Plasticized Poly(Vinyl Chloride) Filled with Waste Leather Particles

Abstract

Waste leather granules were incorporated into poly(vinyl chloride) polymer plasticized with di-octyl phthalate. The blend was prepared by a melt mixing process using a banbury mixer. The rheological behaviour of the mixture was recorded and the filled samples were tested for their physicomechanical properties. It was found that density, wear resistance and Shore D hardness of the specimen increases, whereas the tensile properties are considerably deteriorated with the incorporation of leather particles. A concentration of 40 parts per hundred parts of resin was estimated as the upper level of leather content, satisfying the needs of the design of final products with potential applications to the footwear industry. In order to improve mechanical properties, some treatments of the leather granules were applied, such as sieving and coating with ethylene vinyl acetate copolymer solution. Both those treatments seem to improve tensile strength. An increase up to 30% was observed when coated granules were used.

Processing and characterization of waste leather based polycaprolactone biocomposites

“…This could be due to the presence of leather which disrupts the regularity of chain structure. The crystallinity of PCL has been calculated using the equation , where Δ H mo is the enthalpy of fusion of 100% crystalline PCL taken as 135.4 J/g and Δ H m is the experimental heat of fusion of neat PCL and PCL composites.…”

Comparison of the effects of collagen and modified collagen fillers on the properties of XNBR rubber

“…There are also examples of using hydrolyzates of leather wastes to prepare biodegradable materials. 3,[4][5][6]7 Babanas et al 8,9 suggest also the possibility of using collagen as filler for PCV plasticized with octyl phthalate. Authors have observed that the increase in the leather powder content (10-60 parts by weight of collagen per 100 parts by weight of PCV) is accompanied by the increase in the density and hardness of the composites and deterioration in their mechanical properties.…”

Tannery Solid Waste to Treat Toxic Liquid Wastes: A New Holistic Paradigm

“…find use in shoe industry (Madera-Santana et al, 1998;Madera-Santana and Moreno, 1999;Abanas et al, 2001). The kinetics of grafting of glycidyl methacrylate (GMA) onto leather was studied with different chemical initiation systems (Shaffei et al, 2008).…”
