Material Data Sheet
Material: Techtron® HPV
Polyphenylene SulfideTechtron® HPV exhibits excellent wear resistance and a low coefficient of friction. It overcomes the disadvantages of virgin PPS caused by a high coefficient of friction, and of glass fibre reinforced PPS which can cause premature wear of the couterface in moving-part applications. Provides excellent wear and frictional behavior, excellent chemical and hydrolysis resistance and has great dimensional stability.
