Machining PF CP 201 (Hp 2061)

PF CP 201 is the EN 60893 designation for the phenolic paper laminate known under the older DIN 7735 standard as Hp 2061 – technically the same material. It consists of phenolic resin reinforced with cellulose paper and is the economical standard grade (NEMA X/XP) of the phenolic paper laminate family, with good basic mechanical properties and moderate electrical insulation performance.

We machine PF CP 201 (Hp 2061) from sheets, rods or tubes using sharp, carbide-tipped tools – sawing, milling, drilling and turning are carried out cleanly and accurately. We ensure adequate dust extraction, since fine, fibre-containing resin/paper dust is generated during machining.

PF CP 201 (Hp 2061) is worthwhile whenever an economical, mechanically resilient insulating and structural material is needed for general applications in the low-voltage range – for example:

• Insulating and partition parts in low-voltage switchgear engineering
• Gears, cams and sliding elements in mechanical engineering
• Jig and fixture components
• Spacers, brackets and mechanical structural parts
• General electrical insulation parts without special requirements

Component price is mainly determined by sheet thickness or rod diameter, dimensions, material utilisation, machining effort and batch size. PF CP 201 (Hp 2061) is the most economical grade in the PF-CP series. We are happy to provide binding prices on request based on your drawing.

PF CP 201 (Hp 2061) is not declared suitable for direct food contact. For higher dielectric strength requirements, PF CP 202 (Hp 2061.5) is the better choice; for flame retardancy to UL 94 V-0, PF CP 204 (Hp 2063) is recommended. The material is also unsuitable for continuous use above approximately 120 °C or in damp environments, since the paper reinforcement is hygroscopic.

An honest assessment – and how the disadvantages can be mitigated in practice:

• Advantage: Economical standard-grade paper laminate, most widely used grade
• Advantage: Good basic mechanical properties
• Advantage: Thermoset, dimensionally stable
• Advantage: Good machinability
• Advantage: Proven, widely used material
• Disadvantage: Not declared suitable for direct food contact
• Disadvantage: Moderate comparative tracking index (CTI 100) – unsuitable for higher electrical requirements
• Disadvantage: Paper reinforcement absorbs moisture
• Disadvantage: Continuous use limited to approx. 120 °C
• Disadvantage: Not flame-retardant (standard grade)
• Practical tip: PF CP 201 (Hp 2061) is the right choice for economical, mechanically resilient insulating and structural parts in the low-voltage range without special requirements. If higher dielectric strength is needed, PF CP 202 (Hp 2061.5) is the better choice; for flame-retardancy requirements, PF CP 204 (Hp 2063) is recommended.
