Advantages and disadvantages of polyethylene plastic foam board insulation Interior

  Polyethylene plastic foam board is one of the three common interior wall insulation material. Also known as foam board, EPS board, white object from the polystyrene beads containing a volatile liquid foaming agent upon heating advance and heated in the mold and molding. It has fine features of its closed cell structure, mainly used for building walls, roof insulation, insulation and other composite panels. EPS is divided into expansion board (benzene board) and Continuous Extrusion plate XPS (extruded plate). Polystyrene recycling is a strong trend around the world today.

  Polyethylene plastic foam board Advantages:

1, polyethylene plastic foam board density coefficient, good impact resistance, have the ability to change and respond by the shape of the external impact force buffering;

2, with independent bubble structure, a small area of ​​damage will not affect the entire surface of the wall;

3, low water absorption, good anti-permeability, can effectively avoid the damp moldy walls or fall off the wall;

4, the temperature is not affected. At high temperature, polystyrene foam board will not melt and flow due to high temperature, it will not break if the temperature is too low;

5, polystyrene foam is recyclable material that can be recycled, the degree of recycling plastics is the highest;

6, in the production process does not use freon;

7, full life cycle energy consumption of plastics is the lowest.

  Polyethylene plastic foam board disadvantages:

1, the construction needs linked network, the construction process cumbersome, long duration;

2, flammable, have toxic gases after combustion. Common polystyrene foam insulation board is easy to burn, toxic smoke produced by combustion, even after adding a flame retardant, it can only reach B combustibility grade;

3, the strength of the material is poor, prone to cracking, insulation shedding phenomenon is relatively common;

4, polystyrene foam insulation board need to enhance the process when the tiles because of its limited strength, load-bearing ability;

5, unstable quality polyethylene plastic foam board, because the material before the factory needs a period of time, after a period of maturity can only be used, if uncured thorough, quality will not be guaranteed, leading to foam board shrinkage cracking.
