How Are Phenolic Resins Produced?
Phenolic resins are made from phenols and aldehydes. A condensation reaction occurs when a catalyst is added, and phenolic resins are produced.
Depending on the method of heating and the mixing ratio, resole or novolac phenolic resins are created.
Resoles are basically liquid at ambient temperatures, but they harden when heated and do not turn back into liquid form.
Novolacs are normally solid. They melt when heated and resolidify when cooled to an ambient temperature.
We take advantage of their respective characteristics; resoles are used for applications such as insulation material, and novolacs are used for casting and in the manufacturing of electronic materials.
How Are Phenolic Resin Products Made?
Making phenolic resin products is similar to making cakes and desserts.
Phenolic resins are mixed with hardening materials and additives.
The product created depends on the ratio of additives that was used.
It’s just like whether you make a cake or a custard depends on the amount and combination of ingredients such as flour, milk, and eggs, isn’t it?
Byproducts generated during the manufacturing process are not discarded but returned to the earth in a form that is useful to nature.
We are also actively working on environmental measures, such as recycling used insulation materials into energy sources.
