Bakelite Plate (Orange / Black) Phenolic Laminate
Paper-phenolic plate for panels, tags and mechanical parts. Bakelite (paper-phenolic) plate is the classic insulating panel material, supplied orange or black. It machines and engraves well for tags and panels. We cut and machine it to the panel or part drawing. Both are paper-phenolic; color is usually for identification or panel look. We stock both. Machinable phenolic plate for mechanical insul

Why phenolic laminate (bakelite) for this application
Phenolic plate is the low-cost rigid insulator used where the duty is LV/panel-level and the part mainly isolates and carries terminal hardware. The orange grade signals electrical duty; the black grade suits mechanical plus insulation.
Paper-core phenolic tracks if crossed under moisture — keep CtI in mind. Confirm grade (XX/XXX) and thickness tolerance before cutting punching patterns.
Standards: ASTM D709 (phenolic), IEC 60893-3-4, UL 94 HB/V-0.
Feature and remaining-wall review
ID/OD turned; CNC drilling and punching for mounting holes. Review feature depth, edge distance and remaining wall against critical geometries. Capability is confirmed on your drawing, not from a blanket tolerance.
Inspection and traceability
We state the control plan with you. Batch traceability links raw material lot to finished part.
- First-article inspection (FAI) per your plan
- In-process dimensional checks at every station
- Batch certificate of conformance (COA) supplied on request
- Lot traceability to incoming material certificate
- Dielectric strength and insulation resistance testing available on request

Common questions
Is it flame retardant?
Yes, meets UL 94 V-0 in standard grades.
What applications suit bakelite?
Terminal blocks, insulating plates, low-cost structural parts where thermal exposure is limited.
Can it be machined?
Yes — CNC drilling, punching and turning. Sharp tools prevent chipping.
What standards apply?
ASTM D4909 (phenolic), UL 94 V-0.
Orange or black bakelite?
ASTM D4909 (phenolic), UL 94 V-0.
