Characteristics of phenolic resin

1) High temperature performance: The most important feature of phenolic resin is high temperature resistance, which can maintain its structural integrity and dimensional stability even at very high temperatures. Because of this, phenolic resins are used in some high-temperature fields, such as refractory materials, friction materials, adhesives and foundry industries.

2) Adhesive strength: An important application area of phenolic resin is the adhesive. Phenolic resin is a kind of multifunctional, compatible with various organic and inorganic fillers. The properly designed phenolic resin has a very fast wetting speed and can provide the required mechanical, thermal and electrical properties for grinding wheels, friction materials, wood blends and bakelite powder after crosslinking.

3) Low smoke and low toxicity: When encountering fire, the phenolic resin system produced by the correct formula can produce hydrogen, hydrocarbon water vapor and carbon dioxide during their slow decomposition process. The smoke produced in the process is relatively low and has relatively low toxicity.

4) High residual carbon rate: When the temperature is about 1000℃, the phenolic resin will produce very high residual carbon. This high residual carbon rate maintains the structural stability of the phenolic resin.
