Electronic applications requiring more than Heat Dissipation: How can you fulfill their need?

By Mark DeMeuse

Thermal management has always been a major concern in the design of high frequency, high power electronic devices. For example, historically, in many power amplifier designs, the vast majority of the power that needs to be dissipated is from the high power field effect transistors, or FET's, themselves. In these cases, the high power dissipation ...

Why are TPUs getting back into the 'rat-race' of the Sports & Leisure industry?

By Thibaud Deleger

From the elastomeric materials, side significant changes occurred in these past years, with many more options offered to product designers and engineers. Vulcanized rubbers were the first to be developed, and therefore have a long history in multiple uses. Flexible PVC entered the game, and thanks to their cost competitive pricing and almost infini...

Development of Low Gloss Polyacetal

Nowadays low gloss Polyacetal (POM) materials are required for automotive interior parts. In this study, new low gloss POM was developed. Original organic particles having effective interaction with POM, was developed as the matting agent. Consequently, excellent low gloss appearance with a good balance of mechanical properties is obtained. In addi...

Effects of Painting on the Mechanical Properties of Injection-molded Plastics

Paint can have significant effects on the mechanical properties of plastic substrates. The selection of a paint system that is not properly matched to a given plastic substrate can lead to premature failure. While anecdotal accounts are plentiful, quantitative data regarding effects of coating on plastics is scarce. This paper describes the effect ...

Effect of Design on EPS Cup Strength

Billions of disposable coffee cups are used annually around the world. Most of the cups are molded using expandable polystyrene (EPS). EPS is a very complex material with many structural variables that affect the strength of molded parts. Lab testing and computer FEA analyses of the most common cup designs reveal that cups having a flared rim desig...

Can PVC survive after concerns on phthalates?

The move towards phthalate-free polymers keeps going on in the Medical Industry, as well as in many other sectors. Started more than a decade ago, it is now a matter of fact "phthalate-free" has become a marketing claim itself and not a technical or customer-specific requirement anymore. Denmark was one of the first countries in the world (not to s...

Structural Bonding Alternatives for Plastics

Plastics have become an integral part of everyday life. It would be difficult to identify a manufacturing process which does not use plastics in one from or another. Even products which appear to be composed exclusively of metals are usually coated, sealed, or adhesively joined using polymeric materials which improve the performance, appearance, an...

Cellulose-based Nanocomposites for Structural Applications

Biocomposites incorporating cellulose fibres, a renewable resource, have high modulus and strength and flexibility suitable for structural applications. Solution casting, ultrasonication, and compression moulding methods were used to prepare the specimens. Results show that plasticisers improved the flexibility of the composite and adding fillers f...
