ColorMatrix Amosorb Oxyloop to enhance recyclability.

After 60 years at the firm started by his father, John Winzeler is retiring and has sold his gear molding business to a ...

According to AIMPLAS, the new accelerated biodegradation test subjects materials to simulated industrial composting conditions in order to measure the conversion of polymeric carbon into CO₂. Thanks ...

Xaloy has launched TriMetalX, an extruder barrel that the company says offers more durability and performance for processing highly corrosive resins. TriMetalX barrels are built via a proprietary ...

The intensification ratio is equal to the ratio of the effective areas of the hydraulic ram to that of the screw check valve. Since those values often are not readily available, the intensification ...

Melt Flow Rate Testing–Part 1 Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind ...

Perhaps the greatest difficulty involving the use of color concentrates is specifying them appropriately for the material to which they are being added.

Density & Molecular Weight in Polyethylene This so-called 'commodity' material is actually quite complex, making selecting the right type a challenge.

Aimed at complex profiles such as PVC lineals, retrofittable system adds turbulent cooling to calibrator to boost output by 25-50%.

Understanding Melting in Single-Screw Extruders You can better visualize the melting process by “flipping” the observation point so the barrel appears to be turning clockwise around a stationary screw ...

Rethinking Regrind Regrind and recycled material are often requisite in projects these days, but for many molders, the “R” word triggers painful memories.
