Analysis Mechanics and Thermal Composites Thermoplastic High Density Polyethylene with Zeolite Modification Filler

Erna Frida, Nurdin Bukit, Fynnisa Zebua


The purpose of the study to determine the thermal properties and mechanical properties of thermoplastic composites of high density polyethylene (HDPE) with filler natural zeolite modified with cetyl trimethyl ammonium bromide (CTAB) and purification of the calcination process.

Composite manufacture begins with a blens of calcined natural zeolites and zeolite synthesis CTAB. Then, the mixing of materials in an internal mixer at a temperature of 150oC laboplastomil for 9 minutes. The results of the internal mixer and molded by hot press and cold press sheets that subsequently result in a dumbell with JIS K 6781 standard mechanical tests, ASTM D 3418-03 analysis thermal.

Mechanical analysis results showed values ??of tensile strength and elongation at break of HDPE with the highest composite filler modified zeolite CTAB/PE-g-MA at 24.964 MPa and 398.89 mm. The Young 's modulus of the highest indicated HDPE composites with zeolite filler CTAB was 720.76 MPa. While the results of the thermal analysis shows the value of the highest melting point and decomposition on HDPE composites with zeolite calcined/PE-g-MA at 151.230C and 488.230C.
