Selecting Thermoplastic Materials for Performance, Cost, and Feel

At the Cyclitech 2016 conference, Eric Larson gave a presentation on the issues involved in selecting thermoplastic materials for use in the bicycle industry.

Performance Plastics are not the cheap, flimsy plastic that your grandmother used to complain about – they are high performance materials that can often wreak havoc on the performance of traditional materials such as tin, iron, copper, and steel.

Now this is news that will make you smile!

toughness - whatever property that is lacking in that part that just broke

A Gardener Test Gone Wrong
In the world of engineering, the term toughness is used to describe the ability of a material to withstand sudden impact without failure. It is a simple concept, but the toughness of a material is often difficult to accurately measure. What exactly is a “sudden” impact? What is, and is not, failure?

The simple answer: Maybe

Using re-grind in the injection molding process essentially means you are using a resin blend. The end result can be a mangy mutt, an elegant Bordeaux, or something in between.

The Four Horsemen of the Plastic Apocalypse

The Four Horsemen of the Plastic Apocalypse
Extreme environmental conditions - such as temperature, chemicals, radiation, even time – can wreak havoc on the performance of thermoplastic materials. I like to call the conditions the Four Horsemen of the Plastic Apocalypse.

Selecting Plastics for High Heat Performance

Unlike many other materials, thermoplastic materials have a unique relationship with heat.

Musings on Plastics, Poetry and Works of Art

Eric Muir 700
A few weeks ago, I took a journey up the California coast to Big Sur, one of my favorite places in the world. I attended a 5-day hiking workshop at Esalen, hiking into the wilderness during the day, settling back into the soul in the evening. It was a week of magic and mystery, mixed in with some poetry from John Muir. I even wrote a Muir-ism of my own.

A Method for Technical Evaluation

Feel is often an overlooked aspect of material selection, but it offers significant advantages.
