Firstly i think we should know its operation principle.
One pack Ca/Zn stabilizer Theory:
1. Zinc-salt replace unstable chlorine.
2. It can absorb the HCL caused by decomposition.
Auxiliary stabilizer: Zeolite, hydrotalcite, &-diketone
3. Chelation ZNCL2

So what's the general components for one pack Ca/Zn stabilizer ?

1. Organic calcium salts: calcium fatty acids and calcium aromatic acids
2. Organic zinc salt:
3. Auxiliary PVC stabilizer
4. Antioxidant: 1076,1010,168, etc. without Lead salt.
5. Internal and external lubricants
Lubricants have an important effect on the overall formulation system.
Then i think you have the answer for above question already.
