LLDPE matrix with LDPE and UV stabilizer additive to evaluate the interface adhesion impact on the thermal and mechanical degradation

Abstract Linear low-density polyethylene (LLDPE) is a commodity material that has been increasingly used in various open environments owing to its versatile properties. The mechanical and thermal degradation processability properties can be enhanced by blending with other polymers or using different types of fillers adjust such fit the required applications. objective this work investigate polymer–polymer interface compare it polymer–additive (microparticles) terms structural changes impact on polymer environmental novelty how control adhesion at enhance selected without compromising LLDPE dried resins were compounded UV additive wt% content LDPE resin separately twin-screw extruder 180–200°C 150 rpm rotating speed die head produce 1 mm thickness sheets. Then prepared specimens cooled ambient temperature for testing. nuclear magnetic resonance results showed microparticles good phase compared blended samples LDPE. Moreover, gravimetric analysis blends decompose two steps high content. morphological images revealed cavities microstructure low weight percent inductive relatively weak interaction between components. present study conclusively demonstrates matrix more stable microparticle (UV stabilizer) than LDPE, which impacts environment durability outdoor application.
