moderate mechanical strength, stiffness and creep resistance
very good electrical insulating and dielectric properties (virgin grades only)
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 CESTIFLAME)

Applications

Gears; bearings; wear plates; support-, tension- and deflecting rollers; rope pulleys; chain sprockets; guide strips for conveyor belts and chains; bumpers; scraper blades; piston rings and packings; seals; valves; hammerheads; conveyor screws; star wheels and bends; pumps; filter plates; electroplating drums; pickers; beater caps; linings for bunkers, silos, chutes and funnels for bulk materials; punching plates; cutting and chopping boards; …

CESTILENE HD500 (now PE 500) (PE-HMW)

Natural (white) / black - Molecular weight of about 500,000 g/mol.

This grade exhibits a good combination of stiffness, toughness, mechanical damping ability with wear- and abrasion resistance and can easily be welded. CESTILENE HD500 (now PE 500) is a versatile polyethylene grade used mainly in the food industry (meat and fish processing) but it is also put to use in all kinds of mechanical, chemical and electrical applications.

Cestilene HD1000 (now TIVAR 1000) (PE-UHMW)

Natural (white) / black / green - Molecular weight of about 5,000,000 g/mol.

Of all ultra high molecular weight polyethylene grades, Cestilene HD1000 (now TIVAR 1000) exhibits the best balanced property profile. It combines an excellent wear and abrasion resistance with an outstanding impact strength, even at temperatures below -200°C. Its main fields of application are: general mechanical construction; bottling-, canning- and packaging machinery; chemical and electroplating industry; cryogenic equipment; textile industry and storage systems for bulk materials.

CESTIDUR (now TIVAR DS grey) (PE-UHMW)

(Blue grey) - Molecular weight of about 7,000,000 g/mol.

The higher molecular weight and the particular manufacturing process of this material result in a PE-UHMW grade with superior wear and abrasion resistance. Cestidur (now TIVAR DS grey) has proven to be able to deal with the toughest bearing and wear jobs in all kinds of industries.

CESTILITE ASTL (now TIVAR 1000 ASTL) (PE-UHMW + additives)

(Black) - Molecular weight of about 9,000,000 g/mol.

CESTILITE ASTL (now TIVAR 1000 ASTL) has been specifically developed for the toughest anti-abrasion applications. The additives used also confer this material static dissipative and UV-stabilised properties. This reduces the risk of explosions when handling certain bulk materials on the one hand and make the material suitable for outdoor use on the other hand.

CESTITECH 7000 (now TIVAR TECH 7000) (PE-UHMW + additives)

(Grey-black) - Molecular weight of about 9,000,000 g/mol.

This grade, made from a PE-UHMW resin with extremely high degree of polymerisation, contains specific additives which result in a material with very good wear resistance and sliding properties. Its particular manufacturing process (high pressure and very long sintering cycle) results into stock shapes with low internal stress level and excellent overall quality
