Guida alla selezione delle armature

– Polyester / Aramide / Nomex

Introduzione

C'è un tessuto in poliestere negli strati intermedi dei tubi in silicone. Il tessuto del tubo in silicone può fungere da rinforzo per i tubi in silicone. il materiale del tessuto è sempre poliestere. è sempre calandrato insieme a gomma siliconica.

Reinforcement is critical to resistenza meccanica, resistenza alla pressione, e stabilità dimensionale. HOTOP provides guidance on material selection based on application needs.

Common Reinforcement Types

»Poliestere – Good flexibility, medium strength, general automotive and industrial use. Working temperature -50C to +180C.

»Aramide– High tensile strength, excellent thermal stability, for high-pressure or turbo applications, high-temperature working silicone hose option.Working temperature -50C to +280C.

»Nomex– High heat resistance, fire retardant, for extreme temperature or hydrogen

applications.Working temperature -50C to +300+C.

Material Selection Guidelines

»Pressure Requirements – Higher pressure → stronger fibers (Aramide, Nomex)

»Intervallo di temperatura – High temp → Nomex or Aramid

»Flexibility Needs – Tight bends → Polyester preferred

»Chemical Exposure – Ensure fiber compatibility with silicone and fluids

HOTOP Engineering Considerations

»Multi-ply reinforcement design for optimal pressure resistance

»Fiber orientation tuned for vibration and fatigue resistance

»Bonding to silicone compound carefully controlled

Applicazioni tipiche

»Turbocharger hoses → Aramid

»EV cooling loops → Polyester

»Hydrogen fuel cell hoses → Nomex or Aramid

»High-temperature industrial hoses → Nomex

Conclusione

Reinforcement selection is essential for silicone hose performance. HOTOP engineers design application-specific reinforcement to ensure durability, flessibilità, and reliability.
