Is PTFE a Thermoset or a Thermoplastic?

Many assume that polytetrafluoroethylene is a thermoset because it seems unaffected by heat.

Material Selection Process for See-Through Kettles Not Transparent

We like our see-through kettles and take them for granted but they have a punishing life cycle.  Over 10 years the kettle could undergo a total of 10,000 cycles. It is filled with cold water, […]

Why does PPO have to be ‘Modified’?

Polymer scientists worked out that the molecular stiffness of the backbone of a polymer chain was the key to increasing the glass transition temperature (Tg) and hence rigidity at elevated temperatures.

Let it Snow, Let it Snow…

Around this time of year, we see a lot of artificial snow.  A favourite trick of the special effects experts is to exploit an unusual acrylic polymer.

The Hidden Attributes of Polycarbonate

When polycarbonate (PC) first appeared in the market over 50 years ago, the immediate appeal was its amazing impact resistance compared to other transparent rigid thermoplastics at that time.

Can Environmental Stress Cracking Be Avoided?

Environmental stress cracking (ESC) is the development of cracks and eventual catastrophic failure due to a combination of mechanical stress (from external loading or from moulding strain) and exposure to an ‘aggressive’ chemical (a ‘near […]

What is Environmental Stress Cracking?

Environmental stress cracking (ESC) is not the result of the continual battle that the plastics industry has in convincing environmentalists and politicians that plastics can be the solution to environmental problems and not the cause.

Just Why Would You Choose ABS?

ABS is one of the original engineering thermoplastics. A classic all-rounder with a good blend of performance and aesthetic properties.

What are Engineering Thermoplastics?

Today the term is conveniently applied to certain families of thermoplastics which have a higher performance than the group of thermoplastics labelled ‘Commodity Thermoplastics’.
