Analysis of natural rubber compounds with filler Of Oil Palm Empty Bunches Powder and Carbon Black

Abstract

The study aimed to determine the effect of the addition of carbon black (CB) and Palm Empty Bunch Powder (OPBEP) as a filler in natural rubber compounds on thermal and transmittance properties. The composting method is done at the Open mill. The process of mixing natural rubber with additives, curative agents, activators, accelerator materials and nano OPBEP and CB with variations (0;2; 4; 6; 8)% wt. The results of the study were obtained. FTIR results from coumpound with CB and OPBEP fillers as a whole showed almost the same results. This is due to modifications so there is a possibility of overlapping with uptake on other bands. There is a peak of 2912 C – H asymmetric symmetric stretching vibrations of octadecylamine, respectively. Bending vibration of C – H in the = CH group of 3,4- or 1,2-units. The thermal properties of the DSC thermogram obtained an increase in the melting point and cross-linking with an increase in the content of the OPBA element compared with no filler as well as the CB / filler. In general, a compound with OPBEP filler and CB can be used as a technical product that has more mechanical properties.

Novel Solvent–Latex Mixing: Thermal Insulation Performance of Silica Aerogel/Natural Rubber Composite

“…The T g is an important physical property of polymer, i.e., when the environment temperature approaches T g , a transition state of amorphous polymer changes from glassy states to rubbery states [ 24 ]. In terms of chain structure, this temperature provides relaxation of the rigid chains turning to the movable chains [ 25 , 26 ]. DSC thermogram ( Figure 9 ) of the neat NR and silica aerogel/NR composites show that the T g of the composites was ca.…”

“…−61 °C which is similar to T g of the NR sheet. The indistinguishable T g of the neat NR and their composites revealed no significant filler effect on the T g of composites [ 26 ]. Zhang et al prepared NR composite using cellulose nanocrystals as fillers had reported that filler did not affect the T g of NR composites [ 27 ] In addition, the T g of the composites showed extremely below than room temperature due to intrinsic T g of the NR that contributed to the composite ability to retain flexibility at room temperature or higher [ 20 ].…”

Preparation and characterization of non‐vulcanized natural rubber‐based cocoa pod husk composites

“…The glass transition temperature ( T g ) is an important physical property of a polymer that causes the polymer to have resistance to heat or varying temperatures. When the outside temperature approaches the glass transition temperature, a polymer undergoes a change from a hard rigid state to a soft one like rubber 28 . DSC curves of all samples (Figure 2) and their derivative heat flows (Figure 2 inset) show that the glass transition temperature ( T g ) of the neat NR at −65.1°C.…”
