Abralon® J5 is a unique, multifunctional sanding material developed for tackling both smooth and profiled surfaces. Abralon J5 has a higher density foam layer which is 5 mm thick. The patented, flexible construction allows it to create a smooth sanding pattern on angled surfaces and edges while minimizing the risk of pressure marks. The flexible weave allows water and air to pass freely, resulting in a cleaner sanding process and a long lasting abrasive.
