Neoprene (CR)
Neoprene, Polychloroprene is composed of chloroprene monomer polymerization. After vulcanization, it has good rubber elasticity and abrasion resistance. It is anti-insolacija and has good weather resistance, resistant to violent distortion, refrigerants, dilute acid, silicon ester lubricant, but not resistant to phosphate series of hydraulic oil. It is easy to crystallize and harden at low temperature, weak storage stability, and big expansion in low aniline point of mineral oil. In using temperature range is - 50 ~ 150 degree.
Prednosti:
Good elasticity and good compression deformation, the formula contains no sulfur, so it is very easy to operate. It has anti-animal and vegetable oil properties, will not be affected by neutral chemicals, fats, oils, a variety of oils, solvents, and also has anti-fire properties.
Nedostaci:
Do not recommend to use in strong acids, nitrohydrocarbons, esters, chloroform and ketone chemicals.
primjena:
Rubber parts or sealing parts with R12 refrigerant, household appliances. Suitable for rubber products which direct contact with the atmosphere, sunlight, ozone parts, resist fire and chemical corrosion.
Certifikat:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS

Nitrilna guma ima dobra svojstva samoekspandiranja, otpornost na habanje i svojstva otpornosti na ugljovodonike. Može se koristiti kao opći materijal za vodu, vakuum, kiselinu, sol, alkalije, mast, ulje, puter, hidraulično ulje, glikol, itd. Ne može se koristiti na mjestima kao što su aceton, keton, nitrati i fluorirani ugljovodonici. |
| EPDM |
-40℃~135℃ Instant -50℃~150℃ |
Etilen-propilen guma je dobra sintetička guma-opšte namjene koja se može koristiti u sistemima tople vode, napitcima, mliječnim proizvodima, ketonima, alkoholima, nitratima i glicerinom, ali ne i u uljima na bazi ugljovodonika, neorganskim tvarima ili rastvaračima.
