Polymer blend with PEEK properties
Polymer blend with PEEK properties
(OP)
Hi all, we are a small enterprise, and we are trying to get a polymer blend with PEEK 150 G similar properties, so we would like to know if there are any polymer similar to PVDF that we can blend with PEEK and mantain his mechanical and chemical properties.
Thanks in advanced

Can you rephrase, possibly with the help of someone with better English skills.

RE: Polymer blend with PEEK properties
For aeronautic applications, the main thermoplastic engineering polymer used is the PEEK. This polymer offers interesting properties:
- High temperature resistance
- Excellent resistance to a wide range of organic and inorganic chemicals
- Excellent mechanical properties at high temperature and in rigorous environment
- Good fire resistance
But, PEEK has a very melting point (343 ºC) and as a consequence a very high processing temperature (around 400 ºC) that requires a lot of energy for processing and the use of costly environment products.
The objective of this proposal is to develop a thermoplastic matrix with a lower processing temperature than PEEK for composite applications in aeronautic, also the mechanical and physic-chemical properties will be similar to the PEEK properties.. The polymer blend will have a processing temperature under 300 ºC and a glass transition higher than 140 ºC.
The doubt is if anyone can help us to find a polymer which we can use to blend with PEEK or with other polymer and obten similar properties to PEEK.
Thanks in advanced

thanks for your help and patience

What's wrong with nylon 6.6? Fulfils all your criteria given so far. (Peek also has other beneficial) properties, of course.
Why do I get the feeling you have too much time on your hands?
Have you ever thought that if what you want is possible, then all the polymer companies in the world would be making it?

What you ask is impossible. Pat and Pud have given you your best option.

Thermosets have a HDT higher than their processing temperature, but mostly lack in some other properties.
I am not convinced PEEK is the main engineering plastic used in aeronautical.
Aircraft interiors use a lot of ABS and PC/ABS and lots of mechanisms use nylon. Windows are acrylic. Many structural parts are now epoxy/carbon fibre.
A more accurate statement might be that most PEEK sales are to aerospace.

Our intention is to be the first company to make it, because we are a R&D center, anyway thank all of you for your replies and i will continue working on it
Best regards

It's only remained expensive because for a while Victrex had a virtual monopoly.

I'm speaking out of ignorance with regards to your application but have you looked at other ketones like PEKK?
