Material selection

Welcome to QUANDA

Wholeheartedly, to reach you

Our reputation has been built on the prominent ability of assisting customers to pinpoint the most appropriate engineering plastic. According to client-side requirements, we can help our customers choose an appropriate type of material to fit their individual demands

As a prestigious manufacturer of engineering plastics and profiles, we believe that the most initial factor to preferred products lies in the accurate material selection at minimal cost. Normally, we put following aspects into consideration.

plastic material selection

1. Application

The first thing is to analyze applications of products, which include desirable mechanical performance, specific requirements and working environments.

2. Design

We switch natural demands into material properties, so as to make the product more specific yet versatile. Moreover, we apply simulation tests and experience to proffer more optimal design.

3. Material selection

After confirmation of technical data, the next thing is to choose the best material compatible with these properties. Firstly, we collect property information. It is impossible and unnecessary to read through all the available information, so we filter candidate materials on the basis of our experience. Then, we narrow the scale by the most important application needs and environment limits.

The following data sheet is for your reference when choosing engineering plastics. Values in the sheet indicate levels of each property. The smaller number implies better property. However, before selection, you need to define some most desirable properties.

For example, if the working environment is strong acid, then PTFE is the choice. If PTFE offers insufficient toughness, then you can choose PVDF instead. When toughness is the predominant requirement, both POM and Nylon 6A are well-suited. But, if dimension is also as important as toughness, then the final selection is POM.
