PLASTICIZERS FOR PVC - Hallstar Industrial

Polymerics are used to provide flexibility, softness and lower modulus values, and can maintain these characteristics after exposure of the Polyvinyl Chloride (PVC) compound to severe conditions or harsh environments.

Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of products. Examples include: Unplasticized PVC (or rigid PVC) is used in applications such as pipes, siding, and window profiles.

Plasticizer - an overview | ScienceDirect Topics

5.4.1.1 Plasticizers. Plasticizers are bulky organic molecules, generally 300–600 g/mole in molecular weight, and also somewhat polar so as to be compatible with the PVC matrix. Good plasticization involves interspersing plasticizer molecules between PVC chains, breaking the small amount of native PVC crystallinity, and internally lubricating

Role of Plasticizers in PVC Products | Bausano

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.
