Ancient Egypt, Greece and Rome used it to make fishing nets, floats, insoles, corks, etc. Cork has been recorded in the Spring and Autumn period of China. The main tree species that produce cork are cork oak and cork oak.

This structure makes cork veneer have very good elasticity, sealing, heat insulation, sound insulation, electrical insulation and friction resistance, plus non-toxic, tasteless, small specific gravity, soft touch, not easy to catch fire and other advantages, so far there is still no man-made product comparable to it. In terms of chemical properties, a mixture of esters formed by several hydroxyl fatty acids and phenolic acids is a characteristic component of cork, collectively known as cork resin.

This kind of substance is resistant to decay and chemical attack, so in addition to the corrosion of concentrated nitric acid, concentrated sulfuric acid, chlorine, iodine, etc., it has no chemical effect on water, grease, gasoline, organic acids, salts, esters, etc. It is widely used, such as bottle stoppers, insulation layers for refrigeration equipment, lifebuoys, sound insulation panels, etc.
