Some problems in the application of PC / ABS polymer alloys are discussed

Poor stability of material processing will lead to appearance defects such as silver wire and gas mark on the surface of products; The poor combination of alloy phase and state will lead to assembly cracking, missing plating, peeling, welding and other problems; Of course, other problems, such as paint cracking, color difference, gloss and so on, can also lead to material complaints.

Let's first learn about the comparison between ordinary PC / ABS and high-performance PC / ABS

Ordinary PC / ABS

1. Poor processing stability and easy degradation

It is easy to degrade under the conditions of strong shear, high heat and moisture; Silver wire, gas mark, yellowing and other defects are easy to appear, and the melt finger rises greatly after injection;

2. Phase instability

It is easy to cause phase instability and brittle fracture when injection molding long, thick and complex parts; The impact strength fluctuates greatly and the data dispersion is large;

High performance PC / ABS

1. Good processing stability

Under the condition of high heat, moisture and strong shear, it can keep its properties; The color, appearance and impact property are stable before and after processing, and the rising range of melt finger is small;

2. Phase stability

Weld lines, stiffeners, corners, thin walls and other complex structures,

The parts keep high toughness; The impact strength fluctuation is small and the data dispersion is small.
