NANJING LESUN SCREW CO.,LTD

LESUN XPS Foam Profile Extrusion technology

Physical extrusion of foamed profiles by supercritical CO2 injection has great potential to replace today's PS chemical foam  profiling standards. It is the most environmentally friendly PS foam profile technology. Thanks to its advanced technology, supercritical CO2 injection physical extrusion foam profile technology can make a great contribution to environmental protection.
LESUN XPS Foam Profile Extrusion technology
Superiority
·Higher safety than alkanes foaming profiles
· More environmentally friendly than chemical foaming and HFCs foam profile
·Extruded profiles with a lower carbon footprint than other methods of foaming 
·More beautiful surfaces and curved shapes
·Mechanical and aging resistance enhancements
·Lower density



Special technical features
·Special twin-screw extruder technology ensures rapid melting and uniform mixing without fluctuations
·Shorter start-up process and forming time thanks to the advanced LESUN Melt Cooler & Homogenizer
·Special self-regulating temperature control algorithm can effectively control temperature fluctuations
