Close-Up on Technology

Now It's Here: An Objective Test of Masterbatch Dispersion
There's a new grading system for color concentrates and additive masterbatches.

Novel Processing Aids Ease Flow Of a Wide Range of Plastics
A new family of processing-aid masterbatches is said to enhance the processability of a wider range of plastics than is possible with other additives.

TPUs Get Softer, Slicker, Lighter
BASF Corp., Wyandotte, Mich., has launched a new range of thermoplastic poly urethanes that push the performance envelope in several directions.

Features

Additives for Polyolefins: Newest Advances Add Ruggedness, Good Looks & Easier Processing
At a recent conference, suppliers revealed novel coupling agents for wood composites and nanocomposites, unusual nucleator masterbatches for OPP and thermoformed containers, and enhanced heat and light stabilizers, flame retardants, and processing aids.

What's Next: In-Mold Everything
The days are long past when an injection mold was a passive receptacle for melted plastic.

'Corrugator Vacuum Forming'
Molding separate hollow parts on a pipe corrugator is a home-grown technique used by a small number of processors. They discovered it offers higher outputs and numerous other advantages over blow molding for making tube-shaped, precision medical, automotive, and appliance parts. But the process has not yet realized what could be its greatest potential in closed-end parts like bottles.

Strategies

On the Cutting Edge of Multi-Shot Molding
Easley Custom Plastics (ECP) Inc. doesn't want to be just your average small to medium-sized custom molder.

Troubleshooter

Eliminate Surface Defects on Molded Parts
Visible defects on the surface of a molded part appear as dull, glossy, or hazy areas, or as a rippled surface, called orange peel.
