Resins used by GLOBE are produced only by European producers, selected over time for their reliability to supply high performance products and to keep the strict physical/chemical requirements necessary for manufacturing quality wheels.
Binding resin has the task to agglomerate abrasive grains and fiberglass reinforcements in a solid and strong body. The most used resins are phenolic in liquid and powder form. This type of resins has the important characteristic to give a high resistance to the heat developed during cutting or grinding. Phenolic resins are mixed with abrasives and additives in order to obtain a mixture, which is placed in the moulds of the hydraulic presses, and pressed at 200÷300kg/cm2. The product obtained is placed between the metal cooking plates and then sent to polymerization ovens where there is the irreversible formation of chemical bonds between molecules of phenolic resin, allowing to obtain a solid matrix and resistant to stress and high temperatures.
