Polypropylene / PPC / PPH.

PPC - Polypropylene Copolymer / PPH - Polypropylene Homopolymer

Shows a high mechanical strength, tensile strength, but a low notched impact strength PP resists stress cracking and it is easy to weld. At minus temperatures it can get brittle. The chemical and electrical properties are very good. The working temperature ranges between +5 °C and 100 °C.

Advantages

• low density
• good heat resistance
• high tensile strength
• high surface strength
• high chemical resistance
• food safe

Disadvantages

• low oxidation resistance
• low abrasion resistance
• HF-welding not possible
• difficult to varnish and glue
• not weather resistant

Applications

• Pumps
• Valves
• Seals
• Toys
• Bearings
