Usage and Dosage:

Jointly used with polyester plasticizers, it can reduce their mobility, while with metal heat stabilizers, it would greatly enhance their stability, and the dosage of these metal stabilizers necessary can be reduced to only one third of that used alone. As far as compatibility with PVC, ESO is equivalent to DOP and is better in terms of plasticizing efficiency. Thus the total need of plasticizers would be less. It does not only bring down the cost, but also improves the technical standard of our products, such as the tolerance of impact, transparency, printability, weld ability and so on. 5~10 portion of ESO would remarkably ameliorate the heat and light stability of soft products. Under special situation, 10~30 portion of ESO used non-open-air, no other stabilizers is necessary. The addition of this chemical, will cut down the amount of other plasticizers, stabilizers and lubricants needed.
