Blending of SiO2 with LLDPE via extrusion 2 / Muhammad Ikmal Md Isa

Linear low density polyethylene (LLDPE) was blended with filler SiO2 at a ratio up to 6% by extrusion to study the mechanical characteristics of the product and compared it with other journal. The maleic anhydride (MA) was grafted into LLDPE-SiO2 to determine the possible reaction. The LLDPE-g-MA composite filled with SiO2 were extruded and meltpressed in order to prepared samples from characterization and mechanical properties test. The FTIR results showed the interaction between LLDPE-g-MA and SiO2 and it also will affect the mechanical strength. The result obtained from this study showed that the LLDPE/SiO2-g-MAH composite was successfully prepared. It showed 2% wt. of SiO2 have the highest tensile strength while 4% wt of SiO2 is the highest ductility. For the flexural test, flexural modulus and strength are increase with the wt.% of SiO2 increase. From this study, it is found that SiO2 and MA can improve the strength of polymer but must be at the right amount.
