Polyvinyl Chloride (PVC) Labware | Thermo Fisher Scientific - US
Polyvinyl chloride is transparent and has a slight bluish tint. When blended with phthalate ester plasticizers, PVC becomes soft and pliable and can be extruded into flexible tubing. Without a plasticizer, you get a ridged PVC pipe instead.
Triacetin as a Secondary PVC Plasticizer | SpringerLink
The use of biobased plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has become more attractive in the recent years in contrast with phthalate derivatives. In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC. TAG was added to PVC formulations from 10 up to 20 phr. The increase of the plasticizer
Methyl Acetyl Ricinoleate as Polyvinyl Chloride Plasticizer
PVC samples obtained using this bio-based plasticizer demonstrated good rheological properties [the increase of plasticizer content increased the MFI from 3.977 (50 PHR) up to 44.244 g.10 min 1 (90 PHR)] and proved to be thermally stable up to 200 °C.
Validation of a deplasticizer–ball milling method
In the present work, the complete separation of PVC and high-purity Cu from thin electric cables of various diameters and sizes was achieved via a combination of plasticizer extraction and ball milling—the latter with various ball sizes and rotational speeds.
Simultaneous recovery of high-purity copper and polyvinyl chloride
1 h shaking in the sieve shaker, a maximum separation rate of 77% was achieved and the purity of the obtained separated Cu reached >99.8%. 1. Introduction Polyvinyl chloride (PVC) has become an indispensable resin because of its high chemical and physical stability. Compared with other resins, PVC consists of a high percentage of Cl
- Which PVC plasticizer is best?
- The plasticizer with good plasticity, flame retardancy and migration resistance. VA8-P plasticized PVC exhibits good plasticity at low temperature. VA8-P plasticized PVC obtains the UL-94 VTM-0 grade, superior to DOP. VA8-P plasticized PVC migrates very little in organic solvents.
- Are flexible poly (vinyl chloride) plasticizers flammable?
- Nevertheless, the combustibility of flexible poly (vinyl chloride) (PVC) products containing high content plasticizers is frequently disregarded. The development of PVC functional plasticizers requires careful consideration of a good balance between flame retardancy, migration resistance and plasticity through molecular structure design.
- Why does polyvinyl chloride need a plasticizer?
- It is widely acknowledged that the presence of dipole–dipole interactions among polyvinyl chloride molecules contributes to the inherent rigidity and brittleness of unmodified PVC products. Consequently, the incorporation of a significant amount of plasticizer is often necessary to disrupt the intermolecular interactions between polymer chains .
- Can highly plasticized PVC materials replace toxic phthalate plasticizers?
- The highly plasticized PVC materials are promising to find application in various fields as a replacement of plasticized PVC materials containing toxic phthalate plasticizers. The study provides new way for chemical transformation and improving added value of non-timber forest resources in plantation. 1. Introduction
- How are phthalate-free and highly plasticized polyvinyl chloride materials produced?
- Phthalate-free and highly plasticized polyvinyl chloride (PVC) materials were produced via substituting chlorine of PVC with dehydroabietic acid derivatives containing primary amine groups.
- What is polyvinyl chloride (PVC) used for?
- It can be used to synthesis various kinds of fine chemical products. Polyvinyl chloride (PVC), as one of the most widely used general purpose plastics, is widely used in pipe, wire and cable, packaging film, bottle and foaming material due to its excellent flame retardancy, chemical resistance, mechanical strength and electrical insulation .
