Bayer strength joint tape, white, high-strength joints staggered fiber tape, there are holes and the central pre-creased, pre-caulking materials used in conjunction, so the plane gypsum board joints, yin and yang angle corner joints treatment enhance the joint strength. Tensile strength> 5000N, anti-wet strength> 1800N, were identified through the National Building Materials Bureau, and higher than the national standard value.
