Synthetic Rubbers: Details Properties, Advantages, uye Applications

1. Fluororubber (FKM)

• Properties:

• Kunyanya kupisa kwekushisa (-20 ° C kusvika +250 ° C).

• Kupokana kwakasarudzika kumafuta, mafuta, zvinonyungudutsa, acids, uye mabhesi.

• High tensile simba, low compression set, uye yakanakisa kugadzikana kwemakemikari.

• Murazvo-resistant uye ozone-inodzivirira.

• Zvakanakira:

• Inoshingirira makemikari ane hukasha uye nepamusoro-soro nharaunda.

• Hupenyu hurefu hwesevhisi mune aerospace uye mota application.

• Applications:

• Zvisimbiso zvemafuta endege, O-mhete, uye gaskets.

• Zvisimbiso zvekutakura mota, hose dzeinjini, uye turbocharger zvikamu.

• Chemical processing equipment linings uye gaskets.

2. Chloroprene Rubber (CR)

• Properties:

• Pakati nepakati mafuta kuramba (zviri nani pane yakasikwa rabha asi isingasviki FKM).

• Flame retardant ine kuzvidzimisa zvinhu.

• Kuramba kwakanaka kwemamiriro ekunze (UV, ozone, uye mwando).

• Inochinjika pakudziya kwakaderera (-40°C kusvika +120°C).

• Zvakanakira:

• Inodhura-inoshanda nekugadzirisa nyore (extrusion / molding).

• High mechanical simba uye abrasion resistance.

• Applications:

• Wet masutu, magirovhosi, uye maindasitiri hoses.

• Adhesives yeshangu uye kuvaka.

• Cable jackets uye denga membranes.

3. Hydrogenated Nitrile Rubber (HNBR)

• Properties:

• Kuwedzera kupisa kwekudzivirira (kusvika +150 ° C) zvichienzaniswa neNBR.

• Kunyanya kupikisa mafuta, hydraulic fluid, uye amines.

• High tensile simba uye kuneta kuramba.

• Low permeability kune magasi.

• Zvakanakira:

• Inochengetedza elasticity pasi pekuratidzwa kwenguva refu kumakemikari ane hutsinye.

• Hupenyu hurefu kupfuura NBR mumamiriro akanyanya.

• Applications:

• Oiri uye gasi kuchera maturusi (packers, zvisimbiso).

• Mabhandi enguva yemotokari, jekiseni remafuta, uye turbocharger seals.

• Industrial hydraulic cylinders.

4. Silicone Rubber (VMQ)

• Properties:

• Ultra-wide tembiricha range (-60°C kusvika +200°C).

• High elasticity (kusvika 1000% elongation).

• Yakanakisa magetsi ekudzivirira uye kugadzikana kwekupisa.

• Biocompatible uye inert.

• Zvakanakira:

• Inochengetedza kuchinjika mu cryogenic uye yakakwirira-tembiricha nharaunda.

• Inopesana neUV, ozone, uye mamiriro ekunze.

• Applications:

• Zvishandiso zvekurapa (catheters, implants).

• Electronic components (insulators, keypads).

• High-tembiricha gaskets ovheni uye injini.

5. Fluorosilicone Rubber (FVMQ)

• Properties:

• Inosanganisa FKM yemakemikari kuramba uye kushanduka kweVMQ.

• Tembiricha yakasiyana: -50°C kusvika +230°C.

• Inopesana nemafuta, mafuta ekuzora, uye hydraulic fluid.

• Low compression set uye yakanaka kusimba.

• Zvakanakira:

• Inoita mune zvose zviri zviviri zvepamusoro-tembiricha uye yakaderera-yakadzika yakanyanyisa.

• Kudzivirira kuzvimba mumafuta ekufambisa ndege.

• Applications:

• Zvigadzirwa zvemafuta endege (mavharuvhu, zvisimbiso).

• Deep-sea submersible gaskets uye connectors.

• Mota sensors uye emission control system.

6. Ethylene Propylene Diene Monomer (EPDM)

• Properties:

• Yakanakisa ozone uye kusagadzikana kwemamiriro ekunze.

• High dielectric simba uye kudzivirira mvura.

• Kupisa: -50 ° C kusvika +150 ° C.

• Low gasi permeability.

• Zvakanakira:

• Yakanyanya kudhura-inoshanda kune ekunze application.

• Yakanakisa vibration kuderedza uye kuderedza ruzha.

• Applications:

• Motator weatherstripping, radiator hoses, uye windshield seals.

• Denga membranes uye pond liners.

• Electrical cable insulation uye mabhandi ekufambisa simba.
