Commonly referred to as the foam packaging, mainly refers to the epp material or EPS raw material through the mold through the hot processing, the production of packaging products commonly known as "foam".

Polystyrene is an ideal packing material, which can be processed into various shapes and thickness according to the need of forming process.

In the case of high load, the material can achieve cushioning and shock absorption by deformation, energy absorption and decomposing energy, and it has the function of heat preservation and insulation.

EPS packaging products are generally white, according to the requirements can produce color.

[main use characteristics]

1. Light weight.

The partial space of EPS packaging products is replaced by gas, and there are 3 to 6 million independent sealed bubbles in each cubic decimeter volume.

So it's a couple of times larger than plastic.

2. Ability to absorb shock load.

EPS packaging products under impact load, the gas bubble through stagnation and compression, make foreign energy is consumed, dissipation, bubble body with smaller negative acceleration, gradually ending impact load, thus has good shockproof effect.

3. Good insulation performance.

Thermal conductivity of pure EPS thermal conductivity (108 CAL/m.h. ℃) and air thermal conductivity (90 CAL/m.h. ℃ or so) of the weighted average.

4. Good sound insulation performance.

The sound insulation of EPS is mainly through two channels. One is to absorb the energy of sound waves and reduce reflection and transmission.

The second is to eliminate resonance and reduce noise.

5. Anti-aging and corrosion resistance.

In addition to long exposure to high energy radiation, the product has no obvious aging phenomenon.

Can tolerate many chemical substances, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc.

6. Anti-static performance.

Since EPS products have low electrical conductivity, it is easy to generate their own electrification in the friction, which will not affect the general user products.

For high-precision electronic products, especially modern electronics large-scale integrated block structure components, anti-static EPS products should be used.
