Foamed Cushioning Pellet Compound (PLA/PBAT)

About This Product

Foamed Cushioning Pellet Compound is a PLA/PBAT foaming grade supplied as a pellet compound for foam extrusion into loose cushioning. The blend is built around the melt strength a foam needs: PBAT gives the melt the extensibility to stretch around an expanding bubble without tearing the cell wall, and PLA gives that wall its stiffness once cooled. EPE and EPP cushioning perform well and are almost never recovered from a domestic waste stream, being light, bulky, low-value material that leaves the house in the bin. This foaming grade produces equivalent cushioning in a biodegradable polymer. Foam density and cell structure govern the cushioning curve, which is matched to the mass of the product and the drop height the pack is designed against. What the foam is doing is compressing gas in closed cells and buckling the walls around it, and that sets the trade: too light a foam bottoms out under a heavy product and passes the impact to the article, while too dense a pellet is stiff enough to transmit the shock straight through. Supplied as a raw material for processing on the buyer's own line. We do not produce finished articles. It is used in protective cushioning, in transit packaging and as an EPE and EPP replacement. Bio Green Chem supplies Foamed Cushioning Pellet Compound to specification on foam density, pellet size and cell structure, and on the product mass and drop height the pack is designed against.
