Add density and stiffness to foams with higher cell density
Our micro-lamellar range of talcs can improve the stiffness of foams at lower densities. This can optimize lightweight materials and lead to other benefits. Their micro-lamellar morphology generates a larger number of cell nuclei, resulting in finer cell structure and higher cell density.
- Increases cell density significantly
- Promotes fine and regular cell size
- Improves stiffness at lower density
- Optimizes lightweight materials
Using micro-lamellar talcs as nucleating agents in polypropylene results in foams with cell densities twice as high as those obtained with regular lamellar talc.
At this loading, using the injection-molding MuCell foaming process, a weight reduction of 10% can be achieved with the same specific elastic storage modulus as an unfilled solid polypropylene.
Micro-lamellar talc can also be used in polystyrene to achieve microcellular foams and has proven effective in polyolefins and polystyrene compounds.
