There are many ways to identify plastic materials, such as material density, hardness, brittleness and other materials can not simply be used to evaluate whether it is good or bad, because different materials have different properties and functions. Its material properties are as follows:
1. Good comprehensive performance, high impact strength, chemical stability and good electrical properties.
2. It has good weldability with 372 plexiglass, and can be made into two-color plastic parts, and the surface can be chrome-plated and painted.
3. There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other grades.
4. The fluidity is a little worse than HIPS, better than PMMA, PC, etc., and the flexibility is good. basic properties.
Uses: suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunication parts.
How to distinguish: ABS engineering plastics are generally opaque, light ivory in appearance, non-toxic, tasteless, and have the characteristics of toughness, hardness and rigidity. They burn slowly, the flame is yellow, and there is black smoke. After burning, the plastic softens and burns. , emits a special cinnamon smell, but no melt dripping phenomenon.
