There are many methods for distinguishing plastic materials, such as material density, hardness, and brittleness. Because different materials have different properties and different functions. Chemical name: acrylonitrile-butadiene-styrene copolymer, its material properties are as follows:
1. Good comprehensive performance, high impact strength, chemical stability and good electrical performance.
2.and 372 plexiglass has good weldability, made into two-color plastic parts, and can be chrome-plated and painted.
3. has high impact, high heat, flame retardant, enhanced, transparent and other levels.
4. 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, there is black smoke, the plastic softens and burns after burning, and a special cinnamon smell is emitted, but there is no melt dripping.
