3. Application:
This Flame retardant grade EPS can be used as building-materials, materials for heat preservation, thermal insulation and for packing precision instruments
4. Storage:
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°C 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.
