Title: A Review on Plasticizers and Eco-Friendly
Bioplasticizers are derived mainly from biomass sources including agricultural products, it’s by-products and waste. Regardless of the biomass source, ideal bioplasticizers are expected to be...
EST: Price indices for oilcrops and derived products
In the meantime, the vegetable oil index increased markedly, up 16.3 points (or 9.6 percent) from its level in September, to an all-time high. The latest increase of the oilseed index broadly reflected firmer international rapeseed and sunflowerseed prices, which more than offset lower soybean prices.
Plasticizers Derived from Biomass Resources: A Short Review
Polyvinyl chloride (PVC) plasticizers derived from biomass resources (vegetable oil, cardanol, vegetable fatty acid, glycerol and citric acid) have been widely studied to replace petroleum-based o -phthalate plasticizers.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Due to its low cost and generally good performance, DEHP is widely employed as a plasticizer in manufacturing articles made of PVC. Melting point: 50°C Boiling point: 250 - 257°C at 0.5 kPa Structure of DEHP DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength.
Green plasticizers derived from soybean oil for poly(vinyl
Vegetable oil based plasticizers have potential use as nontoxic and sustainable plasticizer and as replacements for commonly used phthalate plasticizers.
- 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.
- 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
- Can bio-based plasticizers replace DOP?
- The bio-based plasticizers a and c derived from modified waste cooking oil using aromatic diacid could be used as temperature-resistant main plasticizers for the PVC to completely replace the DOP.
- 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.
- 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.
