ABS plastic

ABS is a "polymerized alloy" of the tree materials: Acrylonitrile, Butadiene andStyrene. The material is located under the group styrene plastic. Styrene plastics are in volume one of the most used plastics.

The mechanical properties for ABS are excellent for impact resistance and rigidity. The material is tough and stiff, and the properties are kept over a wide temperature range. Generally ABS have useful characteristics within a temperature range from -40 to 100 °C. Even though ABS plastics are used largely for mechanical purposes, they also have good electrical properties that are fairly constant over a wide range of frequencies.

The weather resistance for ABS is drastically improved by additives (pigments) to stabilize it against UV /ultra violet/ rays. This is one of the reason why in most outdoor application, an grey coloured plastic is used. It is resistant against sunshine and does not change colour /fade/ over years. The chemical resistance for ABS is good. ABS resists water, non organic salts, acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils.

ABS is widely used for auto body parts, consumer products, toys etc. We use various types of ABS for extrusion and injection moulding.

Aluminium
Aluminium is the most widely used non-ferrous metal. Aluminium alloys show high strength-to-weight ratio. Aluminium readily forms alloys with many elements such as copper, zinc, magnesium, manganese and silicon. Almost all bulk metal materials that are referred to loosely as "aluminium", are actually alloys. For example, the common aluminium foils are alloys of 92% to 99% aluminium.

In antenna construction, aluminium is used as mechanical component using its excellent strength-to-weight ratio, as well as material for construction of antenna feeders. We also use micro layers of aluminium deposited onto a flat surface by physical vapour deposition /PVD/ to form aluminium coatings.
