The EPDM cover compound of this hose has been specifically formulated and certified to meet the UL94 V-0 flame retardant rating - the highest vertical burn classification, requiring that the material self-extinguishes within 10 seconds after each flame application with no dripping or flaming particles:

• Test method: UL94 vertical burn test per ASTM D3801. Specimen dimensions: 127mm × 12.7mm × hose wall thickness. Five specimens tested in each conditioned and aged state.
• Flame retardant mechanism: The compound incorporates a halogen-free phosphorus-nitrogen synergistic flame retardant system. Upon exposure to flame, the system forms a stable intumescent char layer that insulates the underlying polymer from heat and oxygen, simultaneously releasing non-combustible gases (N₂, CO₂) that dilute the flame zone.

 

While black is the standard color for most industrial applications, this hose series offers extensive color customization capabilities that serve both functional and aesthetic purposes:

• Standard colors: Red, yellow, and blue are available from stock with no minimum order quantity. These colors are commonly used for hot/cold line identification (red = hot supply, blue = cold return) or safety color coding per ISO 20560.
• Custom colors: Green, orange, white, gray, and other RAL colors available with minimum order of 300m per color. Custom color matching to customer-provided Pantone or RAL samples available with 2-week lead time.
• Color stability: All pigments are UV-stable and rated for outdoor exposure >5 years without significant fading (ΔE < 3.0 per CIE L*a*b* measurement after 2,500 hours QUV acceleration testing).

 

The EPDM compound provides excellent dielectric properties, making this hose suitable for applications near high-voltage equipment or where electrical isolation of the fluid path is required:

The non-conductive nature of the EPDM cover also eliminates the risk of galvanic corrosion between the hose and metallic fittings or adjacent conductive structures.

 

The EPDM inner tube can be cured using either sulfur-based or peroxide systems, each offering distinct advantages:

• Sulfur curing: Lower cost, faster cure speed, excellent fatigue resistance. Preferred for general-purpose cooling applications where the hose experiences frequent flexing or vibration. Slight risk of sulfur migration in ultra-pure water systems.
• Peroxide curing: Superior thermal stability (continuous use to +125°C), minimal ion extraction (<0.3 μS/m), better compression set. Specified for high-temperature steam applications, semiconductor-grade DI water systems, and applications requiring the lowest possible ionic contamination.
