A rubber plasticizer is a reagent. The plasticization of rubber refers to the addition of certain substances in the rubber, which can reduce the force between the rubber molecules, thereby reducing the glass transition temperature of the rubber, making the rubber plasticity, fluidity, and facilitating the forming operations such as calendering and pressing. It can improve certain physical and mechanical properties of vulcanizates, such as lowering hardness and modulus, giving higher elasticity and Bokiti ya molunge ya nse, mpe kobongisa résistance ya malili.

It can improve certain physical and mechanical properties of vulcanizates, such as lowering hardness and modulus, giving higher elasticity and lower heat generation, and improving cold resistance.
Plasticization of rubber can be done by physical and chemical methods. Chemical plasticization, including plasticizing and plasticizing in various plastics, is a process in rubber processing. In the case of synthetic rubber, the plasticization is introduced into the rubber molecular chain by chemical reaction to increase the flexibility of the molecular structure to achieve plasticization. . Chemical plasticization does not lose its effect due to the volatilization or precipitation of the plasticizing material, and the plasticizing effect is long-lasting and Na ndenge wana ezwi likebi mingi. Plasticisation physique ezali kolobela ntina ya plastifiant na nzela ya biloko mosusu. oyo babengi plasticisation ezali kolobela plasticisation physique, mpe eloko oyo ebakisami na plasticisation physique babengaka yango kolɛmbisa plasticizer.
Ba plastifiants oyo e adoucir caoutchouc e classifié mingi mingi na ba adouciants na ba plastifiants selon polarité na bango pe usage. ezuami na ba substances naturelles pe babengaka yango adoucisseur pona caoutchouc non polaire. Esalemaka mingi mingi lokola plastifiant pona caoutchouc polaire to plastique. oyo eyebani lelo na industrie lokola ba plastifiants.
Plasticisateur esengeli a répondre na ba conditions oyo na tango ya production mpe na usage : Effet plastifiant ya malamu, dose ya moke, absorption rapide, compatibilité ya malamu na caoutchouc, volatilité ya moke, migration ya malamu te, résistance ya malili malamu, résistance na mayi, résistance ya mafuta mpe résistance. solvant, résistance ya chaleur ya malamu, résistance ya lumière, isolation électrique ya malamu, résistance ya flamme ya malamu, résistance ya bactéries, ya malamu te{2}
Kasi, ezali mpenza mpasi mpo na kozala na plastifiant oyo ekokisaka mpenza makambo oyo ezali awa na likoló. Yango wana, na kosalela yango mpenza, ba plastifiants mibale to mingi esalelami elongo mpo na kofuta moko na mosusu. motuya ya plastifiant elobelami mingimingi lokola plastifiant principal, mpe mosusu babengaka yango plastifiant auxiliaire.
Type ya plastifiant ekoki pe ko classifier na plastifiant ya pétrole, plastifiant ya goudron ya charbon, plastifiant ya mafuta ya pin, plastifiant ya mafuta pe plastifiant synthétique selon source.
