Guia de seleção de reforço

– Polyester / Aramida / Nomex

Introduction

Há tecido de poliéster nas camadas intermediárias das mangueiras de silicone. O tecido da mangueira de silicone pode atuar como um reforço para as mangueiras de silicone. o material do tecido é sempre poliéster. é sempre calandrado junto com borracha de mangueira de silicone.

Reinforcement is critical to resistência mecânica, resistência à pressão, e estabilidade dimensional. HOTOP provides guidance on material selection based on application needs.

Common Reinforcement Types

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

»Aramida– 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 (Aramida, Nomex)

»Faixa de 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

Aplicações Típicas

»Turbocharger hoses → Aramid

»EV cooling loops → Polyester

»Hydrogen fuel cell hoses → Nomex or Aramid

»High-temperature industrial hoses → Nomex

Conclusão

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