FAQ About Plasticizers for Polyurethane
Plasticizers are substances that are added to plastics to give them flexibility and make them easier to process.
The plasticizer penetrates into intermolecular spaces of polyurethane, weakening the intermolecular forces, and making each of the molecular chains easier to move, so the glass transition point of the polyurethane becomes lower.
Thus, the plasticizer gives the polyurethane flexibility.
