1. Ukubuka Konke Komkhiqizo
I-Decamethylcyclopentasiloxane (D5, CAS 541-02-6) iyi-cyclic siloxane engenambala, engenaphunga, futhi eguquguqukayo kancane esetshenziswa kabanzi njengoketshezi oluyisisekelo kanye nesithwali esiguquguqukayo emiklamweni yezimonyo nokunakekelwa komuntu siqu. Ngefomula yamangqamuzana C₁₀H₃₀O₅Si₅ kanye nesisindo samangqamuzana esingu-370.77, i-D5 ibonakala ngokungezwani okuncane kwendawo (cishe 18.8 mN/m ku-25°C), i-viscosity ephansi (2.4 mm²/s), kanye nokuhwamuka okusheshayo okungashiyi insalela esikhumbeni noma ezinweleni. Lo mkhiqizo awunamafutha, awucishi, futhi unikeza izakhiwo ezinhle kakhulu zokusabalalisa nokugcoba.
Njengomhlinzeki ohamba phambili we-decamethylcyclopentasiloxane kanye nomkhiqizi we-D5 silicone, i-Xinchem inikeza i-D5 yekhwalithi ephezulu (≥99%) yezimonyo esekelwa isitifiketi se-ISO9001 nokuhambisana ne-REACH. Sisekela kokubili ukuhlanganiswa kwangokwezifiso kanye nokuhlinzekwa ngezinto eziningi/okuthengiswa ngobuningi kubathengi bomhlaba wonke kwezimonyo, ukunakekelwa komuntu siqu, imithi, kanye nezicelo zezimboni.
