What is XPS?

XPS (extruded polystyrene) insulation board, is a kind of good insulation material, which is a high quality foam product characterized by smooth skin with a closed-cell structure that looks like a mass of uniform bubbles with common walls between them. There are few, if any, voids between the cells, top and bottom skin.

Features of XPS
Comparing with other traditional insulation materials, such as EPS, PU and Rock wool, XPS is improved in insulation, moistureproof, compressive strength, durability, convenient installation and low cost.
As an ideal material, XPS is widely applied to heat preservation and insulation systems, moistureproof and obstruct systems, with promising potential market.

The Advantages of Our XPS Line
1. Economical Investment: The XPS Insulation Board Production Lines from HiSuccess International is of reasonable price with updated technology and high quality. The machinery is much cheaper than the lines with same capacities from Europe. Economical investment is also a kind of important low-carbon economy.
2. Wide Raw Materials Range: The raw materials can use 100% recycle materials, such as recycled EPS, XPS and GPPS as well as virgin GPPS as raw materials. It can reduce the cost of XPS board very much. The lines from Europe only can use virgin materials. The prices of recycled materials are much cheaper than virgin materials. Our lines are the environment friendly machinery.
3. Environment Friendly: The machinery can use LPG, butane and/or CO₂+Ethanol as foaming agent with updated technology, without harmful to the aerosphere. The processing and products are totally HCFC free and HFC free.
4. Flexible Capacities: We can adopt twin screws in first extruder, as well as single screw. Different combinations with different diameters and sizes in the first extruder and second extruder, we can get different capacities from 200kg per hour to 600kg per hour. It can fulfill the most of market requirements.
5. Rich Experience: We have rich experience to produce, install and operate XPS Production Line since 1998. The long list reference all over the world is the guarantee to provide qualified and excellent service to our clients in manufacturing, installation, commissioning, test production, training and after service.
6. Quality Certificates: The machinery has gotten the certificates from international inspecting organizations, such as CCC, CE, ASME, GOST and so on.
