Machining Guidelines

Recommended Parameters:

Turning

• Cutting speed: 200-300 m/min
• Feed rate: 0.1-0.3 mm/rev
• Use sharp tools with positive rake angles

Milling

• Spindle speed: 500-1500 RPM

• Climb milling preferred

Drilling

• Use polished flute drills
• Reduce feed near breakthrough
• Peck drilling for deep holes

General Tips

• Coolant optional but recommended for precision work
• Support workpiece to prevent deflection
• Deburr edges after machining
• Allow stress relief before final machining

Frequently Asked Questions (FAQ)

What is the maximum temperature PP Rod can withstand?

PP Rod can operate continuously at temperatures up to 100°C (212°F). For short-term exposure, it can handle temperatures up to 140°C (284°F).

Is PP Rod suitable for food contact applications?

Yes, our Röchling PP Rods are FDA compliant and EU 10/2011 certified, making them safe for food contact applications.

Can PP Rod be welded?

Absolutely. PP can be welded using hot gas welding, extrusion welding, or heated tool welding. It's one of the easiest plastics to weld.

What is the difference between PP-H and PP-C?

PP-H (Homopolymer) offers higher stiffness and better chemical resistance, while PP-C (Copolymer) provides superior impact resistance, especially at low temperatures.

How does PP compare to HDPE?

PP has higher rigidity, better temperature resistance, and superior resistance to oils and greases. HDPE offers better impact strength and stress crack resistance.

What chemicals can damage PP?

PP has limited resistance to strong oxidizing acids, chlorinated solvents, and aromatic hydrocarbons. Always verify chemical compatibility for specific applications.

Can PP Rod be used outdoors?

Standard PP has limited UV resistance. For outdoor applications, we recommend UV-stabilized grades or protective coatings.

What is the minimum order quantity?

We have no minimum order for standard stock items. Custom sizes may require MOQ – contact us for details.
