Insulation Board EPS and XPS Performance Comparison
Expanded Polystyrene EPS is a white object from Expandable Polystyrene Beads containing a volatile liquid blowing agent is heated after forming an advance in the mold. It structural characteristics of fine obturator. XPS is use Expanded Polystyrene Resin as a raw material, through a special process of continuous extrusion foaming of rigid plates, internal independent closed cell structure, is a high-compression, non-absorbent, moisture-proof, airtight, lightweight, corrosion-resistant, long life, low thermal conductivity, excellent performance of environmentally friendly insulation material.
Excellent, long-lasting insulation properties:
XPS thermal conductivity is 0.028 w/mk, having high thermal resistance, low linear expansion characteristics. Its thermal conductivity is much lower than other insulation materials, such as: EPS board, Foam Polyurethane, Insulation Mortar, Cement Perlite. And because the material has a stable chemical and physical structure, thermal insulation properties of this material ensures durability and stability.
Superior resistance to water, moisture resistance:
XPS resistance to water, moisture is better than other insulation materials, XPS board has a compact closed-cell structure. Expanded Polystyrene molecular structure itself does not absorb water, positive and negative plates are no gaps. Therefore, low water absorption, excellent moisture and anti-permeability.
Corrosion, durability:
The general aging of rigid foam insulation material is easy to produce a few years later, subsequently lead to water absorption, resulting in performance degradation. And because XPS board has excellent anti-corrosion, anti-aging and insulation properties, at high water vapor pressure, can still maintain quality, make the useful life of 30 to 40 years.
Nature of EPS and XPS (Brittle)
Expanded Polystyrene Board due to the large area when pasting, the possibility of external walls cracking high level, especially in the paint surface. Usually by increasing the flexibility of cracking mortar to resist cracks that may arise. On the material itself, flexibility of XPS is much superior than EPS.
According to the above comparison, as wall insulation, the overall performance is better than EPS and powder particles of polystyrene insulation slurry, but the price is higher.
