Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.

Selecting Plasticizers for Adhesives and Sealants
Plasticizers are used in all types of adhesive and sealant formulations. They are used primarily to the final bond and to provide improved low-temperature properties. However, plasticizers can also supply additional benefits that are important to both the formulator and end-user.
Plasticisers - Information Center
The most common plasticisers include esters such as adipates, azelates, citrates, benzoates, ortho-phthalates, terephthalates, sebacates, and trimellitates.
ATBC, Acetyl Tri-n-Butyl Citrate
Phthalates command the market due to their low cost, ease of use and availability. Other common plasticizers include adipates, polymerics and trimellitates. Over 90 percent of plasticizer volume goes into flexible PVC applications.
- What is a citrate plasticizer?
- When added to polymers, citrate plasticizers offer good performance and excellent flexibility at low temperatures; being less volatile, they also offer good heat and light stability. Catagorised as non phthalates, citrates are ideal to be used in medical device, food packaging applications and pharmaceutical preparations.
- Which materials can be plasticized with citrates?
- Some properties of materials plasticized with citrates can match those plasticized with DOP but the cost of their production is substantially higher. Tri Butyl Citrate is a high boiling substance, is used as a solvent and plasticizer for polymers especially for PVC and its copolymers which are subsequently applied to food wrapping film.
- Why are citrate plasticizers not used in film applications?
- However, citrate plasticizers are highly volatile and a significant amount is lost due to this property. Citrates lack permanency. Hence, they are not employed in resilient applications like cables, flooring, or roofing. They induce more fogging in film applications.
- What are the different types of plasticiser chemistries?
- Some commonly used plasticiser chemistries are phthalates, terephthalates, cyclohexanoates, trimellitates, adipates, benzoates, citrates, and sebacates. General-purpose plasticisers such as DINP, DINCH, and DOTP are used in applications such as flooring, medical devices, food film wrap, and other high-volume applications.
- Are non phthalate plasticizers safe?
- Low Toxicity: Non-phthalate plasticizers are often considered safer for both humans and the environment. Good Performance: They provide similar flexibility and durability as phthalates. Regulatory Compliance: These plasticizers are more likely to meet modern environmental and health regulations. Dibasic Esters (DBE)
- What are the different types of plasticizers used in polymers?
- Oily, waxy,or fatty substances were applied as plasticizers. Other i nvention polymer matrix. poly- DL -lactide- co-glycolide (PLGA) were produced. plasticizer, PEG, was added to the polymers. It was degradation-controlled phase. The plasticizer accelerated polymer. The plasticizer dep ressed the burst effect for controlled phase.
