High r value extruded polystyrene insulation XPS foam board
XPS foam insulation board process : Polystyrene Granule, Talcum Powder, Master batch, Blowing Agent , and fire retardant are mixed and melted in Extruder. The melt material will be extruded out of Slot Die, then through Calibrator for forming the panel shap. After cooling, cutting, edge trimming, packaged to finished product.
XPS board feature:
2, Water-proof, stable performance
Characteristics of XPS internal obturator honeycomb structure and polystyrene molecule itself does not absorb water, effectively prevent the penetration and the spread of water molecules, effectively avoid the disadvantage of leaking, penetration, frost and condensation caused by plate decomposition aging of other similar material..
3, High compressive strength, superior impact
Unique molecular arrangement and the stability of foam pore structure, make its high compressive strength, impact resistance, strong, according to XPS of different type and thickness of the compressive strength of up to more than 150~800Kpa, under various system loads on the ground.
4, Long-service life, excellence quality
Polystyrene itself has extremely stable chemical properties, resist aging after long time use.It does not produce harmful substances decomposition, good quality of water-proof and anti-moisture can ensure that even under very high&low temperature environment it can still maintain its superior performance.
