Linear 911P is a linear C9, C10 and C11 phthalate plasticizer produced through esterification of mixed C911 alcohol and Phthalic Anhydride. It is used as a primary plasticizer for polyvinyl chloride (PVC) and copolymer resin applications where good low temperature flexibility is required, including outdoor applications such as vinyl coated fabric, vinyl roofing, or wire insulation. Linear 911P offers good weathering compared to branched phthalate esters making it a choice plasticizer for premium flexible PVC products. It shows superior permanence, good efficiency, good UV resistance, low volatility, and retention under heat aging in vinyl applications. It is recommended in automotive applications due to its low fogging performance. It is suited for sheeting, film extrusion, and vinyl dispersions. When compared to branched plasticizers, Linear 911P has a lower viscosity allowing for faster processing, faster dry-blending times, and lower plastisol and melt viscosities.
