polymer plasticizer

    Polymers - Michigan State University

    The introduction of small molecular compounds called plasticizers into the polymer matrix increases the interchain spacing, allowing chain movement at lower temperatures. with a resulting decrease in T g. The outgassing of plasticizers used to modify interior plastic components of automobiles produces the "new-car smell" to which we are accustomed.

    Natural-based plasticizers and biopolymer films: A review .

    In polymer science, plasticizers can be either defined as internal or external. External plasticizers are low volatile substances that are added to polymers. In this case, plasticizer molecules interact with polymer chains, but are not chemically attached to them by primary bonds and can, therefore, be lost by evaporation, migration or extraction.

    Plasticizer - Wikipedia

    For plastics such as PVC, the more plasticizer added, the lower their cold flex temperature will be. Plastic items containing plasticizers can exhibit improved flexibility and durability. Plasticizers can become available for exposure due to migration and abrasion of the plastic since they are not bound to the polymer matrix.

    Plastic - The polymers | Britannica

    Plasticizers are used to change the T g of a polymer. Polyvinyl chloride (PVC), for instance, is often mixed with nonvolatile liquids for this reason. Vinyl siding used on homes requires an unplasticized, rigid PVC with a T g of 85 to 90 °C (185 to 195 °F).
