ʻO ka mea maka mua no ka lāʻau silikika ʻāʻī -ākaʻina ʻo ia ka lāʻau silicone, he polysiloxane (Si-O chain structure). Hoʻohana ʻia ia ma ka hoʻohui ʻana i ka silica (silicon dioxide), kahi crosslinker, catalyst, a me nā mea kōkua ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ʻo Silicone rubber i ʻelua mau ʻāpana e pili ana i kona hoʻohana ʻana:
1. Lapa silicone paʻa: ʻO ka maʻamau he 20-80 Shore A. He vulcanized i nā wela kiʻekiʻe a kūpono ia no ka hana ʻana i nā sila kihi ʻākau, gaskets, a me nā huahana ʻē aʻe.
2. ʻO ka wai silicone rubber (LSR): Hāʻawi maikaʻi loa i ka hoʻoheheʻe ʻana a hoʻohana ʻia no ka hoʻoheheʻe ʻia ʻana o nā ʻāpana kihi ʻākau -pilikia. ʻO kona paʻakikī mai ka 5-70 Shore A.
Nā Hana Hoʻohui Nui:
- Silica: Hoʻonui i ka pale ʻana i ka waimaka a me ka ikaika mechanical;
- Platinum catalyst: Hoʻohana ʻia no ka -mea hoʻomāinoino ʻole o ka lāʻau lapaʻau-grade silicone;
- Masterbatch: Hoʻoponopono i ka waihoʻoluʻu akā pono e hoʻokō i nā kūlana FDA a i ʻole RoHS.
