Environmentally-friendly PVC Plasticizers (Non-phthalate Plasticizers)

Environmentally-friendly PVC Plasticizers

Awareness is increasing regarding the environment and the safety of plasticizers and a response is being demanded in raw materials as well. DIC is working to develop plasticizers (non-phthalate) that accommodate usage restrictions for Endocrine Disrupting Chemicals and food utensils, containers and packaging, and toys. Examples of major applications and representative product numbers of non-phthalate plasticizers are shown below.

Major Applications & Representative Product Numbers

  • Food utensils/containers and packaging

    • Polyester, because it excels in non-volatility, oil resistance, and non-migration compared to DEHP (DOP).
    • Starting with the Japan Hygienic PVC Association's Positive List (JHP PL), DIC stocks many products that are compliant with domestic and international inventories.

    Representative product numbers
    Polycizer W-1020-EL, W-1410-EL
    Monocizer W-242

  • Gloves/toys

    DIC stocks many plasticizers that are suitable in fields with restrictions on the use of phthalic ester (phthalate) represented by DEHP (DOP).
    Representative product numbers
    Polycizer W-230-H
    Monocizer W-705, W-150, PB-3A
