Comparison Of EPS And XPS

COMPARISON OF EPS AND XPS

XPS raw material is a polystyrene based material used in isolation such as EPS. In our country, the difference between these two materials is emphasized due to the fact that users are misdirected without comparing prices and features sufficiently while making preference between them. The heat insulation properties of the typesof types of EPS and XPS with same density are very close. In contrast, EPS with same intensity is more cost effective than XPS. In addition, where materials with lower density can be selected, XPS (because it can not be produced below a certain density) can not be used. In this case, with the use of thicker EPS with lower density, both the necessary heat insulation is ensured and great cost advantages are obtained. 

Thermal conductivity: After contact of raw material with air in XPS foamed with EPS and CO2, the thermal conductivity increases in small quantity and exceeds the thermal conductivity of the air.

Lower heat conductivity can be achieved by using HFCKVV or HFKW gases. Thus, the difference between EPS and XPS approaches each other. In addition, the ecological characteristics of the various gases used in XPS production have great differences. Here are two ecological effects: ozone-depleting potential and greenhouse effect. C02 is the main gasimposing greenhouse effect. The relative value of CO2 is 1. According to this table, for example, in the eventthat FCKVV12 gas is used in XPS production, this gas has a greenhouse effect of 7300 times higher than CO2. Only Pentan gas is used in EPS production and this gas does not cause damage to the ozone layer and does not create greenhouse effect. You can use the tables below to compare the properties of these two products. 

Note: The initial value is determined for thicknesses less than 50 mm, the second value is determined for thicknesses greater than 50 mm.
