BASF Palamoll® 656 Polymeric Plasticizer

Description: Palamoll® 656 is a high viscosity polymeric plasticizer that is compatible with PVC. It is based on adipic acid and polyhydric alcohols. It is resistant to oils, fats, aliphatic hydrocarbons, bitumen and water. It is soluble in organic esters, ketones, ethers, aromatic and chlorinated hydrocarbons Applications: Palamoll® 656 has very little tendency to migrate into other plastics or adhesives. It is highly resistant to animal, mineral and vegetable fats and oils and is used for protective aprons, gloves and boots. It is used in roofing systems and expansion joint tapes where bitumen, water and sunlight resistance is important. Palamoll® 656 is used in films that are coated with an adhesive such as electrical tape, decals anddecorative film. It should be preheated to 80°C before addition to the blender. The mixing cycle should continue until a temperature of 150° - 170°C is reached, depending on the amount of plasticizer. It has a higher molecular weight than monomeric plasticizers and must be processed at a higher fusion temperature.Notes: Properties for product in vinyl film, the specimens were prepared from compression-molded film of 60 mils gauge for the determination of torsional rigidity, 400 mils Shore A and D hardness and 20 mils for all other properties.Information provided by BASF
