DOI: 10.15406/mojfpt.2025.07.00231 Properties of plasticizers Typically, plasticizers have linear or cyclic carbon chain with an average molecular weight of 300 to 600. These are high boiling
Effect of different polyols as plasticizers in soy based
Polyols have been extensively used as plasticizers in the production of many bioplastics, mostly glycerol. The present work assesses the influence of the presence of four polyols (glycerol (GLY), ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG)) on the properties of bioplastics based on a soy protein isolate (SPI), which
A Comprehensive Review on the Emerging Roles of Nanofillers
The role of the plasticizer is to improve film flexibility, whereas the filler serves as a reinforcement medium. In recent years, much research attention has been shifted toward devising diverse methods for enhancing the performance of bioplastics, particularly in the utilization of environmentally benign nanoparticles to displace the

Indonesia (Note: chitosan for filler facilitate biodegradation by microbes and particularly advantageous in applications in bioplastics compared with synthetic material (Dhanikula and Pachagnula, 2004). 3 ) Plasticizer use of glycerol byproduct from the manufacture of biofuel (Note: on
The effect of glycerol addition as plasticizer
Bioplastic is one of the breakthroughs in the effort to reduce plastic waste. The bioplastic can be produced from microalgae with a high protein content, such as Spirulina platensis. The aim of...
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Can bio-based plasticizers replace conventional plastic goods?
- The challenge to implement this new class of natural-based plasticizers matches the increasing interest of material researchers and industries in new bio-based materials, made from renewable resources with the potential, not to totally replace but to reduce the use of conventional plastic goods.
- Why do biopolymers need plasticizers?
- However, they generally present poor mechanical properties regarding processability and end-use application, since the fragility and brittleness exhibited during thermoformation can limit their potential for application. In order to overcome this problem, plasticizers are added to provide the necessary workability to biopolymers.
- What are bio-plastics based biopolymers?
- Majority of bio-plastics are starch-based biopolymers which are storage polysaccharide of cereals, legumes and tubers and widely available. For processing of starch, flexibilizer and plasticizer such as sorbitol and glycerine are added.
- What is the optimum plasticizer composition for S platensis-based bioplastic film?
- The results show that the optimum plasticizer composition for this S. platensis-based bioplastic film was 30 wt%, which shows the tensile strength at 27.7 kgf/cm2 and elongation at 66%. The tensile strength was very close to that of commercial plastic bags. The elongation property should be improved in order to be utilized for plastic bags.
- Can plasticizers be used to make plastic products?
- The use of plasticizers for plastic products manufacture is not a new practice. Its application to modify polymer characteristics began in the 1800s. In these early days, manufacturers of celluloid or celluloid lacquers used natural camphor and castor oil for plasticization purposes, but these were unsatisfactory for many end uses.
