SphereCel PE is a core material made of polyester tissue which is volumized by embedding thermoplastic microspheres along with specialized binders and additives.
This product is very elastic and well drapeable when wet. This material can be wet out by side of the mold and transferred to the mold without tearing and ripping. Comparable to Coremat, U-pica, Matline, Vitelmat etc.
This material comes in 1mm/2mm/3mm/4mm/5mm thicknesses.
SphereCel PE should be placed between layers of fiberglass reinforcement in the lamination stage, not directly against the gelcoat layer.
