A plasticizer composition including a cyclohexane-1,2-diester-based material and diisononyl terephthalate. The plasticizer composition is superior to existing phthalate-based plasticizer products in terms of plasticization efficiency, volatile loss, and heat aging elongation retention rate, and can replace phthalate-based plasticizer products.

A manufacturing method of a symbol button for a vehicle includes: preparing a button body comprising a side portion, a top portion formed of a polymer material on which a metal is able to be plated; forming an electrically conductive layer on an outside of the button body using a conductive polymer material; forming a plating shielding layer in a form of a symbol using a material on which a metal is not able to be plated on the electrically conductive layer; and performing metal plating on the outside of the button body having the plating shielding layer.

A rigid polymeric modular flooring plank that contains chlorinated polyvinyl chloride (CPVC) in the core or base layer. The rigid polymeric modular flooring plank has at least a polymeric core or base layer, a decorative layer, and a wear layer located above the decorative layer. The CPVC can offset the negative effects from any plasticizer present in the core layer, and thus permits the core layer to include plasticized material such as from recycled or reclaimed sources including rework and scrap materials. Methods of making the planks are further described. A method to control dimensional stability of a polymeric flooring plank is further described.
