I just wonder what's so special about ABS plastic. I read about it everywhere, but I can't find a thing about what's so special with ABS plastic, that makes it better than "regular" plastic. Anybody here know?

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

As I recall, it's easy to injection mould, relatively cheap, and extremely impact-resistant, as well as easy to colour and add metallic finishes to.

Anything else, I'd have to track down my old CDT notes for.

as pipe goes, it costs a little more than PVC

but its supposed to be better because its light, very heat and impact resistant, and if it does break it wont shatter and spray shrapnel, it just cracks in a very neat line. its used in thing that are under pressure too just for safety reasons.

I know from lacrosse they make helmets and shoulder pads out of it too.

Ok, thanks.

i know its not safe to use pvc for smoking because its toxic. abs?

Polychloroethane, or PVC, as the name implies, has the Chlorine atom as part of the molecule. If you burn PVC, Cl₂ gas will be released. This is what's toxic.

I'll just do it from wiki:

Acrylonitrile is a synthetic monomer produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from butane; and styrene monomers, derived from coal, are commercially obtained from benzene and ethylene from coal. The advantage of ABS is that this material combines the strength and rigidity of the acrylonitrile and styrene polymers with the toughness of the polybutadiene rubber. The most amazing mechanical properties of ABS are resistance and toughness. A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. The impact resistance can be amplified by increasing the proportions of polybutadiene in relation to styrene and acrylonitrile although this causes changes in other properties. Impact resistance does not fall off rapidly at lower temperatures.

Duh.

Some airsoft guns are made out of ABS plastic.
