| Characteristics |
|
EXPANDING when EPS particles through heating source (over 90℃), it let EPS particles siftened.Expanding agent let EPS particles expanded and the expandable times reach 40-80. The
advantages of our products are low expanding temperature, quick velocity, high expandable times,
and fewer streams. |
|
|
|
MELTING When heating EPS particles through heating source (over 110℃), the EPS particles
becoming melt and adhesive. Considering low expanding and forming temperature of our products,
the more stable and the easier for the Combining. |
|
|
|
| The package of the EPS |
|
The EPS products of our company are packaged 25 kilograms a bag with craft paper-woven and a
plastic bag underneath. |
|
|
|
The storage of the
EPS |
|
The EPS series products of our company need to be put on the place where it is cool and ventilated,
keep the storage temperature below 20℃ in order to minimize the lost of frothing agents from
escaping. The lower the temperature is, the better the quality is. The products should avoid rain, fog,
snow and lighting up from the sun, static electricity and flame. Once the package material of the
products is open, it should be used up as quickly as possible. Otherwise, the remaining EPS might
lose its function due to escaping of foaming agents. If the EPS is stored too long, the expandable
times might decrease. |
