| Title: HIGH IMPACT-STRENGTH (NYLON) POLYAMIDES Inventor(s): N.
Nakajima
Disclosure 210 U.S. Patent 5,376,712
The objectives of this invention were to develop nylons with significantly higher
impact strength compared to general purpose nylons, and without sacrificing the stiffness
such that the load-bearing capability is limited (referenced table). In addition, another
objective was to ensure that the process to create these enhanced materials was both
simple and economical relative to other high impact-strength modified nylon technologies.
Developmental costs is minimal, process is simple, and scale-up to commercial volume is
not a problem as existing production line and equipment can be used. This technology is
considered "drop-in" technology with a very short developmental time-line to
bring this material to the commercial market.
This technology is ideally suitable for mechanical applications where high
impact-strength and high flexural modulas are required. Suitable products include
automotive body components such as headlight housings; housings for cameras, electronic
equipment and instruments; sports equipment such as sports racquets; tool housings, and
the like.
