what is vulcanized?

Vulcanized is a chemical process that involves the addition of sulfur and other chemicals to a material, such as rubber or cellulose fibers, in order to increase its strength, durability, and other desirable properties.
During vulcanized, the material is heated and pressurized, causing the sulfur to react with the molecules in the material and form cross-links between them. This process creates a material that is much stronger and more durable than the original, unvulcanized material.
The process of vulcanization was first discovered by Charles Goodyear in the mid-19th century, and has since become widely used in the production of various industrial and consumer products, including tires, electrical insulation, gaskets, and even some types of clothing.
The raw material for vulcanized fiber  paper is cellulose fiber. This can be obtained from a variety of sources, including wood pulp, cotton, and other plant-based materials. The cellulose fibers are typically processed and refined to remove impurities and create a uniform material that is suitable for vulcanization.

Once the cellulose fiber  have been prepared, they are subjected to a series of chemical treatments that are designed to make them more resistant to heat, chemicals, and other environmental factors. This typically involves the addition of sulfur and other chemicals, which cross-link the cellulose fibers and create a stronger, more durable material.

After the chemical treatments have been applied, the cellulose fiber  are compressed under heat and pressure to create sheets or rolls of vulcanized fiber. The thickness and other properties of the material can be adjusted by varying the amount of pressure and heat that is applied during the Vulcanized process.
