Piper Plastics, a leading provider of high performance
polymer materials and precision machined plastic components
and assemblies, developed the KyronMAX™ series
of structural thermoplastic compounds, the next generation
in injection moldable metal replacement technology.
“Our customers wanted the strongest moldable polymers
available without all the process and design limitations
associated with LFT polymers,” explained David
Wilkinson, Polymer Technology Manager at Piper Plastics.
“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.”
What makes KyronMAX technology unique is that it is
based on short fiber technology, so 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. 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).
Competitive structural compounds use high fiber loadings
and long fiber lengths to achieve the desired mechanical
performance, but 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, KyronMAX technology outperforms
all other thermoplastic compounds using short fiber technology
and much lower filler loadings.
“We are consistently replacing LFT polymers with
KyronMAX polymers that are 20% lighter and 20-50%
stronger,” said Wilkinson. 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
