Cost Effective Thermal Stabilization Performance Enhancement of PVC with Magnesium Aluminum Carbonate Additives

Product Name: Hydrotalcite adsorbent

CAS No.: 12304-65-3

Molecular Formula: [M_(1-X)²⁺M_x³⁺y(OH)]^x+(A^n-)_x/n·mH₂O

Product Introduction:

        Magnesium Aluminum Carbonate, these cost effective additives significantly enhance PVC's resistance to heat-induced degradation. In thermal aging tests at 180°C, PVC samples without our additives started to show signs of discoloration and mechanical property decline within 30 minutes. However, when our magnesium aluminum carbonate additives were incorporated at a 3% weight ratio, the samples remained stable for over 120 minutes, with a 4-fold increase in the time to initial degradation. By efficiently scavenging the harmful HCl generated during PVC processing, they prevent premature aging and maintain product quality. With a lower price point compared to many alternatives, they offer an economical solution for PVC manufacturers aiming to improve thermal stabilization performance without breaking the bank.

Specification:

Advantages of Magnesium Aluminum Carbonate in PVC application:

1.Efficient thermal stability:

It can effectively capture the hydrogen chloride generated by the thermal decomposition of PVC during processing and use, delay the degradation rate of PVC, increase the thermal decomposition temperature of PVC, and enable PVC products to maintain stable performance at higher temperatures, reducing problems such as discoloration and mechanical performance degradation.

2.Combining other functions:

In addition to thermal stability, it also has a certain degree of flame retardancy, which can improve the fire resistance of PVC products; At the same time, it can also improve the weather resistance of PVC, enhance its ability to resist environmental factors such as ultraviolet radiation and oxygen erosion, and extend the service life of PVC products.
3.High cost-effectiveness:

With a relatively wide range of sources and continuous optimization of production processes, the cost gradually decreases. While providing good thermal stability, it has a high cost-effectiveness, which can reduce production costs and improve economic benefits for PVC production enterprises.
