This study aimed to prepare thermoplastic elastomeric nanocomposites with Low-Cost Hybrid Filler Oil Palm Boiler Ash/Carbon Black as New Material. Hybrid filler composites promise to overcome the limitations of composites. The effects offered by the matrix and filler are responsible for improving the properties of the composite. The preparation of thermoplastic elastomer was carried out in two stages. The first stage involves mixing a rubber compound with filler. The second stage is blending the compound, HDPE, and PE-g-MA using an Internal Mixer. The results show that the peak intensity increased along with the amount of OPBA in TPE. The increase in peak intensity was caused by the rise in the number of crystalline phases in the nanocomposite. In general, the absorption bands are almost the same. The samples analyzed showed absorption band vibrations (Si-O-Si), in-plane strain vibrations (Si-OH), and symmetric strain vibrations (Si-O-Si), C―H deformation, –CH symmetrical stretching of the CH2 group appeared on each sample that FTIR has analyzed. Thermoplastics show good interaction between filler and matrix, so it can be assumed that these interactions can improve the mechanical properties of TPE. Differential Scanning Calorimetry (DSC) shows an increase in the number of peaks in the sample with 60/40 phr filler.

The concept of hybrid fillers by combining several types of fillers, especially with the inclusion of nanoscale filler particles, has attracted the attention of many researchers. The addition of filler to the rubber compound can improve the thermal properties. This study aims to analyze the effect of filler hybrid oil palm boiler ash (OPBA) –bentonite on thermal characteristics natural rubber compounds. The coprecipitation method was used in preparing OPBA, and CTAB surfactant was added in bentonite preparation. Meanwhile, compound preparation was carried out by inserting SIR 20 into an open mill machine. Characterization was done by XRD, FTIR, SEM, mechanical and thermal properties. In general, the compounds did not show a change in peak position. Peaks of 2Ө = 44° and 64°. Bonds at 2849–2917 cm-1 were associated with asymmetric methyl stretching vibrations. The peaks of 1000–650 cm-1 showed C = C-H bending. The compound morphology shows torn lines with branching. Furthermore, in general, the mechanical properties of the compound increased with the addition of OPBA/bentonite filler. Differential Scanning Calorimetry compound data showed an increase in the number of peaks in the sample with 10 wt% filler.
