Na Waiwai Kemika:

He wai ka Styrene ma ka lumi wela, ʻaʻohe kala, me ka ʻala ʻala, hiki ke puhi ʻia ka styrene, kahi e hoʻolapalapa ai 145.2 degere Celsius, ka pae hau o -30.6 degere Celsius, gravity kikoʻī 0.906, ʻaʻole hiki ke hoʻoheheʻe ʻia ka styrene i ka wai, inā ma 25 degere Celsius, styrene ʻO ka solubility he 0.066% wale nō. Hiki ke hui pū ʻia ʻo Styrene me ka ether, methyl ferment, carbon disulfide, acetone, benzene, toluene a me ka carbon tetra-ironic i kēlā me kēia ʻāpana. He mea hoʻoheheʻe maikaʻi ʻo Styrene no ka lāʻau kūlohelohe, ka lāʻau synthetic a me nā mea hoʻohuihui he nui. He mea ʻawaʻawa ʻo Styrene a hiki ke hoʻomake i ka ʻawaʻawa inā hoʻomohu nui ke kino o ke kanaka i ka mahu styrene. ʻO ka ʻae ʻia o ka styrene i ka ea he 0.1mg/L. ʻO ka mahu Styrene a me ka ea e hana i kahi hui pahū.

Noi:

ʻO Styrene kahi monomer koʻikoʻi o ka synthetic rubber, adhesives a me nā plastics. [3,4,5] Hoʻohana ʻia ia no ka hana ʻana o ka styrene butadiene rubber a me ka resin polystyrene, polyester glass fiber reinforced plastics a me nā uhi. Hoʻohana ʻia ia no ka hoʻomākaukau ʻana i ka polystyrene, ion exchange resin, a me ka polystyrene foam. Hoʻohana ʻia ia no ka copolymerization me nā monomers ʻē aʻe e hana i nā plastic engineering like ʻole, e like me ka copolymerization o ka acrylonitrile a me ka butadiene e hana ai i ka resin ABS, hoʻohana nui ʻia i nā mea hana hale a me nā ʻoihana. ʻO ka Copolymerization me ka acrylonitrile, loaʻa iā SAN he resin me ke kūpaʻa haʻalulu a me ke kala ʻālohilohi. ʻO ka SBS i hoʻopuka ʻia e ka copolymerization me ka butadiene, he ʻōpala thermoplastic, i hoʻohana nui ʻia e like me ka polyvinyl chloride a me ka acrylic modifier. Hana ʻia nā elastomers thermoplastic SBS a me SIS me ka butadiene a me ka isoprene copolymerization, a ma ke ʻano he monomer crosslinking, hoʻohana ʻia ka styrene i ka hoʻololi ʻana o PVC, polypropylene, a me ka polyester unsaturated.
Hoʻohana ʻia ʻo Syrene ma ke ʻano he monomer paʻakikī no ka hana ʻana i ka styrene acrylic emulsion a me ka solvent pressure sensitive adhesive. Hiki ke hoʻomākaukau ʻia ka emulsion adhesive a me ka pena e ka copolymerization me ka vinyl acetate a me ka ester acrylic. ʻO Styrene kekahi o nā monomers vinyl maʻamau i hoʻohana ʻia ma ke kahua ʻepekema, i hoʻohana ʻia i nā mea like ʻole i hoʻololi ʻia a me nā mea hoʻohui.[6]
Eia kekahi, hoʻohana ʻia kahi styrene liʻiliʻi e like me ka mea ʻala a me nā mea waena ʻē aʻe. Ma ka chloromethylation o styrene, cinnamyl chloride ua hoʻohana 'ia ma ke 'ano he intermediate no ka non anesthetic analgesic ikaika eha hoʻoholo 'ia, a me ka styrene ua hoʻohana 'ia e like me ka antitussive, expectorant a me anticholinergic lāʻau kumu i loko o ka opu Changning. Hiki ke hoʻohana ʻia e synthesize i nā anthraquinones dye intermediates, pesticide emulsifiers, a me styrene phosphonic acids ore dressing agent a me nā mea hoʻonaninani keleawe.
