FB521A

Product Description：

Fine-Blend® FB521A is a maleic anhydride functionalized semi-crystalline ethylene copolymer with excellent flexibility and elasticity. Its fully saturated backbone results in outstanding thermal and oxidative stability leading to enhanced weatherability. Moreover, its elastomeric nature provides high impact resistance at room and low temperature when compounding with engineering polymers such as polyamide.

This grade is designed as:

Nylon impact modifier - Enhance the room and low temperature flexibility of nylon (PA6 and PA66) with higher flowability and processability;

Adhesion promoter - Using as concentrate grade to promote adhesion of unmodified polyethylene and polypropylene to polar materials such as Metal, Nylon, EVOH, et al;

Compatibilizer - Acting as a solid surfactant to increase interphase adhesion and achieve compatibility between most commonly used polar polymers (such as Nylon) and polyolefins;

Coupling agent - Actin
