Hydrotalcite FM300 Properties:

White powder, tasteless, non-toxic, non-flammable, 250℃ began to decompose. Water is insoluble but acid is soluble.


1. With other heat stabilizer, such as organic tin, or zinc salt as heat stabilizer, can further improve the thermal stability of PVC.

2. Can improve the flame retardant of PVC, inhibit the smoke when PVC burning, can also be used for all kinds of rubber, such as EPDM, NBR, etc., not only has good flame retardant, but also has reinforcing effect.

3. Use together with other auxiliaries to improve the light stability and weather resistance of PVC.

4. Promote the selective absorption of infrared light (wavelength 4.2μm) of PVC agricultural film, improve the thermal insulation property of agricultural film.

  • 5. It can improve the anti-fog droplet performance of agricultural film.
