Selectiegids voor wapening

– Polyester / Aramide / Nomex

Invoering

In de middelste lagen siliconenslangen zit polyesterweefsel. Het siliconenslangweefsel kan dienen als versteviging van de siliconenslangen. het materiaal van de stof is altijd polyester. het wordt altijd samen gekalanderd met siliconenslangrubber.

Reinforcement is critical to mechanische sterkte, pressure endurance, en maatvastheid. HOTOP provides guidance on material selection based on application needs.

Common Reinforcement Types

»Polyester – 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)

»Temperatuurbereik – 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

Typische toepassingen

»Turbocharger hoses → Aramid

»EV cooling loops → Polyester

»Hydrogen fuel cell hoses → Nomex or Aramid

»High-temperature industrial hoses → Nomex

Conclusie

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