Food Grade Wear-Resistant Anti-Static Powder Hose

This is a safety-type hose specially designed for the food and pharmaceutical industries, applied to the pneumatic conveying of highly abrasive dry powder and granular materials. It meets three core requirements simultaneously: food contact safety, high wear resistance, and static conduction/anti-static (explosion-proof) performance.

1. Core Material & Structure

The mainstream type is a food-grade polyether polyurethane (PU) hose reinforced with conductive steel wire:

• Hose Wall: Food-grade polyether PU (hydrolysis-resistant, mildew-proof, FDA/EU certified)

• Reinforcement Layer: Copper-plated / stainless steel spiral steel wire (for structural support, static conduction and electrostatic grounding discharge)

• Wall Thickness: 0.9–1.5mm (heavy-duty wear-resistant type)

• Anti-static Performance:Conductive modified hose wall; Surface resistance ≤ 10⁹ ΩGrounded steel wire quickly dissipates static electricity, complying with ATEX hazardous area requirements.

2. Key Performance (Food Grade + Wear Resistance + Anti-Static)

Food Grade Compliance

Compliant with FDA 21CFR 177.2600, EU Regulation 10/2011 and EC 1935/2004.Phthalate-free, odorless, microbial-resistant, and CIP cleanable.

Superior Wear Resistance

Polyether PU features 8–10 times higher abrasion resistance than ordinary PVC.Suitable for highly abrasive dry materials: flour, starch, sugar, milk powder, coffee powder, grains, feed, etc.

Anti-Static & Explosion-Proof

Stable surface resistance: 10⁶–10⁹ Ω, effectively preventing dust explosion risks.Applicable to Zone 20/21 dust explosive hazardous areas.

Temperature & Pressure Resistance

Operating temperature: -40°C ~ +90°C (125°C short-term peak)Vacuum resistant, positive pressure resistant, flexible and easy to bend.

3. Typical Application Scenarios

• Food Industry: Pneumatic conveying of flour, starch, sugar, milk powder and coffee powder

• Pharmaceutical Industry: Flexible connection for medicinal powder, granules, tablet presses and mixers

• Packaging & Filling: Dosing feeding, vacuum feeding and packaging machine hoses

• Explosion-Proof Working Conditions: Conveying systems with high-flow dust and easy static accumulation

4. Selection Guidelines

• Material: Prioritize food-grade polyether PU (abrasion-resistant & hydrolysis-resistant)

• Anti-static: Confirm surface resistance ≤ 10⁹ Ω with groundable steel wire

• Certification: Mandatory FDA, EU 10/2011 and China GB 4806 certification

• Wall Thickness: 1.4–1.5mm for heavy abrasion conditions; 0.9–1.0mm for standard working conditions
