Toughening Agent for PBT and Its Alloy

Product Introduction

Fine-Blend ® SOG-02 is a POE-g-GMA product, due to the reactivity of GMA higher than MAH, it can effectively improve the notch sensitivity of polyester material. The toughening efficiency of SOG-02 is same as E-MA/BA-GMA terpolymer, however, because of its unique molecular structure design, when used in polyester material, the former was better on processing fluidity, this can reduce processing defect of product and enhance productivity.

Mechanism and Advantage

GMA was grafted to the main chain of ethylene elastomer, so SOG-02 has high reactivity with the terminal carboxyl group of polyesters material; therefore, it can achieve the goal of increasing toughening and compatibility. Product structure diagram is as follows:
