At TMG-Chemicals, we offer various Tin maleate products that stabilize the heat during the PVC
polymerization reactions and improve the final products' properties and performance according to their
intended use. These Tin maleate stabilizers are sulfur-free and highly recommended for PVC products that
require excellent transparency, thermal stability, and weatherability.

Polyvinyl chloride (PVC) is the third most common synthesized plastic polymer after polypropylene and
polyethylene. PVC has gained widespread popularity due to its exceptional versatility, durability and costeffectiveness.
This thermoplastic material can be rigid or flexible, making it suitable for various applications
across different industries. PVC is known for its excellent chemical resistance, electrical insulation and flameretardant
properties, making it a preferred choice in manufacturing products such as pipes, cables, window
profiles, medical tubing, automotive parts and more.
A tin stabilizer is made of an organotin mercaptide or carboxylate compound, commonly used for PVC heat
stabilization. They offer enhanced transparency, thermal stability, color retention, and workability. It has
several single and di alkyl salts combined in different ratios. The stabilizers essentially offer protection against
heat damage during PVC processing.
Tin maleates are sulfur-free organotin carboxylates that provide excellent light stability to finished goods
intended for outdoor applications. However, they are less efficient as heat stabilizers than the sulfurcontaining
organotin mercaptides.
TMG-Chemicals offers a selection of eight distinct butyl and octyl tin maleate heat stabilizers, which are
extensively employed in PVC resin production. These heat stabilizers exhibit notable potential and are tailored
to specific applications, each with its anticipated performance. To facilitate the decision-making process, the
intended use and expected performance of each tin maleate heat stabilizer are presented in the table below.

KEYNOTES
Tin maleate heat stabilizers
* Tin maleates offer several features: Improved transparency, Thermal stability, and Color retention.
* TMG-234 is recommended for PVC/ABS, excellent light stability, and odorless application.
* TMG-314 LC, 317 LC, 318 LC, and 326 are recommended for food grade films and blister packaging.
* TMG-326 is effective as a heat stabilizer in plastics and thus enables longer product life cycles.
*No sulfur contents; no more smell issues during the production process in the plants.
