General Information

Resistant to corrosion, abrasion and to most chemicals

Extremely good impact toughness and notch impact strength

High surface hardness

Resistant to hydrolysis

Insulating against moisture and electricity

This material should not be used at freezing temperatures, because of embrittlement at temperatures below 0 °C

Chemical features:

Good resistance to alcohols, ketones, alkalis and acids (except strong and oxidizing acids); resistant to fats and oils, including mineral oils and fuels.

Material specification:

PP (polypropylene) is a universally usable standard plastic with excellent properties

PP is sterilizable and has good electrical properties

Weldable; bondable only after pretreatment

PP is similar to PE (polyethylene), but more fat- and oil-resistant, and also features a higher hardness and stiffness than HDPE as well as a better resilience; its impact strength is, however, lower

UV-radiation and weather: limited resistance

Material: PP (polypropylene)

Colour: natural

Density: 0.90 g/cm3 (DIN 53479)

Temperature range: 0 to +100 °C

Elastic modulus: 1,350 N/mm2 (ISO 527)

Yield stress: 30 N/mm2 (ISO 527-1)

Tearing strength: 25 - 40 N/mm2 (DIN 53455)

Elongation at break: 70 % (DIN 53455)

Impact resistance: without break (DIN 53453)

Notch impact strength: 7 kJ/m2 (DIN 53453)

Ball pressure hardness: 70 N/mm2 (DIN 53456)

Coefficient of sliding friction against steel (dry): approx. 0.30 - 0.40

Thermal conductivity: 0.22 W/m * K (DIN 52612)

Shore hardness D: 70° (DIN 53505)

Volume resistivity: 1017 Ohm x cm (DIN 53482)

Surface resistance: 1013 Ohm (DIN 53482)

Dielectric constant: 2.27 at 50 Hz (DIN 53483)
