PA11 Arkema BESNOP40TL
PA11 Arkema BESNOP40TL Resin
Material Introduction: PA11 Arkema BESNOP40TL is a polyamide‑11 resin with outstanding flexibility and impact‑resistance. It also delivers good chemical‑corrosion resistance, wear‑resistant self‑lubricating property, bio‑based eco‑friendly feature, low‑moisture‑absorption and excellent dimensional stability.
Main Applications
Automotive fuel / brake‑system components (core application): Multi‑layer fuel‑pipe barrier layers (compliant with China‑VI evaporative emission standard), brake hoses, pneumatic pipelines (DOT3/4 brake‑fluid resistance).
Flexible high‑pressure pipes: Industrial hydraulic hoses, compressed‑air tubes (pressure resistance ≥20 MPa).
Electronic cable sheaths: Robot cables, submarine cables (bending‑fatigue resistance＞5 million cycles).
Precision moving parts: UAV gears, ski bindings (low‑temperature impact‑resistance).
Food‑contact & medical parts: Compliant with FDA / EC 1935 standards, applied for milk‑pump valves, endoscope sleeves.
