Additives (K 2001 Preview)
This year’s show will present such a large number of new polymer additives that only a few categories can be covered this month: antioxidants, halogen and non-halogen flame retardants, PVC heat stabilizers, and impact modifiers. Next month, we’ll report on new uv stabilizers, colorants, additive concentrates, lubricants, and more.

Foaming Expands Possibilities for Wood-Fiber Composites
Over a dozen processors already foam wood-fiber composites and an equal number are experimenting with it. Foaming with wood cuts resin cost and weight in half and brings design advantages. But it also requires particular know-how in materials formulation and extrusion hardware.

New Compounding Options Strengthen Pull of Molded Magnets
Thermoplastic polymer-bonded magnets are exerting a stronger pull on designers of motors, valves, sensors, and other electronic devices used in cars, telecommunications devices, and large appliances. The attraction is strongest in applications demanding greater design freedom than is offered by conventional magnets sintered from 100% metal powder.
