Important Index Of Phenolic Resin


High-temperature performance

The most important feature of pultruded phenolic resin is high-temperature resistance, stability even at very high temperatures, it can maintain their structural integrity and size. For this reason, the phenolic resin is generally used in the high-temperature fields, such as refractory material, friction material, binder and foundry industry.

The bond strength

An important application field of phenolic resin is binder. Pultruded Phenolic resin is a kind of multi function, and a variety of organic and inorganic filler can compatible material. Phenolic resin wetting speed particularly fast and correct design of friction material for grinding wheel, after cross-linking, wood powder mixture and provide the required mechanical, thermal and electrical properties.

Water-soluble phenolic resin is used to impregnated paper, cloth, glass, asbestos and other similar material to provide mechanical strength, thermal properties and the filtration capacity. Typical examples include the electrical and mechanical clutch and laminated, automotive oil filter.

Resistance to chemical reaction

Crosslinking phenolic resin nature means he can resist decomposition of any chemical substances. For example, gasoline, oil, alcohol, ethylene glycol and other hydrocarbon compounds.

Low smoke, low toxicity

Properties of phenolic resin low smoke and low toxic and made him very strict requirements in the transportation and the use of regional advantages, such as mining, public buildings and protection device. In the case of fire, the correct formula to produce phenolic resin system can produce hydrogen in their slow decomposition of hydrocarbons, water vapor and carbon dioxide. In the process of smokeless toxicity is relatively low.

High carbon residue rate

At a temperature of about 1000C, phenolic resin will have high residual carbon, which maintains the structural stability of phenolic resin. The properties of phenolic resin and can be used for an important reason for the refractories.
