Thermal Insulation Food Grade Foam Pipe

Food-Grade Silicone Raw Material & Clean Foaming Extrusion Process

Core Performance Advantages for Food Industry

• Full Food Safety Compliance：Pure food-grade silicone formula, non-toxic, tasteless, no heavy metal precipitation, safe direct contact with water, milk, fruit juice, edible oil and all hot and cold food materials, in line with FDA and LFGB international food certification standards.
• Excellent Heat Insulation & Anti-Scald：Uniform closed-cell porous structure forms stable air heat insulation layer, effectively isolate high temperature inside the pipe, prevent operators from scalding when touching hot steam and hot liquid pipelines, reduce heat loss and energy consumption of equipment.
• High & Low Temperature Resistant & Sterilizable：Long-term stable use from -60℃ low temperature freezing to 230℃ high temperature steam, support high temperature boiling, autoclave and CIP online cleaning and disinfection, no deformation or odor after repeated sterilization cycles.
• Oil & Acid-Alkali Resistance：Not easy to absorb grease, resist corrosion of edible oil, vinegar, fruit acid and food alkaline detergent, easy to wipe and clean, no mildew and residual stain after long-term use.
• Low Compression Set & Flexible Bending：Good rebound performance, compression set ≤5%, no permanent deformation after long-term clamping and extrusion; soft texture, can be bent arbitrarily to adapt to complex layout of food equipment pipelines.
• Mildew & Aging Resistant：Not easy to breed mold in humid kitchen and food workshop environment, anti-ultraviolet and hot and cold cycle aging, long service life, replace less frequently.
• Smooth Surface & Easy Sanitation Management：Smooth inner and outer tube wall, not easy to adhere food residue, convenient daily cleaning and disinfection, effectively reduce bacterial breeding risks in food production lines.

Main Application Scenarios

• Beverage & Dairy Production Equipment：Heat insulation and anti-scald wrapping for milk pipelines, fruit juice delivery pipes, beverage filling machine steam pipes, yogurt fermentation equipment pipelines.
• Bakery & Food Processing Machinery：Thermal insulation protection for oven steam pipes, baking equipment hot oil pipelines, noodle cooking hot water pipes, food sterilization equipment pipelines.
• Catering Kitchen Equipment：Anti-scald insulation sleeves for coffee machine hot water pipes, steam oven pipelines, commercial water boiler hot liquid pipelines, buffet heating equipment pipes.
• Cold Storage & Fresh-Keeping Equipment：Heat preservation pipeline sleeves for cold drink equipment, refrigerated liquid conveying pipes, low-temperature food circulation pipelines to avoid condensation and frost.
• Food Packaging & Small Household Food Appliances：Safe heat insulation tubes for milk makers, fruit juicers, commercial food blenders and food filling small equipment.

Precautions for Use

• Before installation, thoroughly clean the surface of the pipeline and the inner wall of the silicone tube, wipe off dust, oil and impurities to avoid contaminating food materials during use.
• Control the stretching amplitude during installation, avoid excessive pulling to prevent tube wall pore damage and affect heat insulation effect; avoid sharp metal scratches piercing the tube body.
• Control the compression ratio reasonably during assembly, generally 25%-40%, long-term over-compression will cause permanent deformation and lose heat preservation buffering performance.
• Clean the tube regularly with food alkaline detergent and hot water after long-term contact with edible oil to prevent grease residue and mildew growth.
• Store in cool, dry and dust-free clean warehouse before installation, keep away from industrial corrosive chemicals and strong sunlight to avoid premature aging.
• Select the corresponding wall thickness and density grade according to the actual medium temperature, food type and disinfection frequency to match food production safety standards.

Strict Quality Control System

• Raw Material Inspection 100% test all food-grade silicone raw materials, strictly detect heavy metal precipitation, volatile substances and food contact safety indicators, unqualified raw materials are prohibited from production.
• In-Process Monitoring All foaming and extrusion processes are completed in dust-free workshop, real-time control foaming ratio, extrusion temperature and dimensional tolerance to ensure uniform tube wall pores, smooth surface and no impurity defects.
• Finished Product Comprehensive Testing Conduct food safety precipitation test, high-low temperature cycle test, steam sterilization aging test, oil resistance and compression rebound test for each batch, provide complete food certification and test reports.
