Nowadays, high temperature applications are commonly used in our daily life, which involve in many fields like medical, automotive, home appliances, electronic, industrial and so on. These kind of applications require plastics to have good creep resistance, chemical resistance, and friction and wear performance in high temperature environment.

SuNPe has rich experience in producing projects with heat resistant plastic to support customers from various industries. We have a range of heat resistant materials for different techniques, which supports not only prototyping and pilot production, but for short-run manufacturing and mass production as well.
 

The heat resistant materials we have.


SuNPe offers block materials like PTFE(Teflon), PPS, PEEK, PEI, PBT, PET, PA6+30%GF, etc for CNC machining. PU material(PX527 and PX223HT) for vacuum casting. PA46, PPS, PEEK, LCP, PTFE, PVDF for injection molding.

Now you know what kind of material we can provide to you, then how to choose the right material for your projects? Here we have some tips for you.
 

Knowing which temperature will the plastic work at.


Heat resistant plastics can maintain their mechanical properties without negative effect while working in high temperature. The ideal working temperature is with large rage from 120 degree to 350 degree. You need to know the temperature that the products will work at, and you can choose the right plastic to withstand the high temperature.
 

Knowing what kind of environment will the plastic meet.


In addition to maximum operating temperature, there are many other factors we should take into consideration when choosing the materials, such as chemical resistance, tensile strength, and wear performance. You should know where the plastic will be used for. For example, for automotive industry, medical devices, food industry or others? For different usage, suitable materials will be different.
 

Defining the stage that your project is in.


For different stage of the project, you might consider to produce in different technique, it’s a reasonable step for controlling cost and time, when promoting the project. For different techniques, the form of heat resistant plastics can be various, like block type, liquid, powder, etc.

Having an overview of the plastic you need, you will have a right selection of the material. Welcome to contact us to proceed your project.
