Thermal stability of poly(2-ethylhexyl acrylates) used as
New area applications for polymeric plasticizers based on 2-ethylhexyl acrylate (2-EHA) are technical products where the thermal resistance plays the major role. The successful development of high performance acrylic polymers in form of copolymers and homopolymers used as PSA has been viewed as a classic example attesting to the importance of

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).
Plasticizers in Paint & Coatings: Uses, Types and Selection
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane. Di-iso-nonyl phthalate (DINP) & Di-iso-decyl phthalate (DIDP)
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.
- What are plasticizers & stabilizers?
- Plasticizers are one of the key materials which improve the characteristics of the final products such as flexibility, which would not be realized without it, to PVC and rubbers. PVC stabilizers are one of the essential materials for PVC to improve processability and characteristics of PVC products.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- Which plasticizer is better – low or high molecular weight?
- Poly (vinyl chloride), plasticized with low, medium, and high molecular weight plasticizers, is an excellent example of such behavior. Low molecular weight plasticizers are more efficient but suffer from impermanence. High molecular weight plasticizers have superior permanence and better physical and electrical properties, but are less efficient.
- Why are polymeric plasticizers used in PVC?
- The use of polymeric plasticizers in PVC is not characteristic in one sense. PVC is a very viscous polymer and is difficult to process in commercial equipment. At temperatures high enough to give good flow, PVC undergoes rapid decomposition. Consequently, monomeric plasticizers were eagerly adopted by PVC processors.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- 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.
