Selecting Plasticizers for Adhesives and Sealants
By far, the largest application of plasticizers is as a flexibilizing additive in plastic products such as food packaging, wire and cable insulation and medical devices. In these markets plasticizers are mainly used with polyvinyl chloride (PVC), but many other rigid polymers are plasticized for practical use.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.

Eastman TOTM plasticizer (Tris (2-Ethylhexyl) Trimellitate) is the ideal PVC plasticizer for use in applications where low volatility is of supreme importance, such as wire and cable insulation and interior automotive. It also has properties that are required for dishwasher gaskets and photograph storage.
Preparation and characterization of polyvinyl alcohol
This PVA–starch composite, reinforced by pulp has great a novelty about producing various types of bio-degradable composite materials (such as packaging materials, plastics, consumer materials, agriculture materials, biomedical materials etc.) [ 19, 20 ], especially recycling the paper mills waste (sludge).
Influence of Polyol Plasticizers on the Properties
In this work, high-alcoholysis polyvinyl alcohol (PVA) films were fabricated by melt processing and the plasticizing effect of compound polyol plasticizers on PVA were investigated with X-ray diffraction (XRD), differential scanning calorimetry (DSC), rheological measurements, mechanical tests etc. Hydrogen bonding interactions occurred between PVA and plasticizer. With the increase of
- Which plasticizer is used to plasticize PVA resin with a DP of 2400?
- In this study, two types of frequently used plasticizers, glycerol (GLY) and diethanolamine (DEA), are chosen to plasticize PVA resin with a DP of 2400. Both PVA/plasticizer films possess excellent optical transmittance and mechanical ductility, whereas the films blended with DEA exhibit higher strength than the PVA/GLY films.
- Can PVA/DEA be plasticized in a viscous solution?
- To determine the differences during solution processing, the viscosity of PVA solutions with different CPVA and plasticizer contents is also characterized using a dissolved kettle equipped with an on-line viscometer, proving the better plasticization ability of PVA/DEA in viscous solutions.
- How to make PVA/CA/plasticizer blend films?
- The solution casting method was used to obtain the PVA/CA/plasticizer blend films. Firstly, CA and plasticizers (PEG, SOR) were dissolved in 5% TEA solution under magnetic stirring for 1 h at the 35 °C to prepare 6.0 wt % plasticized CA solutions.
- Can glycerol and diethanolamine be used to plasticize PVA resin?
- Optimization the plasticizing conditions is one means of addressing this issue. In this study, two types of frequently used plasticizers, glycerol (GLY) and diethanolamine (DEA), are chosen to plasticize PVA resin with a DP of 2400.
- Why is plasticized PVA better than Gly?
- The plasticized PVA system had better mechanical properties, manifested as higher strength and greater toughness of the PVA/DEA films compared to those of the GLY-containing congeners under the same conditions, while maintaining the transmittance.
- How do plasticizers interact with hydroxyl groups in the PVA chain?
- The added plasticizers interact with the hydroxyl group in the PVA chain to construct hydrogen bond networks, [42, 43] replacing hydrogen bonds in the inter- or intra-PVA chains, thus forming structures with differences in plasticizer dispersion.
