Ngec ikom jami ma ki lwongo ni Rubber Knowledge III: Styrene-Butadiene Rubber (SBR)
Styrene-Butadiene Rubber (SBR pi lok macek) obedo rubber ma ki yubu ki dul ma ki lwongo ni copolymerization pa styrene ki butadiene. En tye i kin jami ma ki yubu ki jami ma ki yubu ki dano ma pol loyo i wilobo, ma tye ki 50% pa jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki dano. Kit ma en tye kwede tye i kin pa yat ma ki lwongo ni natural rubber (NR) ki butadiene rubber (BR), ki en ki ngeyo pi tek ne maber, wel ne lapiny, ki tek ne maber.
| Nature | Fjami | Poro ki yat ma ki lwongo ni natural rubber (NR) |
| Gengo buru | Ber loyo NR, ber pi jami ma kelo peko madwong (ma calo tyen motoka) | Kit ma NR twero juku kwede jami ni nok. |
| Adegi | Gin ma gengo two ki ozone tek loyo NR (pi tye pa benzene rings) | NR twero dongo oyotoyot ki mito ni ki med iye jami ma gengo dongo. |
| Kit ma en twero loko kwede ki kelo lyeto | Kit ma ki loko kwede tye piny manok ki pa NR, ki kit ma lyeto ma ki kelo ni tye malo (kit ma ki yubu kwede omyera ki yub maber) | NR tye ki teko maber ki kelo lyeto manok. |
| Lteko me lyeto
| Lyeto ma lapiny miyo bedo tek (ka peko ni tye marac, ci styrene ma tye iye dwong). | Lyeto ma piny miyo bedo tek. (Styrene NR tye ki teko maber me gengo ngiico (-50°C bedo ma goro)) |
| Rubber adhesiveness | Bedo maber i komi kekeni; mito tic ki gin ma ki lwongo ni adhesive enhancer resin. | NR tye ki jami maber ma mako kome kene. |
| Wel cente ma mite | tung ping | Ma malo (ki balo ki kit ma piny tye kwede) |
Styrene-butadiene rubber tye ki rwom ma malo i lok ma mako tyen motoka, miyo tyen motoka bedo ki tek me buru, gengo tii ki mako maber. Medo ikom meno, ki tiyo kwede i: jami ma ki tiyo kwede i motoka (gin ma umu, jami ma gengo yamo, ki mukene), jami ma ki yubu i gang tic (gin ma tero jami, Gin ma ki lwongo ni Sealing Rings, ki mukene), jami me gedo (karatac ma pii pe romo donyo iye), jami me ot yat (jami me ot yat, gloves, ki mukene), jami ma mako ki umu, ki mukene.
Luyub jami madongo i wilobo: Sinopec, PetroChina, Lanxess, Trinseo, Asahi Kasei, ki mukene.
Jami ma ki yubu tye iye O-rings ki jami ma ki yubu pi luwil.
