Siloxanes Are chemical compounds with a backbone of alternating silicon (Si) and oxygen (O) atoms, each silicon atom bearing one or several organic groups, as be seen in the image 1, are very flexible due to large bond angles and bond lengths compared to those found in more basic polymers. Siloxanes are building blocks for silicone …
Thermoplastics Processing Methods
Thermoplastics are materials which soften when heated and can then be formed whilst soft. After cooling they becoming rigid take up the applied form. The softening and forming processes are reversible. Thermoplastics are probably the most widely used type of polymer. The group includes most of the “commodity” plastics such as polyethylene, PVC, polypropylene, nylons (polyamides) and polystyrene. Not all thermoplastics can be processed by all the methods. This table is a guide to what thermoplastics can be processed by each method.
Thermosetting Processing Methods
Thermosetting materials are materials that are formed whilst warm or hot but once formed they set in the formed shape. Cooling and reheating do not make thermosetting materials go soft again. The forming process is not reversible. Thermosetting materials were the first type of polymer to be produced e.g. bakelite, but are still widely used for many applications. Typical thermosetting materials are phenol formaldehyde resins, urea formaldehyde resins, epoxy resins and most rubbers.

The demand for effective thermal management solutions in electronic equipment is on the rise as a result of rapid technological progress. These solutions aim to ensure that system devices operate at an acceptable temperature level to reduce the risk of damage and ensure the longevity of components. The traditional method of dealing …
Batteries challenge Battery manufacturers are currently challenged to produce large volumes of smaller, lighter, and cheaper lithium batteries. These higher energy density packs deliver more power, over a longer period of time, but to do so they need to avoid overheating and heat spikes, i.e. better thermal control. Thermal control In order …
