Tin Stabilizer is an organotin-based heat stabilizer commonly used in transparent and semi-rigid PVC products. It provides excellent heat resistance, clarity, and low odor processing, especially in high-temperature or sensitive applications like medical tubing, food packaging, and transparent bottles.
Unlike metal soap stabilizers, tin stabilizers bond chemically with PVC chains, offering better protection against thermal degradation and discoloration during extrusion or calendaring.

Q1: Is Tin Stabilizer safe for food and medical applications?
Yes. Many grades meet FDA 21 CFR and European food contact regulations.
Q2: Can I use Tin Stabilizer in non-clear PVC?
Yes, though it’s most cost-effective in transparent or semi-transparent products.
Q3: What if I need a low-odor formulation?
We offer special grades with minimized smell, suitable for indoor or medical use.
Q4: Is it compatible with impact modifiers or plasticizers?
Yes. It works well with common modifiers like MBS, CPE, and DOTP.
Q5: Are there solid versions available?
Liquid is standard, but we also supply tin stabilizers in pre-dispersed masterbatch or paste form.
