There are many ways to distinguish plastic materials, such as material density, hardness, brittleness, etc. Materials cannot be simply evaluated as good or bad, because different materials have different properties and different functions. Chemical name: Acrylonitrile-butadiene-styrene copolymer, its material characteristics are as follows:

 

Good overall performance, high impact strength, chemical stability, and good electrical properties.

 

It has good weldability with 372 plexiglass and is made into two-color plastic parts, and the surface can be chrome-plated and painted.

 

There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other levels.

 

The fluidity is slightly worse than HIPS, better than PMMA, PC, etc., and flexibility is good. Basic attributes.

 

 

Uses: Suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunications parts.

 

How to distinguish: ABS engineering plastics are generally opaque, with a light ivory color, non-toxic, and tasteless, and are tough, hard and rigid It burns slowly, and the flame is yellow with black smoke. After burning, the plastic softens and scorches, giving off a special cinnamon smell, but no melting and dripping.
