Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of products. Examples include: Unplasticized PVC (or rigid PVC) is used in applications such as pipes, siding, and window profiles.

Biobased Thermosetting Polyester Resin for High-Performance
Reducing the dependency from petroleum-based monomers and crosslinkers is an increasingly important goal for the plastics industry. This is being enabled by the growing diversity and availability of alternative biobased products derived from renewable resources, some of which are compatible with the production of more sustainable resins for high-performance applications. This paper presents
- What is bio-based Orthophthalic polyester resin (resin-b)?
- 2.1. Materials Bio-based orthophthalic polyester resin (Resin-B) was used as a polymer matrix for glass fibre impregnation during the production of a bio-based GFRP composite (GFRP-B). Resin-B was produced by synthesising monomers (diacids and diols) derived from renewable raw materials.
- Which polyester resin has the highest modulus of elasticity?
- The results presented here also evidenced that the total replacement of PA by FDCA (UPR100) provided the highest modulus of elasticity. By contrast, the UPR100 polyester resins show lower UTS (−8%) and elongation capacity (−37%) when compared to the UPR0.
- Are linear polyester resins good for topcoat and clearcoat?
- For example, linear polyester resins can be used to provide better scratch resistance, but their traditional structure results in reduced hardness and chemical resistance — equally valuable properties in topcoat and clearcoat applications.
- Can biobased thermoset polyester resins be developed from renewable sources?
- This paper investigates novel routes for the development of biobased thermoset polyester resins from raw materials derived from renewable sources.
- Can bio-based thermoset resins reduce styrene content?
- The previous research efforts on biobased thermoset resins focused on formulations that aimed at increasing the biocontent of the unsaturated polyester (UP) backbone (5−8) and at decreasing the styrene content by reactive diluents derived from bio- or less toxic counterparts.
- What is the difference between upr0 and upr100 polyester resins?
- By contrast, the UPR100 polyester resins show lower UTS (−8%) and elongation capacity (−37%) when compared to the UPR0. The outlier shown in Figure 6 c was disregarded for calculating the mean of the UPR100 strains. Thus, the mean strain at break was 1.5%.
