Mechanical Degradation an overview ScienceDirect Topics
Two roll milling and ball milling are the best process for the mechanical recycling of PU. Flexible PU can be grind using two-roll mill, whereas rigid PU through ball milling. The recycled powder can be used as a filler for the production of PU foam or elastomer.
Mechanical Recycling via Regrinding, Rebonding, Adhesive
2018. 1. 1. Grinding is a process of mechanical recycling, which involves generally two steps, i.e., grinding of PU foams into a fine powder and mixing of obtained powder with, e.g., polyol. The regrinding process can be also realized in the polyol and is called wet grinding. Two-roll mill: Reinforced PU foam (RRIM)
Introduction to rubber processing and safety issues HSE
2019. 12. 5. Polyurethanes (including PU foam production, reconstituted foam and conversion and rigid urethanes) usually onto a two- roll mill, roller die, twin-screw extruder, conveyor, skip hoist, or wheeled truck. Main mechanical hazards . Feeding ingredients and collecting compound .

2019. 7. 18. proaches including using a two -roll mill were also demon strated on a pilot-plant scale. The last published major efforts conducted in foam rec y cling were reported in 1995 1997. This has been the subject of a recent technical re-view . Some of the concl usions of that work were: 1) the economics of foam recycling by means of grinding
CHEMICAL DEGRADATION OF POLYURETHANE FOAM
The swelling ratio in toluene of the PENR decreased as a function of w-PUfd content due to an increase in chemical interactions. After blending the PENR with the STR-5L and vulcanizing agents using two-roll mill and then compression molding at 150 °C, the effects of w-PUfd content in PENR on the properties of cured STR-5L were investigated.
