How To Identify Polyethylene Fire Retardant Mar 09, 2017

1. weighing principle: the real proportion of ultra high molecular weight polyethylene products at 0.93 between 0.95 and less dense, and floats on the water surface, if not pure polyethylene material, will sink to the bottom.

2. the Visual method: true ultra-high molecular weight polyethylene surface smooth and uniform, smooth, shiny and cut very even, if not pure polyethylene color dark and uneven density.

3. edge testing room: pure ultra high molecular weight polyethylene flanged end surface round, uniform, smooth, if not pure polyethylene flanged end surface crack and slag off occurs when the heating flange.

4. temperature measurement: pure ultra high molecular weight polyethylene products, at 200 degrees Celsius is not melting, does not deform, but will soften, if not pure polyethylene at 200 degrees Celsius is deformation.
