As a widely used thermoplastic, PVC is widely used in many industries such as construction, packaging, wires and cables due to its excellent mechanical properties and processing properties. However, PVC is susceptible to degradation due to heat and light during processing and use, resulting in performance deterioration. Therefore, adding effective stabilizers has become the key to improving the quality of PVC and extending its service life.

Stabilization mechanism of butyltin mercaptide

Butyltin mercaptide is an efficient PVC stabilizer. Its mechanism of action is mainly reflected in the following aspects:

  2. Transparency: For transparent or translucent PVC products, tin butyl mercaptide can provide excellent transparency and will not cause fogging or discoloration like some metal soap stabilizers. .
  3. Compatibility: Tin butyl mercaptide has good compatibility with PVC and is easy to disperse in the PVC complex without affecting the surface properties and electrical properties of the product.
  4. Fluidity: Compared with other organotin stabilizers, butyltin mercaptide has better fluidity, which is beneficial to the flow of materials during PVC processing and improves processing efficiency.
  5. Synergistic effect: Tin butyl mercaptide can work synergistically with other stabilizers such as antioxidants and light stabilizers to jointly improve the overall performance of PVC.

Application cases

In rigid PVC products, such as pipes, profiles and plates, butyltin mercaptide is used as the main stabilizer or co-stabilizer, which can Significantly improves the thermal and color stability of products, especially under long-term outdoor use conditions.
