how to distinguish good plasticizer

Resin has good compatibility , compatibility is insufficient, the pneumatic tube plasticizer separated from the resin , the performance of exudation, sweating phenomenon. Pneumatic tubes zinc stearate  incompatible with the resin plasticizer , plasticizing efficiency of the question.
Plasticizer variety, then have what conditions it can be called a good plasticizer , today teach you the recipe :
1 . High plasticizing efficiency , with less to obtain a higher amount of added plasticizing effect .
2 . Good compatibility with resin , compatibility is insufficient, the pneumatic tube plasticizer separated from the  chromium oxide resin , the performance of exudation, sweating phenomenon. Pneumatic tubes incompatible with the resin plasticizer , plasticizing efficiency of the question.
3 . Low volatility, reduce and pneumatic tube forming volatile loss during storage for pneumatic tube performance. Car decoration , wire and cable and other areas have higher requirements for volatile . 4 . Durability , water , oil, organic solvent extraction .
5 . Do not migrate , pneumatic tube plasticizers are not supposed to come into contact with other solid medium diffusion .
6 . Cold, and requires the processing temperature is still good softness . This agricultural films and outdoor use  aluminium stearate pneumatic tubes is very important.
7 . Good heat resistance , requiring the use of higher processing temperatures and temperature stable .
8 . Non-toxic, tasteless , odorless and colorless.
9 . Good resistance to fungal
10 . Flame retardant
11 . Good electrical insulation
12 stain resistance, chemical etching
13 . When the plastisol is used , requires that the preparation of the plastisol viscosity stability is good.
