Thermal Insulation Foam Sheet for Refrigerator & Cooling Equipment

Premium Closed Cell Rubber Foam Insulation Sheet for Refrigeration & HVAC Systems
Our insulation sheet is manufactured from high-quality NBR/PVC blended rubber foam with a uniform, dense closed-cell structure. It is a professional thermal insulation and sound absorption material widely used for refrigerator liner insulation, freezer thermal protection, cold storage wall and floor laying, as well as commercial HVAC equipment insulation. With stable physical properties and outstanding environmental adaptability, it is a cost-effective solution for global refrigeration supporting and engineering projects.

Superior Thermal Insulation & Energy Saving Performance
The compact closed-cell structure effectively isolates air convection and heat radiation, greatly reducing external heat penetration and internal cold loss. It stabilizes the internal temperature of refrigeration equipment and cold storage space, lowers the long-term operating load of compressors and air conditioning units, and delivers consistent energy-saving effects for continuous cooling operation.

Excellent Waterproof & Anti-Condensation Effect
The foam sheet features ultra-low water absorption and reliable vapor barrier performance. It can completely block moist air penetration, avoid surface sweating, water droplet accumulation and mold growth caused by temperature difference. It keeps refrigeration equipment interiors and enclosed cooling spaces dry, preventing corrosion and equipment failure in high-humidity working environments.

Flame Retardant & Safe Eco-Friendly Material
This thermal insulation sheet adopts upgraded flame-retardant formula with self-extinguishing and non-propagation characteristics, fully meeting international HVAC and refrigeration fire safety standards. The material is non-toxic, odorless and free of harmful volatile substances, safe for indoor commercial use, enclosed engineering spaces and household refrigeration equipment.

Sound Absorption & Noise Reduction
The dense porous closed-cell structure can effectively absorb operating noise from compressors, fans and cooling units. It reduces equipment resonance and airflow noise, improving the working environment comfort for commercial cold rooms, display cabinets and HVAC systems.

Flexible Cutting & Easy Construction
The insulation foam sheet is lightweight, soft and tough, not easy to crack or break. It can be freely cut, bent and pasted according to equipment size and construction needs. No complex tools or professional processes are required, greatly improving on-site laying efficiency and shortening construction cycles.

Strong Durability & Wide Application
Featuring excellent aging resistance, oxidation resistance and compression resistance, the sheet will not harden, shrink or deform after long-term low-temperature and high-humidity use. It is widely applicable for household refrigerators, freezers, supermarket display showcases, cold storage warehouses, central air conditioning units and industrial cooling equipment, suitable for global bulk wholesale and engineering supporting.
