1). Low conductivity factor 2). Good fire-blocking 3). Closed pore foaming, good damp-proof property 4). Good pliability 5). Beautiful appearance, easy to install 6). Safe (neither stimulate the skin nor harm health), Excellent performance of acid-resisting and alkali-resisting.
Kingflex Flexible Foam Rubber Insulation Pipe is a black, flexible elastomeric foam tube used to conserve energy and prevent condensation on piping applications. The tube closed cell properties create exceptional thermal and acoustic insulation. It is designed for the insulation of large surfaces, ideal for the insulation of pipes of large diameters. By reducing the number of sections required they simplify installation, saving on time and labor costs. Facing: Pipe can be covered with aluminum foil and adhesive paper. Technical Data Sheet
