1. Anti-aging performance

EPS foam is resistant to rot, but not for a long time in the sun insolates, otherwise, a few weeks later, degradation by surface gradually yellow, but only have an effect on the surface, under normal circumstances for large parts of the foam have little effect, may affect the performance of the sheet. Suggest foam parts not exposed to direct sunlight for weeks to store or use in exposed places, especially in the sunlight, rain and wind, under the comprehensive effect of the surface of the bubble will be further erosion. Parts of the density is higher, the stronger ability to resist erosion.

The diffusion of water vapour will not change the performance of the foam, the continuous can be used even if the maximum allowable temperature 85 ℃, also is such. Water affects only the coefficient of thermal conductivity, and only in the bubble water influence. Once the bubble is dry, then restore the original heat insulation performance.

EPS parts can at low temperature without time limit to use. Formation of polystyrene foam structure is the amorphous plastic, even in a fundamental structural change - 180 ℃ which doesn't happen.

2. The ecological performance

In the process of processing or storage of EPS, will release a small amount of pentane. When using heating wire cutting EPS board, will release a small amount of pentane, pentane is a volatile liquid, half-life is only 2 ~ 3 days. Release the pentane in the process of production will be affected by air temperature and radiation in the atmosphere, under the photochemical reaction is converted into carbon dioxide and water, so the atmosphere of pentane content only 2 x 10-10, therefore does not affect the environment.

EPS particles, only 0.1% of residual styrene monomer content, EPS processing molding process will release a small amount of styrene, but will not cause harm to the environment. Styrene half-life is short, so fast; even around the production equipment is less than the emissions of styrene.

During the life of the EPS will not cause harm to the health of people. In a similar to the actual use of test site, with a precision up to 0.01 mg/m3 of indoor air testing instruments for 16 with different method, the samples were measured on the wall, the results did not detect styrene.

Experiments show that EPS even if be used more than 30 years, its performance also won't have any change. And EPS does not contain microbes, mold, bacteria, fungi such as needed for the survival of nutrient material, not loose embrittlement, nor to decay, more will not dissolve in water, also won't escape of water-soluble substances, subjected to ground water pollution, garbage can be disposed and family together soil buried or burned.
