I. Introduction to XPS Foamed Board and BHDD series machines:
With good honeycomb texture of closed pore; lower density, water absorption, thermal-conductivity, and coefficient of vapour permeability than common foamed material; having good advantage of high strength, low density, corrosion resisting, anti-aging; low cost.
With good honeycomb texture of closed pore; lower density, water absorption, thermal-conductivity, and coefficient of vapour permeability than common foamed material; having good advantage of high strength, low density, corrosion resisting, anti-aging; low cost.
It is widely used in heat preservation and insulation of building industry, road, railway, airport, squre, and home decoration, etc. BHDD series of machines are combined by single and single screws specially for XPS board extrusion.
