KyronMAX™ Structural Thermoplastic Materials
vs.
Long Fiber Thermoplastic Compounds


The KyronMAX™ series of structural thermoplastic materials outperforms the mechanical strength of long fiber thermoplastic (LFT) materials, especially when measuring the performance of a molded part. The material overcomes all the limitations associated with LFT compounds while yielding stronger molded parts that are also lighter in weight.

Want to see the true functional performance between KyronMAX materials and LFT compounds?

Watch the video below to see what happens when a top archery company tries to qualify a polymer composite wheel. Their most aggressive performance test is to ‘dry fire’ the bow without the arrow. In this test, all the kinetic energy is transferred into the idler wheels, which generates dramatic stress and impact.

In contrast, the KyronMAX material technology outperforms all other thermoplastic compounds using short fiber technology and a lower percentage of filler. The lower filler content results in a tough, structural plastic that can be utilized in extremely aggressive applications, yet is still processing friendly and does not require specialized molding equipment.

KyronMAX Materials Outperforms LFT Without the Processing Issues Associated with Long Fiber

What makes the KyronMAX material technology unique is that it is based on short fiber technology, which means the polymer behaves more like the isotropic nature of metal and eliminates the processing and fiber breakage concerns associated with LFT compounds. The technology enables very complex parts to be molded with unrivaled mechanical performance and consistency.

KyronMAX Materials vs. Other Structural Compounds

Competitive structural compounds use high fiber loadings and long fiber lengths to achieve the desired mechanical performance. Unfortunately the performance of these materials often do not translate into the molded parts, due to weld line strength loss and fiber length reduction during processing.

In contrast, the KyronMAX material technology outperforms all other thermoplastic compounds using short fiber technology and much lower filler loadings. The lower filler content results in a tough, structural plastic that can be utilized in extremely aggressive applications, yet is still processing friendly and does not require specialized molding equipment.

Both parts look the same from the outside, but look inside the part...

The following mold flow fiber plot shows the significant difference in strength between long fiber thermoplastics (LFT) and KyronMAX polymer.
