In addition, the secondary backing material, if applied, may include any synthetic resin that will integrally fuse with the extruded sheet. Preferably, the secondary backing comprises the same thermoplastic polyolefin polymer, copolymer or terpolymer as the primary backing. Optionally, the secondary back...
Oily Wastewaters In the present study, synthetic and real wastewaters were used to investigate the performance of polypropylene MF membranes. Model emulsions with 50 mg/L, 90 mg/L, and 150 mg/L oil concentration were prepared in the laboratory by mixing different amounts of oil concentrate and...
Char-forming organic fibres are either natural, such as cellulose and wool, or synthetic thermoplastics with aromatic structure such as some polyesters and polyamides. Other organic thermoplastic fibres, such as polyolefins, on the other hand, have poor or zero char-forming capability. When ...
