1. Excellent Thermal Stability:

In the aspect of thermal stability,now there is no PVC heat stabilizers can exceed it.It owns excellent high temperature color stability and long term dynamic stability. Therefore, it is the first choice for rigid PVC and also suitable for all kinds of PVC homopolymers, such as emulsion, suspension and bulk PVC and PVC copolymers, graft polymer and the copolymer.

2. Excellent Transparency:

Organic Tin heat stabilizer has excellent transparency, especially the Methyltin Mercaptide stabilizer,after using it you can obtain crystalline products without whitening phenomenon. For this reason, LX-181 can be used for bottles, containers, bellows, various types of rigid packages and hoses, profiles, films ,etc.



Methyltin Mercaptide is non-toxic environmental friendly stabilizer and migrates minimally in PVC.It has been approved by the German Federal Health Agency, the US Food and Drug Administration(FDA),the British Plastics Federation (BPF) and Japan PVC Health Association (JHPA).Therefore,in these countries,Methyltin Mercaptide stabilizer is approved to use in food and pharmaceutical PVC packages and water pipes products.

4.Good Compatibility:

The Methyltin Mercaptide stabilizer has a good compatibility with PVC, and easily dispersed in PVC mixtures.It will not precipitate during long-term use. Therefore, it does not affect the surface properties and electrical properties of the PVC products. Especially,Methyl tin owns better compatibility with PVC than Butyltin and Octyltin.

5. Good Fluidity:

Methyltin Mercaptide stabilizer could improve PVC melting to gain a good fluidity in the PVC processing.In the aspect of resin plastification,compared with mixed metal or lead salt stabilizer, it generates lower melt viscosity, so that methyl tin is the best stabilizer choice for rigid PVC products.

6.Good Fluidity Resistance:

No fouling occurs after using Methyltin Mercaptide stabilizer,which will reduce cleaning times and production costs,also will improve production efficiency and expand profits.
