Tospearl™ Plastic Additives Are Developed For Both Converters And Manufacturers
Momentive's Tospearl™ resins allow for higher quality and less downtime at the converter and faster extrusion while manufacturing films. No need to worry about adhesion on the finished roll or the inside of the bubble. Tospearl™ resins helps prevent film adhesion by decreasing the contact between film layers, lowering the coefficient of friction (COF) and thus, preventing them from sticking together.
The silicone helps improve film clarity while requiring lower usage levels than other antiblocks like silica, talc or mica. With Tospearl™, there is no need to worry about heat sealing issues like traditional migratory plastic additives.
Tospearl™ is available in a variety of particle sizes suitable for most film thicknesses. The diameter of the Tospearl™ resin bead should be approximately 40% of the skin layer thickness to provide the lowest possible COF which would assure adequate bead retention.
