Foam is no stranger to everyone. It is a common thermal insulation material and can also be used as packaging material. Zhengzhou Foam Factory believes that foam is widely used in life. What are the characteristics of foam packaging? Zhengzhou Foam Factory summarized a few points, let's take a look.
1. Lightweight. Zhengzhou Foam Factory introduces that part of the space of EPS packaging products is replaced by gas. Each cubic decimeter contains 3-6 million independent closed gas bubbles. It is therefore several times to several tens of times larger than plastic.
2. Capable of absorbing shock load. When the EPS packaging product is subjected to an impact load, the gas in the packaging foam of Zhengzhou Foam Factory stagnates and compresses, so that external energy is consumed and dissipated. The foam body gradually terminates the impact load with a small negative acceleration. Zhengzhou Foam Factory believes that it has Good shockproof effect.
3. Good insulation performance. Thermal conductivity is the weighted average of pure EPS thermal conductivity (108cal / mh ° C) and air thermal conductivity (about 90cal / mh ° C).
4. Good sound insulation performance. Zhengzhou Foam Factory introduces EPS product sound insulation mainly through two ways: one is to absorb sound wave energy, reduce reflection and transmission; the other is to eliminate resonance and reduce noise.
5. Anti-aging and corrosion performance. Except for prolonged exposure to high-energy radiation, the product has no obvious aging phenomenon. Zhengzhou Foam Factory believes that it can tolerate many chemical substances, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc.
6. Anti-static performance. Zhengzhou Foam Factory introduced that because EPS products have low electrical conductivity, they are prone to self-charging in friction, and will not affect general user products. For high-precision electronic products, especially large-scale integrated block structural elements of modern electrical appliances, antistatic EPS products should be used.
