~ Penjelasan Material Plastic di Model kit, khususnya GunPlaMo
ABS plastic is what your Playstation 1 shell (or other console system plastic shell) is made out of. It’s also what most Gundams are made out of. ABS is much harder, and is typically smooth. You can add texture toit, but it’s typically not a very fine texture. It’s impossible for paint to stick, so it almost always has to be primed first. Also, because of it’s hard nature, it’s impossible to get details that are more than 90 degrees angle, because otherwise the piece will be caught in the mold. That’s why all injection kits edges are always perpendicular. It can be round on the top all the way down to the edge, but it cannot go beyond that 90 degree mark.
ABS is made from a combination of monomers made from propylene, ammonia, butane, and coal. The advantage is that it combines the strength and rigid properties, as well as the rubbery toughness (ABS can bend without snapping). ABS is by far the strongest plastic used for making figurines. So while PVC is soft and rubbery in resilience, ABS is tough and rigid.
Polystyrene (PS) - Polystyrene is an amorphous, glassy polymer that is generally rigid and relatively inexpensive. Unfilled polystyrene has a sparkle appearance and is often referred to as crystal PS or general purpose polystyrene (GPPS). High impact polystyrene grades (HIPS) are produced by adding rubber or butadiene copolymer which increases the toughness and impact strength of the polymer. Polystyrenes possess good flow properties at temperatures safely below degradation ranges, and can easily be extruded, injection molded, or compression molded. Considerable quantities of polystyrene are produced in the form of heat-expandable beads containing a suitable blowing agent which ultimately results in familiar foamed polystyrene articles.
Transparency, excellent toughness, thermal stability and a very good dimensional stability make Polycarbonate (PC) one of the most widely used engineering thermoplastics. Compact discs, riot shields, vandal proof glazing, baby feeding bottles, electrical components, safety helmets and headlamp lenses are all typical applications for PC.
