PP, New Versus Recycled Material

Sample

Molen SP 179 94 as pellet and milled recycled material (powder) said to be of the same quality

 

Conditions

Measuring cell: DSC20

Pan: Aluminum standard 40 µl, pierced lid

Sample preparation: Powder, or disk cut from pellet

DSC measurement: Heating from 30 to 250ºC at 10 K/min

Atmosphere: Air, 50 cm3 /min



Conclusion

The two samples show the same melting behavior. As far as DSC is concerned, the two samples of polypropylene are therefore identical with respect to crystallite size distribution, melting range, crystallinity and hardness.
