Polyethylene Microspheres used in the composite industry include the following characteristics:

• Ideal for all applications where you require a smooth surface,
• Increase the mechanical strength of the finished compound, improving the aesthetical properties of the surface,
• They avoid the shrinkage phenomenon,
• They simplify the mixing and dispersion process of organic additives,
• They increase abrasion resistance of the final product.

The microspheres of PE, Microthene, are mainly used in SMC /BMC molding and in the pultrusion process.

The addition level goes up to 6% of the total resin weight.
