Bioplastic material has emerged as one solution to the environmental problem caused by commercial plastic. Several raw materials have been used for bioplastic production, such as cassava, potato, and sago starch. This research focused on studying the effect of fillers and plasticizers variation to tensile strength and its morphology by using sago starch/citric acid-based bioplastic. The comparison of sorbitol and glycerol role as the plasticizer and microcrystalline cellulose and carboxymethyl cellulose as fillers were observed. This study was conducted by mixed and heated sago starch and fillers together. Then, citric acid and plasticizers were employed in the mixture solution. Next, the mixture was heated for 24 h then molded. The concentration of fillers, plasticizers, and citric acid were used as an independent variable which the interaction among them were investigated using response surface methodology (RSM) based on Central Composite Design (CCD). ASTM D822 evaluated tensile strength, and the morphological analysis was observed by using scanning electron microscopy (SEM). The results showed that the highest tensile strengths were 8.23 MPa for the glycerol and CMC process and 15.84 MPa for the sorbitol and MCC process. It was found that sorbitol and microcrystalline cellulose (MCC) increased the value of tensile strength twofold more than other fillers and plasticizers. As for the response surface method, the results describe the significant interaction between plasticizer and filler. It showed the tendency of increasing the concentration of fillers and citric acid decreased the tensile strength.

“…When incorporated in higher amounts, they can significantly increase the overall stiffness of the composite. This increased stiffness can make the material less ductile and more prone to brittle failure, reducing its ability to elongate before breaking [49]. Essabir et al [25] investigated that the tensile strain values exhibited a decrease as the filler content decreased.…”

To minimize the cost of production and enhancement pipe quality, this research aims to gain insights into the physical and mechanical characteristics of high-performance polypropylene random filled with rigid inorganic calcium carbonate particles at various content levels, with a specific focus on how the toughness of PPR changes. Virgin Polypropylene Random PPR, a new material extracted from a homopolymer polypropylene, is used as a matrix with 10, 20, 30, 40, and 50 wt. % of CaCO3. The density, melt flow rate, tensile strength, tensile strain, modulus of elasticity, and hardness are used to evaluate the quality of the material. The results showed that the density, the modulus of elasticity, and the hardness increased with increasing the percentage of CaCO3. As the percentage of CaCO3 increased, the melt flow rate decreased. The tensile strength and strain increased to 28.7 MPa and 533.25%, respectively at 20 wt.% of CaCO3, with 14.8% and 6.65% reaching gains compared to the virgin PPR (25 MPa and 500%). The enhancement of the mechanical properties is thanks to the presence of stiffer and rigid particles of CaCO3 that act as a reinforcing agent. Moreover, when CaCO3 is well dispersed, it forms a strong bond with the polypropylene matrix, and facilitates the transfer of stress from the matrix to the fillers, resulting in increased stiffness. The optimum percentage of CaCO3 to add into the inner layer of extruded PPR pipes is at a composition of the filler of 20 wt. %.

“…Otherwise, simply reduce the cost price of the transformed material. It was observed that, despite the use of precipitated carbonate calcium as filler, particles have a very small nucleating effect on HDPE [7,8]. There are no strong molecular interactions between the polymer matrix and this filler.…”

The objective of this work is the preparation and the characterization of high density polyethylene /calcium carbonate (HDPE/CaCO 3 ) composites. Polyethylene composites, containing 10-35 wt.% of CaCO 3 and HDPE with MFI (Melt Flow index) (0.550 g/10 mn) were prepared with co-extrusion process using extruder type Cincinati 90D. Thermal and mechanical studies were made in order to determine the parameters for obtaining a material (corrugated pipe) with optimal properties. The composite viscosity increased with filler content, suggesting the formation of filler agglomerates. Thermal analysis shows that addition of 30% CaCO 3 increased the thermal stability of HDPE around 32°C, decreasing the processing temperature of composites in 15°C. Regarding to the mechanical tests, the ring stiffness of the composites decreased with the addition of CaCO 3 above 35 wt.%. According to the obtained results, we suggest that HDPE/CaCO 3 composites could be used in the pipe production where tensile strengths higher than 25 MPa are not required and for service temperatures between 30°C and 70°C.
