יריעת פוליאמיד ®Cirlex
טכנולוגיית הפוליאימיד Cirlex® פותחה על ידי DuPont כדי לספק לתעשייה מגוון של יריעות פוליאמיד עבות מהסטרנדט המקובל. לחומר יתרון עמידות בטמפרטורות גבוהות של מקסימום כ 400 מעלות צלזיוס ויכולת עמידות החומר ושמירה על התכונות המכניות והחשמליות עד טווח זה
Cirlex® polyimide technology has been developed by DuPont to provide industry with a variety of thick polyimide sheets above the availability of Kapton® film. Cirlex® is an all polyimide, adhesive-less laminate. Cirlex® can operate routinely in a temperature range from cryogenic to a maximum of 400°C. It also exhibits excellent physical, dielectric and mechanical properties similar to that of Kapton® HN film
CIRLEX® is offered in thicknesses from 0.015mm (0.006”) to 4.0mm (0.157”). Thicker constructions are possible. CIRLEX® can be subjected to laser cutting, drilling, machining, stamping, shearing and chemical etching.
Applications:
- PCB stencils
- Loudspeaker components
- Metal clad, thick polyimide materials
- Slot insulation
- High-density electronic connectors
- High-temperature mechanical seals
Availability:
CIRLEX® is available in standard sheet. Stock sizes are nominal 600mm x 600mm or 300mm x 300mm.
