Hydrotalcite is an inorganic compound and a good acid absorber, which can effectively inhibit zinc combustion during processing. It is suitable for the addition of Ba / Zn system and Ca / Zn system formula. When the hard formula of Ca / Zn system is applied, its unique effect is more obvious, and it still has good thermal stability at high temperature of 400 ℃.

Hydrotalcite has excellent thermal stability, that is, hydrotalcite can improve the thermal stability of PVC mixture, and the effect is very significant; we say that hydrotalcite has excellent transparency, that is, hydrotalcite can make PVC products transparent, and the transparency is very high. Hydrotalcite is a non-toxic thermosetting curing agent, stabilizer, catalyst, filler, PVC and other plastics LDH, which is applied to polyolefin. The refractive index of hydrotalcite and polymer is similar, so it has good transparency, mg / Al, harmless to human body, and good thermal stability.
