Products > Pearlcomb > About Pearlcomb PEARLCOMB can be shaped into diverse forms (cylinders, flat plates, spheres, cones, etc.) by our outstanding sintering technology. The PEARLCOMB Series products are actually manufactured by Japan Prouder Ltd., our partner that has already acquired ISO certification for its quality management system (JQA-QMA12047). * Being a plastic, PEARLCOMB is resistant to shocks, is lightweight and has excellent corrosion resistance. It can be washed and reclaimed. * Its uniform particle binding provides products with uniform pores and stable quality. * Because various plastics can be used, products exactly meeting the customer’s needs in terms of heat resistance, chemical stability, etc. are available. * The integrated production system provides a variety of shapes and dimensions according to the customer’s requirements, in addition to prompt, secure delivery of products.
