Micro-lamellar talcs for foam composites

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.
