<Anticorrosion vinyl tape>

No.51 Outline Anticorrosion vinyl tape NO.51 Developed for prevention of corrosion and protection of various types

of pipelines. Using vinyl chloride with excellent electrical property and chemical resistance as base material together with thick- coated synthetic rubber-base adhesive, it brings out superior durability and anticorrosion property. Being highly flexible, it is easy to wind and suitable for work in temperature and for work on joint or flexural area.
