Claims (14)
1. Elastomerni članak koji sadrži najmanje jedan elastomer i čestice istaloženog kalcijevog karbonata, naznačen time što:
sferni ekvivalent veličine čestice navedenih čestica istaloženog kalcijevog karbonata manji je od 1.0 µm, pri čemu se sferni ekvivalent veličine čestice čestica istaloženog kalcijevog karbonata određuje pomoću sljedeće jednadžbe:
Sferni ekvivalent veličine čestice [µm] = 2.21 / BET [m2/g],
pri čemu se BET određuje kako je definirano u opisu;
istaloženi kalcijev karbonat ima prosječnu veličinu čestica (d50%) u rasponu od 0.8 µm do 1.2 µm; i navedeni elastomer izrađen je od čestica lateksa od najmanje jedne gume koja se prirodno pojavljuje okružena proteinskim anionima, pri čemu je navedeni lateks od prirodne gume disperzija cis-1.4-poliizoprena u vodi.
2. Elastomerni članak prema zahtjevu 1, naznačen time što je sferni ekvivalent veličine čestice navedenih čestica istaloženog kalcijevog karbonata manja od 500 nm.

(2) potapanje kalupa u gumenu lateks emulziju koja sadrži čestice kalcijevog karbonata, kako bi se formirao sloj zgrušanog gumenog lateksa koji sadrži čestice kalcijevog karbonata, na površini kalupa;
(3) sušenje koaguliranog gumenog lateksa kako bi se oblikovalo tijelo od elastomernog predmeta na kalupu; i
(4) uklanjanje tijela elastomernog članka iz kalupa, pri čemu
navedeni elastomerni članak sadrži najmanje jedan elastomer i čestice istaložeog kalcijevog karbonata,
sferni ekvivalent veličine čestice navedenih čestica istaloženog kalcijevog karbonata manji je od 1.0 µm, pri čemu se sferni ekvivalent veličine čestice čestica istaloženog kalcijevog karbonata određuje pomoću sljedeće jednadžbe:
Sferni ekvivalent veličine čestice [µm] = 2.21 / BET [m2/g],
pri čemu se BET određuje kako je definirano u opisu;
istaloženi kalcijev karbonat ima prosječnu veličinu čestica (d50%) u rasponu od 0.8 µm do 1.2 µm; i
