The nature of the processing aid ACR for solid plasticizer. If the lower melting point of ACR, molecular weight fall again, will eventually become plasticizer. In the study found that low melting point of processing aid (including plasticizer) plasticizing speed, good melt flow, but low melt viscosity, low melt strength, melt pressure is low; High melting point of processing AIDS plasticizing rate slower, melt some illiquid, but the viscosity of molten body, melt pressure high, high melt strength, late plasticizing capability. The lower mechanical properties and weather resistance of PVC material, but the latter almost does not affect the mechanical properties of PVC material, and the weather has changed Be good.

Some processing type ACR plasticizing effect is good, for a formulation for the PVC will greatly improve the current and torque of extruder, improve the plasticization of PVC, but for another kind of PVC formulations may make color darker colour deviation of PVC products. Sometimes a processing type ACR in rapid extruder is appropriate, but is not necessarily appropriate in slow extruder, and vice versa. Because of this, want to make a processing type ACR to satisfy different formula, different products, different processing equipment requirement is almost impossible. Similarly, the traditional processing aid ACR, should not only meet the plasticizing quickly, and to meet the needs of high melt strength, melt pressure processing requirements, it would be impossible. To meet the personalized requirements of customers, we have developed a series of new with different promote the plasticizing properties and different processing aid agent other characteristics, to adapt to the user's requirements, the performance of some of the products has been completely can replace imported products, we are on the performance of these processing aid and use method has carried on the detailed study, as long as the customer put forward his own specific to beg, the new material research center can recommend the suitable products type, dosage and method of use.
