﹛ The Mediums of Tightening and their Qualities

Perbunan
(Nitrilcaoutschouc) NBR
Perbunan is of high resistance against oil, small concentrated solvents and many other mediums. Because of its high tightness it is also very suitable for gasvolumed fluids. Perbunan may be used at temperatures between 253K and 373K (-20∼C and +100∼C). It may not be used for some different types of hard-flamable hydraulic fluids.

PTFE
(Polytetrafluoräthylen)
PTFE is resistant against even all fluids, independent if it is solvents, lyes, acids or other fluids or gas. It has excellent qualities of glide and is suitable for a wide range of temperature from 173K up to 473K (-100∼C and +200∼C). When being used in the high pressure area it is not recommended for more than 100 bar.

Viton®
(Fluorelastomer/FPM)
Viton® is resistant against oils, fuels, solvents, acids and other aggressive fluids. The very good weather resistance is to emphasize. Dependent on purpose, Viton® may be used at temperatures from 243K up to 473K (-30∼C to +200∼C).

EPDM
(Ethylen-Propylen-Terpolymer)
Also known as APTK. EPDM is extremely resistant against light, ozone, weather and ageing. Can be recommended for use with acids (acc. to concentration), alkali, water, alcohol and cetone. Temperature range from -50∼C to +130∼C

Hypalon®
(Chlorsulfonyl-Polyethylen-Caoutschouc/CSM)
Elastic rubber with excellent resistance against all kinds of weather influences and extreme resistance against oxidizing chemicals, heat and rub off. Temperature range from -40∼C to +160∼C.

Ohasil 70
(silicon modified EPDM-Terpolymerisat)
High mechanical bearing at low and high pressure. Thermic pattern of a Silicon-rubber-quality. Excellent weather- and steam-resistance at low pressure deformation. To be used up to +195∼C working temperature, +200∼C short maximum temperature.

Shore hardness according to DIN 53505 A
28∼ to 38∼ 每 very soft
40∼ to 50∼ 每 soft
52∼ to 66∼ 每 midddle soft
68∼ to 78∼ 每 middle hard
80∼ to 90∼ 每 hard
92∼ to 100∼ 每 very hard
