HUDSON, Ohio—One of Alpha Technologies' latest developments extends the Premier-brand Rubber Process Analyzer's compound testing to include sub-ambient temperatures, arming tire manufacturers with options for more efficient and accurate testing.
The Hudson-based firm, which specializes in rubber rheology testing, has dubbed its new advancement the Premier RPA with Sub-Zero Technology, solidifying the Alpha instrument's reputation as the "most versatile in the market," according to a company news release.
Alpha said the new technology gives tire makers a more accurate way to perform compound testing throughout a wide range of conditions. Traditionally, tire firms would need multiple instruments to run both RPA and Dynamic Mechanical Analysis testings.
Now Alpha customers can use the Premier RPA with Sub-Zero Technology to test for cure characteristics and tire tread performance predictors for rolling resistance, winter traction, handling/cornering and wet traction. It added that the new machine offers sub-ambient testing capabilities without the use of liquid nitrogen down to -25°C, and significantly cuts in-process testing time to as little as 25 minutes.
For customers, that means greater testing capabilities along with the potential to reduce capital spending and operational costs, Alpha said. The sub-ambient operating range also can be useful in automotive anti-vibration systems, sealing technologies and other rubber applications.
