Environmentally-friendly PVC Plasticizers (Non-phthalate 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
