1. Rubber Natural (NR)
Nā ʻano hana
Elasticity: ʻO ka lōʻihi o ka tensile a hiki i ka 1000%, me ke kūpaʻa maikaʻi loa (rebound resilience > 70%).
Ikaika Mechanical: Aia ka ikaika tensile mai ka 20–30 MPa, ke ku'e waimaka ma 50–60 kN/m.
Kaulana Mahana: -5 degere a 80 degere (palena wela lawelawe).
Palekana Kemika: Hiki i ka aila, ka ozone, a me ka waika ikaika.

ʻO nā sila no nā ʻenekini kaʻa, nā hoses wahie, a me nā ʻeke i nā mea hana petrochemical.
3. ʻO ka Rubber Silicone (VMQ)
Nā ʻano hana
Na wela wela: -60 degere a 250 degere (lawelawe mau), me ka thermal stability a hiki i 300 degere.
Biocompatibility: Ua hōʻoia ʻia ʻo USP Class VI no nā noi lapaʻau.
Nā palena: Haʻahaʻa waimaka ikaika (<10 kN/m) and poor oil resistance.
Nā noi maʻamau
ʻO nā catheters lāʻau lapaʻau, nā sila aerospace, a me nā ʻeke wela kiʻekiʻe i ka hana semiconductor.
4. Ka Lapa Chloroprene (CR)
Nā ʻano hana
Kūleʻa i ka lewa: Ozone resistance class A (ASTM D1149), UV stability >5 makahiki ma waho.
Kaulana Mahana: -30°C to 100°C, with flame-retardant properties (oxygen index >38).
Ikaika Mechanical: Ka ikaika uʻi 25–35 MPa, ke kū i ka waimaka 30–40 kN/m.
Nā noi maʻamau
Uea a me uwea insulation, uhi hale, a me ke ahi liner paipu.
5. Fluoroelastomer (FKM)
Nā ʻano hana
Palekana Kemika: Kū'ē i ka H₂SO₄ (98%), NaOH (50%), a me nā wahie lele.
Kaulana Mahana: -20 degere a 260 degere, me ka paʻa wā pōkole a hiki i 300 degere.
Na Waiwai Mechanical: Ka ikaika tensile 15–20 MPa, hoʻonohonoho hoʻoemi<20% at 200°C for 70h.
