Engineering Plastic Alloy Compatibilizers

To meet market demands, the polymer processing industry needs to continuously develop new materials. In this process, a common method is to rationally combine existing materials, hoping to obtain polymer blends that combine the advantages of various basic materials, commonly known as polymer alloys. Blending can improve the physical and mechanical properties, processing performance, reduce costs, and expand the range of use of polymer materials.

However, in practical operations, the compatibility between polymers is relatively complex, with some being fully compatible or partially compatible, while others are completely incompatible or partially incompatible. Blends that are fully compatible are due to their identical polarity and similar structure, and the performance of such blends is not significantly improved. Since most polymer systems are immiscible, they cannot be mixed together without phase separation/delamination.

If two materials are incompatible, we can add a third component that is compatible with both the first and second materials. We call this third component a compatibilizer, which is the key to compatibilization technology.

The main function of a compatibilizer is to:

1. Reduce the surface tension between the two polymers, promote the dispersion of the phases, and prevent the coalescence of the dispersed phases;

2. Increase the thickness of the interfacial layer, enhance the interphase bonding strength, improve thermal stability, and increase stress transfer efficiency;

Reduce the particle size of the dispersed phase, form a stable phase structure, and provide uniform and stable properties for the material.

Therefore, after adding a compatibilizer, the deterioration in notch impact performance caused by the originally incompatible system can be significantly improved.

Jiuju Company provides a series of reactive compatibilizer solutions for polymer alloys, enabling the composites industry to create blends of different types of polymers. The product portfolio includes maleic anhydride (MAH) type compatibilizers, acrylic acid type compatibilizers, and glycidyl methacrylate (GMA) graft compatibilizers. When manufacturing polymer blends with different components, the blend always contains a continuous phase, which is the main component of the polymer blend. This continuous phase is crucial for determining the correct compatibilizer. Jiuju can provide advice on selecting the right compatibilizer for you.

In the field of engineering plastics, the addition of reactive compatibilizers allows for the combination of different polymers. The triangle in engineering plastics illustrates the opportunity for miscible polymers to blend with reactive polymers under the influence of compatibilizers.

For different application scenarios, this series of products offers a variety of grades. If you need precise model selection, please contact our sales engineer for the best solution recommendation.
