A flow rate test is used to work out the melt flow rate (MFR) of a thermoplastic material. According to ASTM 1238, “Method A” test involves the collection of extrudate from the die over a set period ...

Panametrics has developed several ultrasonic, clamp-on flow meters for measuring fluid flow. These clamp-on meters can be ...

This is the second of eight articles from our Nozzle Knowledge Series. Prefer to watch a video, click here. Flow rate, the volume of water passing through a nozzle, per unit of time, is clearly an ...

Method A/B is a test that can be performed in a melt flow rate tester so as to calculate the value of the polymer’s melt density at a certain temperature. Both a “method A” test and a “method B” test ...
