Methyl Acetyl Ricinoleate as Polyvinyl Chloride Plasticizer
In this study, an additive derived from castor oil (methyl acetyl ricinoleate—MAR) was tested as a plasticizer for PVC. MAR was added to PVC in a range of 50–90 PHR and the increase of the plasticizer content had a great effect on maximum tension and tension at 100% of PVC samples.
Application of Different Vegetable Oils as Processing Aids
(1) The use of processing oils or plasticizers is by far the most effective way to enhance the interaction between the rubber and filler by increasing the compatibility. (2) Petroleum oils with polycyclic aromatic hydrocarbons (PAHs) are generated via the petroleum refining process.
New developments in vegetable oil materials science - AOCS
Vegetable oils are a mixture of unsaturated fatty acids with double bonds that act as reactive sites where the molecules can be chemically modified. Oleic acid, linoleic acid, and linolenic acid contain one, two, and three double bonds, respectively.
Role of the Oxethyl Unit in the Structure of Vegetable Oil
Owing to the excellent plasticization of DA-8, the performances of PVC-DA-8 were comparable or better than that of the PVC plasticized using commercial dioctyl terephthalate (DOTP). The simple but efficient method of this study provides a new avenue for the preparation of vegetable oil-based plasticizers for PVC.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Bio-based Plasticizers – They are based on epoxidized soybean oil (ESBO), epoxidized linseed oil (ELO), castor oil, palm oil, other vegetable oils, starches, sugars etc. Others – Includes Phosphates, Chlorinated Paraffins, Alkyl Sulfonic Acid Esters and more When added to polymer, these plasticizers provide several benefits as listed below.
- Is bio-based plasticizer B good for PVC?
- The hardness of b/PVC was greater than that of the others, which indicated that bio-based plasticizer b for PVC was not as good as that of the others; the harnesses of a/PVC and c/PVC (containing a benzene ring plasticizer) showed little difference.
- Is acetylated castor oil a bio-based plasticizer?
- Although acetylated castor oil has excellent performance as the bio-based plasticizer and has realized industrialized production, the price of it is three to four times more expensive than phthalates, which limited its utilization (Bocque et al., 2016).
- What are the Tg values of PVC films with Bio-Base plasticizers?
- The Tg values of the PVC films with bio-base plasticizers a, b, c and DOP were 30.6˚C, 45.3˚C, 23.6˚C and 40.6˚C, respectively. In contrast, the plasticizing effects of compound b with the alkyl diacid modification was superior to those of the plasticizers a, c and DOP containing benzene ring at low temperature.
- Are PVC films a good plasticizer?
- The mechanical properties of the PVC films are a good effective way to evaluate the efficiency of plasticizers, as shown in Table 2. The mechanical properties of the a/PVC and c/PVC films are obviously better than that of b/PVC films, and are as good as that of the PVC films plasticized by the DOP.
- What are the aims of adding plasticizers in plastic products?
- The aims of the addition of plasticizers in plastic products are to increase the flexibility and elongation; reduce the elastic modulus, glass transition temperature (Tg) and brittleness temperature of the plasticized products; and make the plastic products have excellent processability. 3.2.1. Mechanical properties
- Which Bio-Base plasticizer has a better plasticizing effect at low temperature?
- The FT-IR of PVC films showed that the downfield shifts of the —CH—Cl groups of the PVC plasticized with a and c were greater than that of b/PVC. The bio-base plasticizers b had a better plasticizing effect at low temperature. 1. Introduction
