Silicone yambura kuphika raba ndiyo yikukhozga vinthu vya labala vyakupangika. Katundu wa labala wakupangika kufuma ku mitundu yakupambanapambana ya labala wambura kupangika .
chomene. Vinthu ivyo vikukhumbikwa kuti viŵe vyambura kupangika vikupambana na mitundu yakupambanapambana ya labala wakupangika.Katundu wakwamba wa labala wambura kuphika wakuthemba pa vimanyikwiro vitatu: unandi wa molar, vinyl ivyo vili mu vinyl na vinthu vyakusinthasintha.
Pa nyengo ya kupanga, labala wakupangika na maselo ghakupambanapambana na vinyl kanandi wakugwiriskirika nchito pamoza mu chigaŵa chinyake. Para chinthu ichi chikukhora chomene, ndikuti vinyl yikukhumbikwa chomene pa labala wambura kupangika. Nkhani yakusinthasintha yikukhumbikwa kuti yiŵe yapakatikati (1% mpaka 2%). Usange vinthu ivyo vikusinthasintha vikukwera chomene, chinthu cha raba chizamuŵa chakumatira ndipo ntchito yake yizamuchepa, apo usange vinthu ivyo vikusinthasintha ni vichoko chomene, chiŵenge chakusuzga kuti chinthu cha raba chileke kuŵa na “ufa wa absorb”.
Generally speaking, the higher the molar mass, the better the physical and mechanical properties of the vulcanized rubber, but its processability and fluidity will decline, and the speed of "powder intake" (filler mixing into raw rubber) will slow down. When processing molded compound rubber, raw rubber with a high molar mass (>600,000) kanandi ŵakusankhika. Ndipouli, para ŵakupanga vinthu vyakufumiskika, kuti ŵatuŵiske kusintha kwa maji, unandi wa molar ukwenera kuŵa wakucepa pachoko. Kukura kwa vinyl kuli na nkhongono yikuru pa nchito yakukwana ya labala wakusazgikana. Kugwira ntchito na kusintha kwa labala wakupangika na vinyl ivyo vili na 0.1% kufika pa 0.2% ndivyo viwemi chomene.
