Improved mechanical properties and flame retardant of low density polyethylene (LDPE) with adding different percentages of powder carboxymethyl-cellulose (CMC)

Abstract

The mechanical properties of (LDPE-463): powder carboxymethyl-cellulose composite was assessed with respect to the effect of filler content carboxymethyl-cellulose varying from 1% to 10% by weight in the composite. Obvious improvement in the mechanical parameters was recorded best ratio 2.5% weight. The mechanical properties of loaded film have been evaluated through several parameters concerning the elastic deformation based on measuring the load – elongation characteristics. The behavior of the stress - strain curve was analyzed in terms of the cold drawing model. Experimental difficulties appeared above 3.5% mixing ratio, and these difficulties were due to the separation in phase which makes the sample processing so difficult. The elastic behavior increased with increasing carboxymethyl-cellulose filler up to 2.5 %. While 1% is the best ratio that achieved best flame retardant.
