Alsil is widely used in PVC production as a thermal stabilizer, preventing degradation of the polymer during processing and use. It also acts as an adsorbent, capturing acidic byproducts released during thermal degradation, prolonging the useful life of the material.

In combination with hydrated alumina, which improves mechanical strength and dimensional stability, Alsil provides a more durable and higher quality PVC.

Whitelum white pigment, based on alumina, is another important component, ensuring intense and uniform white coloring of PVC, in addition to increasing resistance to light and weathering. Together, these additives ensure superior performance and consistency in processing, resulting in final products of higher quality and durability.
