Designed for food processing pipelines, beverage filling equipment, commercial kitchen machinery, hot water & steam transmission pipelines. It combines excellent thermal insulation, anti-scald performance, shock absorption, waterproof and anti-condensation functions, ideal insulation sleeve for hot medium conveying pipelines in food workshops.
Core Advantages
-
Food-Grade Hygienic Safety
Platinum curing process, odorless and tasteless. No substance migration under high temperature steam. Will not absorb or transfer food flavor, safe for direct contact with drinking water, dairy, juice, edible oil, syrup. Suitable for repeated steam CIP cleaning and disinfection.
-
Excellent Heat Insulation & Anti-Scald
Uniform closed-cell microporous structure, thermal conductivity ≤0.035W/(m·K). Effectively block heat outward transmission, reduce pipeline surface temperature, prevent operator scald accidents. Reduce heat loss of hot fluid pipelines, save production energy consumption.
Working temperature: -60℃ ~ 200℃; instantaneous peak temperature up to 230℃. Keep flexible after long-term heating without hardening, cracking or decomposition.
-
Low Water Absorption, Anti-Mildew & Easy Cleaning
Water absorption rate ≤0.5%. Dense closed-cell structure resists water, oil and weak acid penetration. Not easy to breed mold and bacteria in high humidity food workshop environment. Surface smooth, convenient for wiping and regular sanitation.
-
High Resilience, Shock Absorption & Noise Reduction
Low compression set, stable rebound performance after long-term extrusion. Absorb pipeline vibration and flow resonance noise, reduce friction wear between pipelines and equipment.
-
Optional Flame Retardant Property
Custom halogen-free UL94 V-0 flame retardant formula available. Self-extinguishing after leaving fire source, low smoke, no molten dripping, improve fire safety of food processing workshops.
-
Weather Resistance & Long Service Life
Anti-ultraviolet, anti-ozone aging. No yellowing, embrittlement under long-term indoor high humidity environment, stable performance for many years.
-
Flexible Customization & Convenient Installation
Custom ID, OD, wall thickness, length, color. Soft tube body, arbitrary cutting and bending, adapt to complex bent pipeline layout. Tightly sleeved on stainless steel pipelines without shedding foam debris.
-
Chemical Inertness
No chemical reaction with stainless steel, plastic, food liquid medium, no corrosion to matched equipment.
Application Scope
- Beverage & dairy production lines: Thermal insulation casing for milk, juice, syrup, hot beverage delivery pipelines
- Commercial catering equipment: Coffee machines, steam ovens, milk tea equipment, hot water pipeline anti-scald insulation
- Food sterilization machinery: Steam circulation pipeline heat preservation sleeve
- Water purification & hot drinking equipment: Constant temperature insulation for hot water delivery pipes
- Food processing factory: Anti-condensation insulation for constant temperature conveying pipelines
Quality Control
All raw materials pass food migration test before production. One-step extrusion foaming ensures uniform pore and consistent wall thickness. Each batch undergoes high-low temperature cycle test, insulation performance test, microbial anti-mildew test, food safety migration inspection.
Usage Notes
- Select proper inner diameter according to pipeline outer diameter to achieve close fit and optimal heat preservation effect.
- Avoid violent stretching during installation to prevent damage to closed-cell structure.
- Avoid long-term continuous contact with strong acid, strong alkali concentrated cleaning agents.
- Store in dry and ventilated place, away from open fire and high temperature heat sources.
- Not recommended for continuous use exceeding the rated temperature range.
