Application of PVC Tin Stabilizers

Suggestions In The Use Of Methyl Tin Mercaptide Stabilizer:

1:PVC Calendaring Molding

CS-181 has excellent early whiteness, mid and long-term color stability and transparency in hard PVC sheet or rigid film. Because of the general lubricity, the lubricant type and amount should be carefully adjusted to have a direct impact on the quality of the sheet.

The amount of methyl tin stabilizer in calendering is 0.8~1.5 PHR

2:?Extrusion Molding

In rigid extrusion, CS-181 is mainly used in all kinds of transparent bottle pellets and tooling; it can also be used in high-grade window and door profiles, pipes and other architectural profiles.

If you are using in the extrusion of blowing PVC shrink film, you should choose the more low-cost and efficient composite methyl tin CST-181, product details please visit the website link, not too much explanation here.

Some methyl tin mercaptide dosage suggestions:

Rigid extrusion doors and windows: 0.8~1.2 PHR

Soft extrusion granulation: 0.5~1 PHR

CST-181 for printing shrink film: 1.8?PHR

CST-181-F for packing shrink film:1.3~1.6 PHR

3:?Injection molding

Rigid injection molding is one of the important applications of methyltin, due to its high efficiency and low addition level. It minimizes the negative impact of liquid stabilizers on the mechanical properties and Vicat softening point of the product.

Rigid injection fittings: 1~2?PHR
