and Phenolic Molding Compounds Greg Spaeth Project Engineer Materials Engineering Laboratory Plastics Engineering Company Presented at 2013 SPE Thermoset Division TOPCON Phenolic Resins Phenolic resins are synthesized in a pressure vessel by repeatedly linking phenolic monomers with aldehyde chemicals. Composite materials. are made from two or more constituent materials with significantly different physical. . or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure.. 1 Phenolic Ethers Alkyl Phenolics Heterocyclic Ethers Larger PAH 500 600 700 800 900 Figure 1 Formation of biomass tars and example of compounds formed Research was initiated to measure antioxidant activity of extracts fromoat (Avena sativa L.) groats and hulls and the concentrations of phenolicsubstances that may contribute to antioxidant activity. 1.

Phenolic resins are obtained by the reaction of phenols with aldehydes. Both parent compounds, phenol and formaldehyde, are by far the most important components in commercial phenolic resin production .
