Polyisobutylene, PIB, yog ib qho txuj ci tseem ceeb polymer tsim los ntawm qhov zoo ion polymerization, uas tau qhia nws qhov kev ua tau zoo hauv ntau yam. Qhov hnyav molecular PIB1300 thiab PIB2400, nrog rau qhov hnyav molecular li ntawm 200-10,000 thiab 20,000-45,000 feem, yog qhov tshwj xeeb rau lawv daim ntawv thov.
Kev siv dav dav
Tsawg Molecular Nyhav Polyisobutyleneyog dav siv nyob rau hauv cov roj additives los txhim kho cov roj kev ua tau zoo vim nws lub teeb yuag zog, thiab raws li adhesives thiab sealants muab zoo heev bonding zog rau ntau yam ntaub ntawv. Nyob rau hauv coatings thiab lubricants, lawv muab cov thickening thiab lubricating cuam tshuam, thaum li plasticizers thiab cable impregnants, lawv xyuas kom meej cov khoom durability thiab fluidity.
Rau siab molecular hnyav polyisobutylene, xws li cov uas muaj ib tug molecular hnyav nruab nrab (MWA) ntawm 75,000-600,000, lawv daim ntaub ntawv yog ntau tshaj, raws li cuam tshuam-hloov additives rau plastics, raw roj hmab, thiab thermoplastic elastomers, muab cov ntaub ntawv uas muaj zog toughness thiab cuam tshuam.
Superior kev ua tau zoo:
PIB 1300/2400yog qhov zoo tshaj plaws rau lawv cov yam ntxwv: lawv tsis muaj xim, tsis muaj ntxhiab, tsis yog - tshuaj lom, thiab cov ntaub ntawv zoo ib puag ncig nrog kev sib raug zoo nrog txhua hom hydrocarbon polymers thiab cov khoom siv organic. Lawv cov tshuaj tua kab mob antioxidant thiab UV-cov khoom tiv thaiv kom ntseeg tau ntev - ruaj khov nyob rau sab nraum zoov. Qhov zoo tshaj plaws, lawv cov plasticizing thiab tackifying zog, tshwj xeeb tshaj yog tus kheej -adhesion ntawm PIB2400, yog qhov zoo tshaj plaws. Tom qab thermal decomposition, lawv tawm tsis muaj teeb meem seem thiab yog ib puag ncig tus phooj ywg thiab nyab xeeb.
PIB1300/2400 uas tsis muaj molecular hnyav polyisobutylene, nrog nws cov kev ua tau zoo heev thiab siv dav, muab kev txhawb zog rau ntau yam lag luam thiab yog ib qho ntawm cov khoom siv tseem ceeb thiab tseem ceeb hauv kev lag luam niaj hnub no.
