Polymer properties database


In most cases, polymers - generally referred to as plastics or elastomers - are amorphous molecular chains of carbon atoms with branches of other atoms such as hydrogen, nitrogen and oxygen.

In thermoplastics, adjacent molecules are free to move relative to each other, which results in molten matter when exposed to excessive heat.

Whereas adjacent molecules in thermosetting plastics are interlinked by ionic bonds, which means that excess heating will cause the material to burn rather than melt.

Polymers are weaker and less predictable than crystalline materials such as metals, limiting them to low strength and low temperature applications.

On the other hand, however, their pliability may be advantageous in that they can deform readily with little or no reduction in strength, making them suitable for flow and low-pressure piping, and packaging. Moreover, two of them; polyethylene terephthalate and polycarbonate, are mechanically almost indestructible, the latter of which gives us a transparent material stronger than glass.

Polymers is a comprehensive and simple to use database of the primary properties of approximately 100 polymers including; thermoplastics, thermosetting plastics, elastomers and thermoplastic elastomers, with and without reinforcement.

It is the only polymer database of which we are aware that provides a documented value for every property of every polymer; all of which can be sorted according to value magnitude.

We are bound, however, to warn that - apart from specific heat capacity values in this database - all documented values for all polymers irrespective of source, must be considered approximate.

Sorting a particular property, will also sort all 'Names' and 'Abbreviations (symbols)' into the same order.

All the properties for the polymers selected via ‘Names’ or [polymer] 'Groups’ will appear in the main window.
