Su Zhou Well Electric Co., Ltd. is based in China and lists Vulcanized Fiber (fish Paper) Tube and Vulcanized Fiber Sheets on Global Trade Plaza. The company lists its year of establishment as 2010. The Vulcanized Fiber (fish Paper) Tube is produced from a cotton rag base paper, forming a dense material of partially regenerated cellulose with retained fibre structure. It is used in electrical fuses, cut-out fuses, arc extinguishing, fuses, and circuit breakers, and is also known as vulcanized fiber bushing or motor shaft spacer. Available in grey or red, with customizable size and color options per customer requirements. The Vulcanized Fiber Sheets are made from multiple plies of paper, with thickness determined by the number of plies. The plies are treated in a zinc chloride bath, which makes the fiber surfaces gummy and sticky before being pressed together. The sheets are derived from pure first-grade cotton cellulose (non-wood pulp) processed with zinc chloride (vulcanized).
