Chemical Properties:

Methyl 2-methyl-2-propenoate muaj cov ntxhiab tsw ntxhiab tsw. Nyob rau hauv lwm daim ntawv qhia no compound yog qhia kom muaj ib tug ntse, fruity tsw.Methyl methacrylate yog ib tug methyl ester ntawm methacrylic acid. Nws yog ib tug tsis muaj kob, volatile kua nrog ib tug acrid fruity tsw. Nws muaj qhov siab vapor siab (4 kPa ntawm 20 ° C), dej solubility nruab nrab (15.8 g / liter), thiab qis log octanol / dej faib coefficient (Kow = 1.38). Methyl methacrylate feem ntau yog 99.9% ntshiab thiab muaj me me ntawm inhibitor rau retard polymerization.

Daim ntawv thov:

1.Methyl methacrylate yog ib yam khoom siv hluav taws xob tsis zoo uas yog siv los tsim cov ntawv cam khwb cia acrylic, acrylic emulsions, thiab molding thiab extrusion resins.

2.Hauv kev tsim cov methacrylate resins thiab plastics. Methyl methacrylate yog transesterified rau hauv siab dua methacrylates xws li n-butyl methacrylate los yog 2-ethylhexylmethacrylate.

3.methyl methacrylate monomer yog siv nyob rau hauv zus tau tej cov methylmethacrylate polymers thiab copolymers, polymers thiab copolymers kuj siv nyob rau hauv waterborne, hnyav, thiab undissolved nto txheej, nplaum, sealants, tawv thiab ntawv txheej, inks, pem teb polishes, textile finishes, kho hniav prostheses, phais pob txha cements, thiab leaded acrylic radiation shields thiab nyob rau hauv kev npaj ntawm hluavtaws ntiv tes thiab orthotic khau inserts. Methyl methacrylate kuj tseem siv los ua cov khoom pib los tsim lwm cov esters ntawm methacrylic acid.

4.Granules rau txhaj tshuaj thiab extrusion tshuab moulding uas rau lawv qhov zoo tshaj plaws optical clarity, huab cua thiab khawb kuj yog siv nyob rau hauv lub teeb pom kev zoo, chaw ua hauj lwm cov cuab yeej thiab electronics (cov xov tooj ntawm tes thiab cov khoom siv hi-fi), lub tsev thiab kev tsim kho (glazing thiab qhov rais thav ntawv), kev tsim qauv. (furniture, jewelery thiab tableware), tsheb thiab tsheb thauj mus los (teeb thiab ntsuas vaj huam sib luag), kev noj qab haus huv thiab kev nyab xeeb (jars thiab test tubes) thiab cov khoom siv hauv tsev (microwave qhov cub qhov rooj thiab mixer tais).

5.Impact modifiers rau ntshiab rigid polyvinyl chloride.
