Tin thermal stabilizers are products used by PVC manufacturers across various industries to delay the thermal degradation of the material during processing at high temperatures. Hydrogen chloride (HCl), released by PVC in gaseous form, acts as a catalyst in the thermal degradation process. Proper dosing helps prevent surface yellowing and promotes achieving the desired finished product. In addition, tin thermal stabilizers provide excellent initial color, gloss, and transparency, making them one of the most preferred solutions in the market.
Tin thermal stabilizers naturally have a certain odor, which can be controlled by reducing their dosage and/or by using them in combination with other co-stabilizers that together help prevent thermal degradation. Due to their high performance, they are commonly preferred for rigid PVC and in processes involving high compression, such as injection and extrusion.
For outdoor applications, special grades are available, as conventional methyltin is weak under sunlight exposure, since it promotes the formation of chromophores. However, this effect can be mitigated through the addition of other additives.
Although its unit cost may be higher compared to other alternatives, it is usually selected due to its excellent cost–benefit ratio and its easy integration into the PVC matrix during the mixing process.
It is one of the most widely used tins on the market due to its excellent performance relative to its cost, and it also provides good transparency, making it suitable for both transparent and opaque applications. It is commonly used in rigid products for extrusion, calendering, and injection molding processes of all kinds. We offer grades with varying tin content.
They are the tin thermal stabilizers that the PVC pipe manufacturers They are used. They are tailored precisely to the needs of these manufacturers, where the key is to minimize the cost-benefit ratio to maximize profits while maintaining peak productivity. Their tin content is lower than that of other types of stabilizers. methyl tin But it is more than enough for what is required.
It's a type of tin thermal stabilizer guy octyl, which is the preferred alternative for use in medical and/or food products. It has FDA approval in terms of toxicity. Its tin content is lower than that of conventional methyltin, however, it has sufficient yield for processing PVC.
