Poly Vinyl Chloride Stabilizers Requiring an Environmentally Consciousness
Poly vinyl chloride (PVC) are used for a variety of purposes, in everything from rigid products like pipes and window profiles to flexible products such as electrical cables and wrapping film.
Stabilizers are what provide these PVC products with their mold stability and durability. The main ingredient within stabilizers is metallic salts, which are separately utilized according to the uses for PVC.
Lead compounds, which are classified as harmful heavy metals, have been used for many years in things like rigid items such as pipes and window profiles, as well as wire covering and more. However, there is a growing international trend toward avoiding lead compounds due to concerns that they affect the human body and pollute the environment.

Technology that Avoids the Use of Lead Compounds and Contributes to Environmentally Consciousness for PVC Products
ADEKA has been a world leader in developing environmentally conscious wire coating extrusion stabilizers to be substituted for lead compounds, and our environmentally conscious stabilizers are among the top share of automotive electrical cables. We are also contributing to electrical cable for consumer electronics and communications, as well as stabilizers for rigid items like window profiles.
For the future it is indispensable that environmentally conscious stabilizers expand in conjunction with this. ADEKA will contribute to environmental consciousness in global markets by utilizing the technology and global networks that we possess.
