Conductive Acetal Copolymer (CN-SS) Specifications

Description

Stainless-steel-fiber-filled, non-sloughing, dimensionally stable material HDT @ 264 psi of 225° F. This material has relatively high chemical resistance, is extremely strong and stiff, and is an excellent choice for situations where carbon-based conductive fillers are not acceptable. Easily machined with carbide-tipped tooling to tight tolerances.

Applications

Disk drive assembly fixtures • Semiconductor/electronic components • Telecommunication hardware • Automotive equipment

Advantages of Conductive Acetal Copolymer (CN-SS)

Low outgassing • Consistent resistivity values • Ease of machining • Good chemical resistance

Manufacturing Capabilities

Rod: 1/8” to 4” diameter • Sheet: 1/4” to 4” thick

Color/Grades
