There are many methods for distinguishing plastic materials. For example, materials such as density, hardness, and brittleness cannot be evaluated simply because they have different properties and different functions. Chemical name: acrylonitrile-butadiene-styrene copolymer, its material properties are as follows:
Good comprehensive performance, high impact strength, chemical stability and good electrical performance.
And 372 plexiglass has good weldability, made into two-color plastic parts, and can be chrome-plated and painted.
Has high impact, high heat, flame retardant, enhanced, transparent and other levels.
The fluidity is a little worse than HIPS, better than PMMA, PC, etc., and good flexibility. Basic properties.
Uses: Suitable for making general mechanical parts, wear-resistant parts, transmission parts and telecommunications parts. How to distinguish: ABS engineering plastics are generally opaque, the appearance is light ivory, non-toxic, tasteless, both tough, hard, just The characteristics are slow burning, the flame is yellow, and there is black smoke. After burning, the plastic softens and burns, giving off a special cinnamon smell, but no melting dripping.
