Machining PF CP 206 (Hp 2062.8)

PF CP 206 is the EN 60893 designation for the phenolic paper laminate known under the older DIN 7735 standard as Hp 2062.8 – technically the same material. As NEMA type XXXP, it is the mechanically more robust of the two pure punching grades in the phenolic paper laminate family, designed for clean cold punching without edge cracking.

Liedtke Kunststofftechnik manufactures precision-cut, punched and formed parts from PF CP 206 (Hp 2062.8) sheets to customer drawing – sawn, milled, drilled or punched. Our quality management system, certified to DIN EN ISO 9001, ensures consistent production quality.

PF CP 206 (Hp 2062.8) is well suited whenever a punchable, mechanically robust electrical insulation material is needed:

• Punched insulating parts subject to higher mechanical loading in service than the standard punching grade PF CP 205/Hp 2062.9
• Components in electrical and switchgear engineering that require punchability at room temperature
• Applications where good electrical insulation and documented impact strength are both required
• An economical alternative to hot-punchable or higher-grade laminates where cold punchability is sufficient
• Insulating parts in mechanical engineering with medium to higher mechanical loading

PF CP 206 (Hp 2062.8) sits in the mid-range of the phenolic paper laminate family price-wise – somewhat above the simple standard grade PF CP 201 (Hp 2061), but well below specialty and high-performance laminates. Exact prices depend on sheet thickness, dimensions and order quantity; we are happy to provide an individual quotation.

PF CP 206 (Hp 2062.8) is not declared suitable for direct food contact. Where flame retardancy is required, PF CP 204 (Hp 2063) is the right choice, and for very high electrical loading, the electrically improved grade PF CP 202 (Hp 2061.5). For the simplest applications without particular mechanical requirements, the more economical standard grade PF CP 201 (Hp 2061) is usually sufficient.

An honest trade-off, and how the disadvantages can be mitigated in practice:

• Advantage: Punchable at room temperature (NEMA XXXP)
• Advantage: The more robust of the family's two pure punching grades
• Advantage: Good electrical insulating properties
• Advantage: Good machinability (sawing, milling, drilling, punching)
• Advantage: Economical compared to specialty and high-performance laminates
• Disadvantage: Not declared suitable for direct food contact
• Disadvantage: Not flame-retardant
• Disadvantage: Absorbs a small amount of moisture, which may cause slight changes in electrical properties
• Disadvantage: Inferior to the electrically improved grade PF CP 202/Hp 2061.5 at very high electrical test voltages
• Disadvantage: Certain characteristics (including exact limiting temperature, thermal class, water absorption) not separately documented for this grade
• Practical tip: If a punchable phenolic paper laminate with higher mechanical load-bearing capacity than the standard punching grade PF CP 205/Hp 2062.9 is needed, PF CP 206 (Hp 2062.8) is usually the right choice. If flame retardancy is also required, PF CP 204/Hp 2063 should be considered instead.
