Uneven appearance of vacancies, such as: used as filler, sealant adherent, sealing strip in roof, wall, concrete slab, highway expansion joints. epp foam board can promote the setting of concrete by reducing the loss of heat and moisture. Using its low thermal conductivity, epp foam can be used as a roofing material for building roofing.

pp material can be used as a building material with good thermal insulation and sound insulation in the construction profession. Because of the low thermal conductivity, low water vapor permeability and high energy absorption of foamed PP, these functions together with its compressibility make it suitable for filling.
