Product Profile:
Industry: Confidential
Application: Rotating pendulum noise isolating bumper
Material: Thermoplastic Urethane (TPU)
Customer Issue:
The fabricator was having the following problems with the processing of
a TPU material:
Non-fills / short shots
Pin-push deformation
Parts sticking in the mold
ExCista Solution: Silaplast™ ES7712
This pelletized siloxane additive acts as an internal lubricant during
processing, improving flow and slip properties for better mold fill and
throughput. Metered into the polymer mix automatically at just 1% by
weight, the additive also reduces the coefficient of friction (COF) on the
surface of the molded part, resulting in easier mold release
Results:
Non-fills / short shots -- eliminated
Pin-push deformation – not visible
Parts eject without sticking
30% reduction in total cycle time
