Hardwire 12x-4-12 Low Density Tape Product Information -:- For detailed product information, please contact sales. -: # **Hardwire® 12x-4-12 Low Density Tape: Precision Finishing System** ## **Product Overview** Hardwire® 12x-4-12 Low Density Tape represents an advanced coated abrasive system engineered for precision surface finishing and controlled material removal applications. The "12x-4-12" designation specifies its **12-layer composite backing architecture**, **4 oz/yd² (136 g/m²) ultra-low abrasive density**, and **12-inch standard working width**. This precision tape utilizes a patented multi-layer backing system combined with a strategically sparse abrasive distribution to provide exceptional control, minimal substrate heating, and superior surface finish quality. The 12-layer backing construction delivers unprecedented flexibility and conformability while maintaining dimensional stability, making it ideal for finishing complex contours and temperature-sensitive materials. The low-density abrasive pattern (approximately 30% surface coverage) enables efficient swarf evacuation, reduced loading, and exceptional finish consistency for critical applications in aerospace, medical device, and precision manufacturing industries. --- ##
