Silicones muaj ntau pab yam ntxwv

Silicones muaj ntau pab yam ntxwv, xws li: [1]
Tsis tshua muaj thermal conductivity
Tsawg tshuaj reactivity
Tsawg toxicity
Thermal stability (constancy cov khoom ntau tshaj ib tug ntau ntau yam kub ntawm -100 mus 250 ° C).
Muaj peev xwm mus ua dej thiab tsim watertight cov ntsaws ruaj ruaj.
Tsis tau lo rau ntau substrates, tab sis adheres zoo heev rau lwm tus neeg, xws li iav.
Tsis them nyiaj yug microbiological kev loj hlob.
Kuj mus oxygen, ozone, thiab ultraviolet (UV) lub teeb. Qhov no tej khoom vaj tse tau coj mus rau coob leej ntau tus siv ntawm silicones nyob rau hauv kev tsim kho kev lag luam (xws li coatings, hluav taws kub tiv thaiv, glazing cov ntsaws ruaj ruaj) thiab cov automotive kev lag luam (lwm gaskets, lwm trim).
Hluav taws xob cov rwb thaiv tsev zog. Vim hais tias silicone formulated yuav electrically insulative los yog conductive, nws yog haum rau ib tug ntau ntawm cov hluav taws xob daim ntaub ntawv.
High roj permeability: sov li chav nyob (25 ° C), cov permeability ntawm silicone roj hmab rau tej gases ua pa yog kwv yees li 400 lub sij hawm [citation ntxiv] uas ntawm butyl roj hmab, ua silicone pab rau kev kho mob daim ntaub ntawv nyob rau hauv uas muaj zog aeration yog qhov kev kawm. Conversely, silicone rubbers yuav siv tsis tau qhov twg gas-ceev cov ntsaws ruaj ruaj yog tsim nyog.
Roj hmab yuav tsim mus rau hauv roj hmab sheeting, qhov twg nws muaj lwm yam khoom, xws li ua FDA raws txoj cai. Qhov no ncua lub siv silicone sheeting rau industries uas demand kev tu cev, piv txwv li, cov zaub mov thiab dej haus thiab kws.
