Natural-based plasticizers and biopolymer films: A review
1. Introduction. Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives [1].The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (T g).
Research progress of novel bio-based plasticizers and their
Biomass renewable resources have wide range of sources and low prices, and the chemicals obtained from them have various structures, which can provide a huge platform to design novel PVC plasticizers with the aim of replacing traditional phthalate plasticizers.
Plasticizers: Types, Uses, Classification, Selection & Regulation
A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.

Adipate plasticizers. Jayflex adipate plasticizers can be used as a primary plasticizer but, more typically, are used in blends with general-purpose phthalates to improve low temperature properties.
Plasticizers derived from cardanol: synthesis and
A series of plasticized PVC test specimens with different plasticizers were prepared. The compositions of different formulas are shown in Table 1. First, PVC powder, plasticizer, and thermal stabilizers were mixed using a mechanical mixer at room temperature for 5 min.
- What is the role of plasticizers in polymers?
- The primary role of plasticizers is to improve the flexibility and processability of polymers by lowering the second order transition temperature . Plasticizers are actually low molecular weight (MW) resins or liquids, which form secondary bonds to polymer chains and spread them apart.
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
- Why are plasticizer prices rising in Asia-Pacific?
- Asia The price trend for plasticizers showed an upwards trend in the the Asia-Pacific region during the first quarter owing to the domestic polymer segment's increased demand for the product as a result of better offtakes from China’s construction sector.
- Can plasticizers reduce material degradation over time?
- The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
- What are low molecular weight plasticizers?
- Low molecular weight plasticizers are added before or during the processing to reduce the melt processing temperature. However, these low molecular weight plasticizers may have some drawbacks, such as volatility, high water solubility, and insufficient compatibility with CA.
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
