Effect of Modified Cardanol as Secondary Plasticizer on
a plasticizer can make PVC become soft and moldable by increasing the motion of PVC molecules.39 Therefore, it is crucial to optimize the formulation of plasticizers to boost the performance of PVC blends. The tensile strength and elongation at break of the blends are shown in Table 3. MC-0 has a tensile strength of 17.7 MPa, and increasing the MC
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. 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.

Structure Design, Performance Simulation and Plasticizing
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. In this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four different diols
Plasticizers in Paint & Coatings: Uses, Types and Selection
Phthalate-based Plasticizers Di-n-octyl phthalate (DOP) DOP or DnOP is light-colored, low volatility & odorless liquid. It was the most commonly used all-purpose plasticizer, although mainly used for polyvinyl chloride (PVC) resins. It is insoluble in water & has a low viscosity of 56 mPa.s at 25°C. DOP features:
- What is a plasticizer in PVC?
- A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced. Liquids are usually called “plasticizers”, whereas solids like nitrile rubbers, compatible polyesters and some polyacrylates are called plastifiers or flexibilizers.
- What is a nonmigrating plasticizer?
- These nonmigrating plasticizers are very useful in highly demanding products such as PVC roofing membranes and PVC geomembranes. They are also effective in reducing the Tg of the product. 24.12. Phosphate Esters One of the very first plasticizers proposed for PVC was the phosphate ester tricresyl phosphate.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- What polymers use plasticizers?
- Approximately 90% of these plasticizers are used in the production of plasticized or flexible polyvinyl chloride (PVC) products. Other polymer systems that use small amounts of plasticizers include polyvinyl butyral (PVB), acrylic polymers, poly (vinylidene chloride), nylon, polyolefins, polyurethanes, and certain fluoroplastics.
- What is Plasticized PVC used for?
- One major use of plasticized PVC is automotive underbody coatings; these products are highly filled plastisols that are mostly commonly based upon GP plasticizers often with a fast fusing plasticizer added to improve processability; however, plasticizer volatility can be a major concern. 24.17. Plasticizers for Other Polymers
- Are new plasticizers better than DOP?
- The tensile strength and elongation at break studies showed no significant differences between new plasticizers and DOP. Besides, new plasticizers presented a lower viscosity than DOP, which is very important in PVC plastics production.
