[R2SiO]n
Chemistry실리콘 is specified as [R2SiO]n. Density band ~1.1–1.5 g/cm³.
What holds 실리콘 together is not the nickname. Formula [R2SiO]n, density ~1.1–1.5 g/cm³.
Meters are atlas-relative. Grades are the SKUs buyers write.
단계
Microstructure
OrderProcessing sets grain, crystallinity or fibre orientation — the reason two lots of 실리콘 can test differently.
Interfaces
SurfacesCoatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.
Defects
FlawsInclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.
Grades
Variants실리콘 is a family. Grade names below are the ones buyers actually write on RFQs.
Ageing
TimeMoisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.

결합
Primary bonding
실리콘 holds together by covalent chain chemistry.
Secondary forces
Hydrogen bonds, van der Waals stacks or grain-boundary cohesion set toughness and moisture uptake.
Composites & fills
Fillers, fibres, plasticisers or aggregates are part of the real product, not impurities.
Environment film
Oxides, chars, sizings or paints are the layer the world actually meets.
Change the grade, the coating or the moisture and you have a different material with the same English name.
