New Structural Thermoplastic Compounds That Outperform Mechanical Strength of LFT

Now a days customer demand for a short fiber thermoplastic material that would outperform the mechanical strength of long fiber thermoplastic (LFT) materials. Responding the demand Piper Plastics has developed the KyronMAX™ series of structural thermoplastic compounds - the next generation in injection moldable metal replacement technology.

Overcoming Limitations of LFT Compounds

David Wilkinson, Polymer Technology Manager at Piper Plastics, explained:
“Our customers wanted the strongest moldable polymers available without all the process and design limitations associated with LFT polymers. KyronMAX materials consistently outperform LFT polymers, especially when measuring the performance of the molded part, which is the true test. They overcome all the limitations associated with LFT compounds while yielding stronger molded parts that are also lighter in weight.”

Uniqueness of Technology

What makes KyronMAX technology unique is that it is based on short fiber technology:
  • 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. 
  • An exciting feature of short fiber technology is that very complex parts can be molded with wall thicknesses down to 0.015” (0.038 cm). 

KyronMAX Technology Performance

Competitive structural compounds use high fiber loadings and long fiber lengths to achieve the desired mechanical performance. But the performance of these materials often does not translate into the molded parts, due to weld line strength loss and fiber length reduction during processing. In contrast, KyronMAX technology outperforms all other thermoplastic compounds using short fiber technology and much lower filler loadings.

David Wilkinson said:
“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 Replaces LFT

Formulations Based on KyronMAX Technology

Exhibiting tensile strengths above 51,000 psi (352 MPa) and flexural modulus above 6,500,000 psi (44,816 MPa), the KyronMAX technology platform is currently formulated in various thermoplastics including PA, PPA, PPSA, PEI, PEEK, with more in current development.
