Murtfeldt Original Material ”S”® Green Polyethylene
Categories: Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); UHMW PE (Ultra High Molecular Weight PE)

Material Notes: Material ”S”® is based on virgin, ultrahigh molecular weight low pressure polyethylene and significantly exceeds the requirements of DIN 16972. In particular, Material ”S”® green has excellent slide properties, high wear resistance, and a long lifetime It is used in all applications where a technical, high performance plastic is required.

Special Properties:
• Extremely high wear resistance –even in abrasive applications
•Excellent slide properties
• High impact strength
•Extremely good resistance to chemicals
•Excellent shock and impact absorption
•Good anti-adhesion properties
•No moisture absorption
•Electrically isolating
•Approved for use in the food industry (EU and FDA)
