Washer (DIN 433) made of PP
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
