Structure: composite material
Material: NBR / PVC, aluminum foil
Specifications: 5mm thick, can be customized according to customer requirements
Fire rating: Class A
Environmental protection level: E1 level
Uses: sound insulation, heat insulation, shock absorption, flame retardant, etc.
对引擎盖的防护以吸热和隔热为主。 The hood insulation cotton protects the hood by absorbing heat and heat. Using glass fiber aluminum foil, the insulation effect is stronger than ordinary aluminum foil. It not only has the function of heat insulation, but also has the function of flame retardant, waterproof and dustproof. Insulated alumina fiber, anti-aging, longer life.
大优势： Six advantages:
防火等级：防火等级达A级。 1) Fire rating: A fire rating. GB8624-1997A级 Good fire performance, non-combustibility reaches GB8624-1997A隔音量大：最低隔音量达37dB 2) Large sound insulation: The minimum sound insulation is 37dB
环保防火：完全满足环保E1级:100%不含石棉，遇火无烟无毒，营造绿色健康生活空间。 3) Environmental protection and fire protection: fully meet the environmental protection E1 level: 100% non-asbestos, smoke-free and non-toxic in the event of fire, creating a green and healthy living space.
防爆裂：可防外物撞击后的爆裂，在潮湿环境可正常使用。 4) Explosion-proof crack: It can prevent the burst of foreign objects after impact, and can be used normally in humid environment.
止震性：止震、缓冲性强，多用于汽车引擎盖隔热，底盘隔音减震，设备隔热减震。 5) Shock absorption: shock absorption and cushioning are strong, mostly used for car hood insulation, chassis sound insulation and shock absorption, equipment heat insulation and shock absorption.
耐候耐久性：产品具有耐水性，耐热性，抗紫外线，不会因雨水温度变化引起降低性能或品质异常。 6) Weathering durability: The product has water resistance, heat resistance, and ultraviolet resistance, and will not reduce performance or quality abnormality due to rain temperature changes. 。 Anti-mildew, anti-bacteria, anti-insect, anti-termite .
Used for car hood insulation, engine insulation and noise reduction
Principle: Closed-cell foam structure, which consists of cavities, absorbs and refracts sound and weakens it. Reflect environmental protection and light weight at the same time, effectively blocking roads while driving
Surface, frictional sound caused by air resistance, etc .; the open-cell foam structure absorbs widely and efficiently
Sound waves in the frequency band, while greatly reducing sound wave reflections, and effectively suppressing the cockpit
The reverberation produced restores the sound quality of the sound.
Comes with self-adhesive on the back, using environmentally-friendly materials, strong adsorption, firm adhesion, and no deformation. (Friendly tip: wipe the installation position clean before pasting)
The surface aluminum foil is like a thick "raincoat", blocking the rainwater from the outside, preventing the rainwater from invading the insulation cotton and causing foaming and mildew, which prolongs the service life of the automobile engine.
Flame retardant test
NBR/PVC 阻燃棉，其特点就是阻燃，用打火机燃烧时，不会出现明火现象，不燃烧不助燃，碰到明火直接耗尽化为黑色粉末状，离开明火就熄灭。 Car cover insulation cotton uses NBR / PVC flame-retardant cotton, which is characterized by flame resistance. When burning with a lighter, no open flame phenomenon will occur. It will not burn and will not support combustion. When it encounters an open flame, it will be depleted into a black powder. It goes out.
What is the amount of sound insulation materials for a typical hatchback?
11 个平米（四门 2-3 平方米；底盘 3 平方米；后备箱 2 平方米， 引擎盖 1- 1.5平方米；四轮挡泥板2 平方米；顶棚 1-2 平方米）， 只能给算出个大概用量，很难计算准确，即便同一台车，用料也会不一样，若是汽车 隔音隔热材料留多一点，可以用来塞一些边缝，也不会浪费的哦~ The amount varies greatly depending on the size of the car body and the construction method and the degree of care of the rider. The general two-seater sedan is about 11 square meters (two doors 2-3 square meters; chassis 3 square meters; trunk 2 Square meters, hood 1-1.5 square meters; four-wheel fenders 2 square meters; ceiling 1-2 square meters), can only calculate the approximate amount, it is difficult to calculate accurately, even if the same car, the materials will be Not the same, if the car's sound insulation material is left a little more, it can be used to plug some side seams, and it will not be wasted ~
