SAATIMOTIONPEEK fabrics for automotive applications

Poly ether ether ketone (PEEK) is a thermoplastic semi-cristalline polymer belonging the Polyary-letherketone (PAEK) family, characterized by outstanding properties which are maintained even at high temperature.

Thermal Properties

SaatiMotion Peek Fabrics are characterized by a melting point around 320°C and a glass tran-sition temperature around 156°C. Due to this they could be used as an alternative to wire mesh for high temperature application where standard synthetic fabrics fail.

Chemical Resistance

SaatiMotion Peek Fabrics show a very high che-mical resistance, even at high temperature. Only concentrated strong acids like sulphuric and nitric acids are capable to dissolve PEEK.

Mechanical Resistence

SaatiMotion Peek Fabrics are characterized by a high mechanical properties, especially in terms of wear and friction resistance.

Hydrolysis Resistance

SaatiMotion Peek Fabrics are suitable for ap-plications in which a significant hydrolysis re-sistance is required. Steam and high pressure water do not affect fabric mechanical proper-ties, even after a long exposure.

Due to their properties PEEK fabrics are ideal for filtration application as substitution of traditional filter media, such as PA, PES, PP or Wire mesh. Below a typical PEEK fabric application in automotive filtration:

Injector filters

Typically injector filters are realized using PA mesh or Wire mesh. Both these solutions show potential limitations:• wire mesh could grant high temperature and chemical

resistance, but on the on the other hand it has poor fa-tigue resistance and requires expensive and dedicated toolings for injection molding process.

• PA mesh on the other hand has the tendency to swell when in contact with hot fuels and it shows poor resi-stance with particular bio fuel blends, which could lead to in filed failure and damage.

PEEK fabrics are the ideal solutions for this applications, since they could match chemical, thermal and mechanical proper-ties of wire mesh with the easiness of handling of synthetic materials.

Other applications:• Screen for resonator: depending on the air intake configuration it could be important to have a

fabric with an enhanced chemical resistance to protect the sound dampening system.• Oil filter bypass: typically oil filter bypass are made of PA or PES mesh. In case a long exposure

to high temperature is required (>150°C), PEEK fabrics are the solution to grant the filtration performances over the entire life of the filter.
