Core Advantages of Rubber Foam Insulatiob Board
Superior Closed-Cell Thermal Insulation
The rubber foam insulation board adopts a dense closed-cell structure made of high-quality NBR-PVC composite materials. It owns ultra-low thermal conductivity, which can effectively lock temperature, reduce heat transfer and avoid cold and heat loss. It delivers stable heat preservation and cold insulation effect all year round, greatly cutting down energy consumption for buildings and pipelines.
Excellent Waterproof & Moisture Proof Performance
Thanks to its independent closed-cell design, the material features outstanding water vapor barrier capability. It can effectively block moisture penetration, prevent surface condensation, mildew and corrosion. It keeps stable physical performance even in humid, rainy and high-temperature environments, perfectly adapting to complex indoor and outdoor construction conditions.
Fire Retardant & Safety Environmental Protection
The insulation board is processed with high-standard flame retardant formula, with good self-extinguishing and fire-resistant ability. It can inhibit the spread of flames and improve building safety. Meanwhile, the product is non-toxic, odorless, eco-friendly and harmless to human body and air quality, meeting international environmental protection and construction safety standards.
Sound Absorption & Noise Reduction Effect
With soft porous internal structure, the rubber foam board has remarkable sound insulation and sound absorption performance. It can effectively isolate and weaken airflow noise, equipment operation noise and environmental noise. It is an ideal material for noise reduction in air conditioning ducts, factory workshops, commercial buildings and residential walls.
Flexible Material & Easy Installation
The product is lightweight, flexible and tough, not easy to crack or deform. It can be freely cut, bent and fitted for pipes, ducts, walls and roofs of different shapes. No complex construction tools or auxiliary materials are needed, saving construction time and labor cost with high fitting integrity.
Aging Resistance & Long Service Life
Made of high-density rubber-plastic polymer raw materials, the insulation board resists aging, oxidation and high and low temperature erosion. It will not shrink or collapse after long-term use, maintaining stable thermal insulation and sound insulation performance for years. It features strong weather resistance and ultra-long service life, cost-effective for long-term engineering use.
