Structure Design, Performance Simulation and Plasticizing
The mechanical properties of PVC blends plasticized by the four copolyesters including tensile and impact strength are measured and compared with the commercial plasticizer DOP. The stress–strain curve from the tensile test can be used to characterize the mechanical properties of PVC films.

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.

In PVC gloves produced in earlier times, phthalate plasticizers were used by 80% among the overall plasticizers, including DOP, DBP, DIBP, BBP, DINP, etc. DOP is called an all-round plasticizer because of its advantages of high plasticization performance, good PVC compatibility, low exudation, low volatility, softness, high brightness, etc.
- What is a plasticizer in PVC?
- A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced. Liquids are usually called “plasticizers”, whereas solids like nitrile rubbers, compatible polyesters and some polyacrylates are called plastifiers or flexibilizers.
- How do plasticizers affect the performance of PVC products?
- Plasticizers influence the flexibility, workability, and durability of PVC products. Choosing the right type of plasticizer can enhance the performance characteristics of PVC while also addressing environmental and health concerns.
- What is a primary plasticizer?
- Primary plasticizers are low-volatility liquids, whose polarity is such that they are sufficiently compatible with PVC and will not be readily squeezed out of plasticized PVC by moderate pressure. They are mainly responsible for providing flexibility. Examples include: monomeric, polymeric, epoxy, specialty flame-retardant plasticizers, etc.
- What is a good plasticizer molecule for PVC?
- An effective plasticizer molecule for PVC has two types of structural components: Non-polar component. The polar component of the molecule must be able to bind reversibly [not like vulcanized rubber] with the PVC polymer, thus softening the PVC.
- What are plasticizers used for?
- These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare. Plasticizers serve as essential additives in enhancing the performance of PVC. By reducing the glass transition temperature, they enable products to maintain functionality under various conditions.
- Why do we need plasticizers in polyvinyl chloride (PVC)?
- Plasticizers play a crucial role in the overall performance and usability of polyvinyl chloride (PVC). Their addition can significantly alter the mechanical properties of PVC, thereby expanding its application range.
