Disadvantages of PE and PTFE

Although PE and PTFE have many advantages, they also come with some drawbacks that you should consider before making your decision. PE is not as resistant to chemical attacks as PTFE, so it is more likely to be damaged by solvents and other chemicals. It also has a lower melting point than PTFE, which means that it may start to deform or soften when exposed to higher temperatures. Moreover, PE can only be used for low temperature applications due to its fragility and low melting point. Finally, it is difficult to cut through due to its brittle nature, thus requiring special tools for fabrication.

On the other hand, PTFE is very difficult and expensive to fabricate, making the cost of production high. It also isn't biodegradable, so any waste must be disposed of carefully in an eco-friendly way or recycled properly. Additionally, because of its non-stick properties, it can cause contamination if not handled with care during manufacturing processes. Finally, some versions of PTFE are sensitive to UV radiation, which could potentially weaken the material over time leading to reduced performance levels.

For both materials, there are certain disadvantages that must be considered before picking either one for specific application needs:

• PE is not as resistant to chemical attacks as PTFE
• It has a lower melting point than PTFE
• PTFE has a difficult and expensive fabrication process
• It is not biodegradable, so waste must be disposed of carefully
• Some versions of PTFE are sensitive to UV radiation.

Cost Comparison

Now that we've discussed the disadvantages of polyethylene (PE) and PTFE (Teflon), let's talk about cost.

When it comes to cost, PE tends to be more budget-friendly than PTFE. This is largely due to the fact that PE is a lot easier to manufacture than PTFE, so its production costs are lower. Additionally, since PE has been around for longer than PTFE, there is a larger variety of manufacturers which also helps bring down prices.

On the other hand, PTFE is more expensive due to its complex manufacturing process and limited number of suppliers. However, considering its superior performance characteristics in many areas, such as chemical resistance and temperature tolerance, the extra cost might be worth it depending on your application requirements.
