• UV-blocking ani banakisɛfagalanw.

Nafaw:

• A bɛ sulfur vulkanization (a bɛ kɛnɛya waati dɔgɔya ni 20–30%) ye.

• A bɛ masinw ka nafaw ɲɛ (Tensile strength +15–25%, elongation at break +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).

• Ɲɛgɛnw: lastikuw ni nɛgɛ sirili (a bɛ dɔ fara a bɔli fanga kan ni 30–40% ye).

2. Resin fenɔliki .

Bolo fɛnw:

• Polimɛri thermosetting ni crosslink density sanfɛ.

• Funteni kunbɛncogo: Aw bɛ to ka a kɛ fo ka se 180°C ma (a bɛ kɛ 250°C ye).

• 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 ye kɔgɔjida la).

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

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