• UV-blocking ani banakisɛfagalanw.

Nafaw:

• A bɛ kisɛkisɛ vulkanizeli teliya (a bɛ kɛnɛya waati dɔgɔya ni 20–30%).

• A bɛ masinko nafaw ɲɛ (sɛgɛsɛgɛli fanga +15–25%, janya kari waati +10–15%).

• FDA sɔnna dumuni-ɲini-walew ma (21 CFR 172.480).

• Sigida lakanani (min tɛ baga ye, a bɛ se ka segin a cogo kɔrɔ la).

Aplikasi:

• Tigɛw: Taye suw (min bɛ na ni nɛgɛ ye) (a bɛ kɛ sababu ye ka lastikuw ni nɛgɛw nɔrɔ ɲɔgɔn na).

• Sennasanbara : outsole compounds (a bɛ abrasion resistance, ASTM D5963: 50–80 mm3 bɔnɛ).

• Dɔgɔtɔrɔso: Opereli ganw (an ka banakisɛfagalanw lakanani, ASTM E2149).

• Nɛgɛw : Lastikuw ni nɛgɛ sirili (o bɛ dɔ fara a ɲɛkisɛ fanga kan ni 30–40%).

2. Résine Fenolique (Fɛnoliki Resin).

Bolo fɛnw:

• Polimɛri min bɛ thermosetting ni a ka crosslink density ka bon.

• Funteni kunbɛnni : Aw bɛ to ka a kɛ fo ka se 180°C ma (a bɛ kɛ 250°C waati ni waati).

• Kɔrɔbɔliba (modulu: 2–4 GPA) ani dimension stabilité.

• Asidiw, basiw ani furajiw bɛ se ka kɛ kemikaliya ye.

Nafaw:

• A bɛ jɔli barika bonya (a bɛ dɔ fara a gɛlɛya kan ni 10–20 Shore A ye).

• Flame Retardant (UL94 V-0 hakɛ min tɛ halogen faralenw ye).

• A musaka ka dɔgɔ ni a bɛ tali kɛ thermoplastiques spécialisés la.

• Furakɛcogo minnu bɛ se ka kɛ ka kɛɲɛ ni mɔgɔw sago ye (asidi-katalizi walima funteni-activé).

Aplikasi:

• Tiiriw: Kɛrɛfɛ kogow (a bɛ se ka tigɛ, ASTM D624).

• Industriw ka cɛsirilanw : fɛnw bɛ taa ni fɛnw ye minnu bɛ se ka kɛ sababu ye ka funteni caman sɔrɔ (misali la, siman jiriw).

• Friction materials: frein pads (a bɛ coefficient de friction kɛ 0,35–0,45 la 200°C jukɔrɔ).

• Foundry: Core Sand Binders (a bɛ gazi sɛnɛcogo dɔgɔya casting waati la).
