Opis:

1,PEEK（polyether-ether-ketone）， is crystalline thermoplastic polymer material with a melting temperature of 334℃. Has advantages of high mechanical strength, high temperature resistance, impact resistance, flame retardancy, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance and good electrical properties.

2,Has a higher melting point(334℃) and glass transition temperature(143℃), continuous use temperature of 260℃.

3,The accepted standard for measuring flammability of materials is UL94, and the result of PEEK is V-0, which is the best level of flame retardancy.

4,Excellent fatigue resistance to alternating stress comparable to alloy materials.

5,PEEK is widely used in aerospace, automotive, electrical and electronic, medical and food processing.

PPSU is polyphenylene sulfide ,a kind of thermoplastic special engineering plastic with excellent comprehensive performance.Its outstanding features are high temperature resistance,corrosion resistance and superior mechanical properties.

Primjena:

PEEK-ov dugoročni radni temperaturni raspon od -100℃ do +250℃, naširoko se koristi u zrakoplovnoj, medicinskoj, farmaceutskoj i prehrambenoj industriji, kao što su strukturne komponente analizatora plina na satelitima, lopatice izmjenjivača topline, njegova vrhunska otpornost na trenje čini ga idealan materijal za primjene trenja kao što su valjkasti ležaji, klizni ležajevi, sjedišta ventila, brtve i habajući prstenovi pumpe.

Glavna upotreba PPSU-a je u području elektroničkih uređaja, kao što je izrada kostura transformatora, visokofrekventnih zavojnica, utikača, utičnica, okvira za ožičenje, bubnjeva kontaktora i raznih preciznih dijelova.
