Chemical Properties:

Methyl methacrylate yog cov kua uas tsis muaj xim, tsis muaj kuab lom thiab tawg. Tus txheeb ze ntom ntom 0.9440. melting point - 48 ℃. Kub taw tes 100 ~ 101 ℃. Flash point (qhib khob) 10 ℃. Refractive index 1. 4142. vapor siab (25.5 ℃) 5.33kPa. Soluble nyob rau hauv ethanol, ether, acetone thiab lwm yam organic solvents. Me ntsis soluble hauv ethylene glycol thiab dej. Yooj yim polymerized nyob rau hauv lub xub ntiag ntawm lub teeb, tshav kub, ionizing hluav taws xob thiab catalyst.

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.
