HTPB i hoʻohenehene ʻia CAS 69102-90-5 i hoʻopau ʻia i ka pūʻulu hydroxyl hydrogenated polybutadiene.
HTPB he wai polimer maiuu mamao, ʻo ka ʻili wai hou. ʻOkoʻa nā waiwai no ka mea he hui ʻia ʻo HTPB ma mua o kahi hui maʻemaʻe, a ua hana ʻia ia e hoʻokō i nā koi kikoʻī o nā mea kūʻai aku. ʻO ka HTPB maʻamau ʻo R-45M me kēlā me kēia hopena o ke kaulahao i hoʻopau ʻia me kahi hui hydroxyl [OH]. i kēia manawa hiki iā mākou ke hana i ka hoʻolālā hou e like me kaHTPB me hoʻokahi -OH no ke kaulahaoaManaʻo waihā.
No ka meaHTPB waihā(Hydrogenated Hydroxyl Group-Terminated Polybutadiene/ Hydrogenated Hydroxyl Terminated Polybutadiene(HTPB) is hydrogenated homopolymers of butadiene,
ʻO lāua ka hopena hydroxyl pūʻulu i hoʻopau ʻia a kūpono no ka hoʻohana ākea. Ma muli o ka saturation o ka hui 1,2-vinyl i kēia mau polybutadienes i loaʻa i ka paʻa kemika lōʻihi loa.
me na waiwai e like me:
1. ʻO ke ʻano maʻalahi loa
2.Hydrophobicity
3.Low dielectric mau
4.Good kemika kū'ē
5.Reactive hydroxyl pūʻulu
6.Long-manawa kūpaʻa
hiki ke hoʻohana ʻia e like me ka resin modifiers, urethane resins (pena, adhesives, coating agents), uila insulating mea, TPU elastomers
kā mākou HTPB waihākikoʻī e like me ka hahai ʻana (eia kekahi: Hiki iā mākou ke noiʻi a hoʻomohala i kekahi mana hou o HTPB e like me ke koi kūikawā o kā mākou mea kūʻai aku)
