Ca-zn YS-59

YS-59 is a special calcium zinc stabilizer developed for high speed extrusion and high filling of PVC. It consists of calcium salt, zinc salt, lubricant and antioxidant as main raw materials, and is a processing raw material additive synthesized by special composite process.

Product introduction
Application

Used in the processing fields of PVC profiles, pipes, plates, and wood plastic foams.

Storage

Stored in a cool and dry warehouse, and avoid rain and damp. Keep away from fire and heat source during storage. Avoid exposure to the sun, and prohibit direct contact with acid and alkali or mixed storage.

Packaging

25kg/ bags.

Features
  • No heavy metal elements(lead). Comply with EU environmental protection standard RHOS
  • Resistance to sulfide contamination: In the field of PVC door and window profiles, the products using composite lead heat stabilizers are easy to be contaminated with sulfur and tin, resulting in blackening, while calcium zinc stabilizers are not affected by this
  • Good system switching characteristics : It can directly replace lead salts and organotin stabilizers. The traditional composite lead heat stabilizers can be converted into organotin stabilizers, resulting in cross contamination and blackening of products. Calcium zinc stabilizers can not be switched and mixed at will.
  • High cost performance: It has good lubricity and unique coupling effect, improves product performance, reduces mechanical wear and extends the service life of the equipment. Due to its balanced lubrication, it is not easy to precipitate and has long production cycle.
