Anti-Scald Custom OEM/ODM from Tengye In dairy processing lines, beverage filling equipment, bakery ovens, commercial catering steam pipelines and food sterilization machines, hot medium pipelines need reliable thermal insulation, anti-scald protection, while complying with strict food contact safety standards. Heat Insulation Food Grade Silicone Sponge Tube is a hygienic closed-cell foamed silicone casing specially developed for food industry thermal preservation scenarios. Adopting platinum-cured food-safe silicone raw material, the dense closed-cell honeycomb structure locks static air to form an efficient thermal barrier, integrating heat insulation, energy saving, anti-scald performance and food safety. Tengye produces this tubing in dust-free clean workshops, providing long-term stable thermal insulation protection for hot steam, hot water and edible fluid conveying pipelines in food and catering industries.
Platinum Food-Grade Raw Material & Thermal-Optimized Closed-Cell Foaming Technology
Our heat insulation food grade silicone sponge tube adopts high-purity platinum vulcanized silicone without plasticizer, heavy metal and volatile peculiar smell. All extrusion and foaming processes are completed in dust-free food-grade production workshops, one-step continuous vulcanization forming uniform fine closed-cell pores inside the tube wall. Smooth inner and outer surfaces avoid residue of release agent, preventing secondary pollution to steam, fruit juice, dairy products and edible oil. Foaming density can be adjusted to optimize thermal conductivity, balancing soft wrapping performance and heat insulation efficiency. The product operates stably within -60℃ ~ 230℃, maintains stable elasticity after repeated steam sterilization, CIP cycle cleaning and cold-hot alternating cycles, no hardening, shrinkage or harmful substance precipitation. It features excellent resistance to edible grease, fruit acid, vinegar and food alkaline detergents. All products comply with FDA 21 CFR 177.2600, EU LFGB, RoHS 2.0 and REACH. Complete SGS food migration test reports can be supplied for inspection and export customs clearance.
Core Performance Advantages
Focused on the dual demands of food safety & efficient heat preservation, this tubing solves the defects of ordinary industrial insulation sleeves that cannot contact food, poor heat insulation and hardening after high temperature:
-
✅ Food Contact Safety, Non-Toxic & Odorless Platinum curing formula, zero harmful precipitation, safe for indirect contact with food, dairy, beverage and hot steam, meets international food hygiene standards.
-
✅ Excellent Thermal Insulation & Anti-Scald, Energy Saving Closed-cell structure forms stable air thermal barrier, effectively reduce pipeline surface temperature, prevent staff scald accidents, reduce medium heat loss and lower equipment operating energy consumption. Thermal conductivity reaches 0.05~0.08 W/m·K.
-
✅ Resist Repeated High-Temperature Sterilization Adapt to boiling disinfection, autoclave and online cycle cleaning; no odor precipitation, no deformation after long-term frequent sterilization cycles.
-
✅ Oil, Acid & Alkali Resistant, Easy Sanitation Low oil-absorption smooth surface, not easy to adhere food residues, simply flush and wipe clean, inhibit mildew growth in humid food workshop environment.
-
✅ Low Compression Set & Flexible Bending Compression set ≤5%, long-term wrapping without permanent deformation; soft texture can bend freely to fit complex pipeline layout of food machinery.
-
✅ Outstanding Weather & Aging Resistance Resist ultraviolet, ozone and temperature alternating aging, long service life in continuous production environment of food factories.

Installation & Storage Precautions
-
Clean pipeline surface thoroughly before sleeving, remove dust and grease to avoid contamination;
-
Avoid excessive stretching and sharp scratch during installation to prevent damage to internal closed-cell structure and reduce insulation effect;
-
Do not store together with corrosive chemicals; keep in cool, dry and dust-free warehouse, avoid long-term direct sunlight;
-
Select appropriate wall thickness and density according to medium temperature and daily disinfection frequency to achieve optimal heat preservation effect.
