Main Characteristics:
- Very good wear and abrasion resistance
- High impact strength, even at low temperatures (particularly PE-UHMW)
- Excellent chemical resistance
- Low density compared with other thermoplastics
- Low coefficient of friction
- Excellent release properties
- Very low water absorption
- Moderate mechanical strength, stiffness and creep resistance
- Very good electrical insulating and dielectric properties (except static dissipative grades)
- Excellent machinability
- Physiologically inert (several grades are suitable for food contact)
- Good resistance to high energy radiation (gamma- and X-rays)
- Not self-extinguishing (except TIVAR Burnguard)
Grade Information:
TIVAR H.O.T. bright white [PE-UHMW + specific additives]
TIVAR H.O.T. [Higher Operating Temperature] is formulated to maintain inherent PE-UHMW key properties over an extended service temperature range, in this way considerably increasing part life in low load bearing applications up to temperatures as high as 125°C. Special additives reduce the oxidation rate of the material at higher temperatures thereby slowing down material degradation and extending wear-life. TIVAR H.O.T. also features a food contact compliant composition.
