The following graph shows the increase in volume of all Calvo Sealing’s elastomers to attacked by oils.
Hardness (Shore A) 60 ºElongation 400 %Tensile Strenght 9 N/mm2
Temperature Range -40 ºC to 135 ºC (-40 ºF to 275 ºF)
PROPERTIES• Impermeable to gas and air. • Excellent resistance to oxidation and ozone.• Low resilience, that provides outstanding impact damping capacity. • Good electrical resistance.
APPLICATIONS
• Where an excellent gas-tightness is required. • Resistant to most chemicals, including mineral acids.• It is not suitable for use with oils and hydrocarbonated solvents.
Hardness (Shore A) 60 ºElongation 225 %Tensile Strenght 8 N/mm2
Temperature Range -70 ºC to 220 ºC (-94 ºF to 428 ºF)PROPERTIES
• Completely unalterable by ozone, weathering and ultraviolet radiation. • Good electrical insulating properties.• Physiologically inert, ideal for field of medicine applications.
APPLICATIONS
• Where oils, water and ozone resistance is required.• This material offers excellent properties to high and low temperatures.
Hardness (Shore A) 70 ºElongation 165 %Tensile Strenght 5 N/mm2
Temperature Range -30 ºC to 250 ºC (-22 ºF to 482 ºF)PROPERTIES
• Exceptional resistance to temperature.• Excellent resistance to acids and alkalis (even oxidisers)• Weak resistance to esters and ketones.• Excellent resistance to ozone and weathering.
APPLICATIONS• Resistant to acids and alkalis, aliphatic, aromatic and chlorated hy-
