Flame retardant corrugated plastic sheet (fireproof corrugated plastic sheet)

Time : 2019-12-07 Hits : 54

There are many types of corrugated plastic sheet, which can be classified according to their characteristics: flame-retardant corrugated plastic sheet (also known as fire-resistant corrugated plastic sheet), antistatic corrugated plastic sheet, conductive corrugated plastic sheet, anti-UV corrugated plastic sheet, corona corrugated plastic sheet (advertising board), ordinary corrugated plastic sheet. The following introduces the flame-retardant corrugated plastic sheet(fire-proof corrugated plastic sheet).

The flame-retardant corrugated plastic sheet (fire-proof corrugated plastic sheet) is added with flame retardant masterbatch to the raw materials when the sheet is produced, so that the flame retardant masterbatch and pp raw material are evenly stirred, and then extruded by high temperature hot melt extrusion.

There are three levels of flame-retardant corrugated plastic sheet:

V0: After two 10-second burn tests, the flame goes out within 15 seconds. 

V1: After two 10-second burn tests, the flame goes out within 30 seconds. 

V2: After two 10-second burn tests, the flame goes out within 60 seconds.


Many users have misunderstandings about flame retardant corrugated plastic sheet (fireproof corrugated plastic sheet) and believe that this type of board is incombustible. In fact, flame retardant corrugated plastic sheet will burn when they encounter open flames.  The real effect of flame-retardant corrugated plastic sheet is that the board will burn when it encounters an open flame, but when the board leaves the fire, it will automatically stop burning, instead of being ignited like other ordinary plastic boards Later became itself the source of fire.
