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
(PDF) Effect of Plasticizer Percentage on Thermal Properties
The effect of DOP plasticizer percentage on limiting oxygen index and thermal stability of plasticised PVC was investigated in this paper. DOP was added PVC with various quantities (20, 30, and 50

Effect of Modified Cardanol as Secondary Plasticizer
This study represents the first attempt to prepare a novel cardanol-based plasticizer. Modified cardanol (MC, i.e., phosphorylated cardanol) containing nitrogen and phosphoric acid groups was synthesized and then incorporated into polyvinyl chloride (PVC) as the secondary plasticizer for partial substitution of dioctyl phthalate (DOP). The molecular structure of MC was characterized by Fourier
A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of plasticizer needed to obtain a certain hardness or elongation is a measure of its efficiency.
Effect of various plasticizers and concentration on the
The present study investigated the effects of plasticizers (fructose, urea, tri‐ethylene glycol, and triethanolamine) with different concentrations on the physical, thermal, and mechanical properties of cassava‐starch‐based films. The film samples were prepared using casting methods.
Insulating Materials List - Professional Plastics
insulating properties are complemented by the high thermal conductivity. These include Macor ®, Alumina, and others. DELRIN: This Dupont acetal (POM) resin is made from polymerized formaldehyde and finds uses similar to nylon. The material is rigid and has excellent mechanical and electrical properties making its use common in
Effects of Thermal Curing Conditions on Drug Release from
This study aimed to investigate the effects of dry and humid heat curing on the physical and drug release properties of polyvinyl acetate–polyvinyl pyrrolidone matrices. Both conditions resulted in increased tablet hardness; tablets stored under humid conditions showed high plasticity and deformed during hardness testing.
Cellulose Acetate for Thermoplastic Foam Extrusion | IntechOpen
However, if the plasticizer content is too high, melt stiffness and melt strength may become too low for stable foam extrusion processes. By changing the plasticizer content or by using a more miscible plasticizer, excellent melt processing behavior as well as good thermal and rheological properties of CA can be achieved for foam extrusion.
Ranking Plasticizers for Polymers with Atomistic Simulations
Effects of plasticizers (glycerol, sorbitol, and 1:1 mixt. of glycerol and sorbitol) on moisture sorption characteristics of cassava starch films were investigated at three levels of plasticizer concn. (0, 20, and 40 g/100 g starch). The combined effects of relative humidity and plasticizer on mech. properties of starch films were also examd.
