Brief Introduction:
Series of High-Temperature Resistant Rock Wool Products are the new generation rock wool products which our enterprise has developed specially for the ship application of A-60 grade fire division. The main material is basalt. They resulted from thread to fiber by means of high-speed centrifugal. Compared with the ordinary rock wool prductions,our fireproof temperature has already reached the test of the ship A-60 grade fire division.Compared with the ceramic fiber,these series hold the advantage for people to avoid the danger of absorbing the thin fiber.These products have filled the domestic gaps,and reached the international level And they have patented as well.| Item | Data | Remark | ||
