Plasticizer Effects on Physical–Mechanical Properties
Plasticizers are generally nonvolatile, high boiling, low molecular weight compounds added to a polymer to improve its processability, flexibility, and stretchability by modifying the mechanical properties making the films more ductile, lowering the melt viscosity and the Tg of the product without altering the fundamental chemical character of
Effects of moisture content, wood species, and form of raw
High‐quality wood fiber‐reinforced composites are desirable products not only due to their outstanding mechanical properties, but also excellent appearance and weather resistance 10. However, at present, the vast majority of fibers for reinforcing WPCs are produced through a simple and rough processing of wood flour (wood fibers), including
Effects of bio-based plasticizers on mechanical and thermal
The effects of plasticizers on the mechanical, dynamic mechanical, and melt rheological properties of composites and the thermal migration of plasticizers were characterized. The results demonstrated that WPVC/ DBP and WPVC/EFAME composites had better elongation at break; however, composites with bio-based plasticizers exhibited significantly
Role of plasticizer and dispersion methods on the properties
The effect of clay pre‐dispersion in plasticizers was also evaluated using two mixing methods: sonication and mechanical mixture. A heterogenic dispersion of the clay in the PVC matrix and different plasticization regions were observed in thermal properties and in morphology results.

(PDF) Effect of Selected Commercial Plasticizers
Mechanical, thermal properties, and shape stability (warping effect) of 3D printed products can be improved just by the addition of appropriate plasticizer to polymeric blend.
Plasticizer Effect on Oxygen Permeability of β-Lactoglobulin
Plasticizer effect on oxygen permeability (OP) of β-lactoglobulin (β-Lg) films was studied. Propylene glycol (PG), glycerol (Gly), sorbitol (Sor), sucrose (Suc), and polyethylene glycol at MW 200 and 400 (PEG 200 and PEG 400, respectively) were studied due to their differences in composition, shape, and size. Suc-plasticized β-Lg films gave the best oxygen barrier (OP < 0.05 cm3·μm/m2
Effect of carboxymethyl cellulose concentration on physical
Cassava starch, the economically important agricultural commodity in Thailand, can readily be cast into films. However, the cassava starch film is brittle and weak, leading to inadequate mechanical properties. The properties of starch film can be improved by adding plasticizers and blending with the other biopolymers. Cassava starch (5%w/v) based films plasticized with glycerol (30 g/100 g
Blending of recycled mixed polyolefins with recycled
Each of these materials had one type of mechanical property in common with the high quality rPP, these being Young’s modulus and toughness respectively. Blends were made at different concentrations (0-50% in steps of 10%) and injection moulded into test samples.

Experimental investigation into the effects of adhesion wear
Glass fiber reinforced plastics (GFRP) are widely used in the design of rocket fairing and wind turbine blades due to their attractive advantages, such as lightweight, high strength and hardness, and high-temperature resistance. Its surface integrity characteristics, including surface roughness and surface morphology, influence the aerodynamic performance significantly. Belt grinding has been
