Geon® Performance Solutions 180 Series 180X7 Polyvinyl Chloride Homopolymer (PVC Homopolymer)
Categories:	Polymer; Thermoplastic; Vinyl (PVC)
Material Notes:	Geon® 180X7 is low molecular weight homopolymer resin that provides good chemical foam characteristics with excellent overblow resistance. The modified rhelogy of Geon® 180X7 provides increased viscosity and yield. Geon® 180X7 is recommended for applications where high Brookfield Viscosity and yield are required such as higly plasticized low density chemically blown foams, highly plasticized formulations, and weather stripping. Note: The value set forth represent typical values and PolyOne Corporation, therefore, makes no representation that the material in any particular shipment will conform to the listed properties. Packaging: This resin is shipped in multi-wall paper bags, net weight 50 lbs, 2500 lbs per pallet. Information shown on the package includes commercial identification number, lot and weight. Geon® ALTC and ASTM D638 (formulation): 100phr Geon® 180X7, 57phr DINP, 3phr ESO, and 2phr Therm-Chek SP 120 LOHF Geon® STP 390 (formulation): 100phr Geon® 180X7, and 60phr DOP Geon Performance Solutions was created from PolyOne in 2019.
