Hardwire 3x2-4-12 Low Density Tape Product Information -:- For detailed product information, please contact sales. -: # **Hardwire® 3x2-4-12 Low Density Tape: Precision Surface Preparation System** ## **Product Overview** Hardwire® 3x2-4-12 Low Density Tape is an engineered abrasive tape designed for precision surface preparation and controlled material removal applications. The designation "3x2-4-12" refers to its **triple-layer construction** (3x2 indicating three-layer reinforcement with dual abrasive orientation), **4 oz/yd² (136 g/m²) low abrasive density**, and **12-inch standard working width**. This specialty tape represents the precision finishing segment of the 3x2 series, specifically engineered for applications requiring minimal substrate alteration, controlled material removal, and superior surface finish quality. Utilizing a proprietary low-density abrasive distribution pattern, this tape delivers exceptional control over surface profile development while minimizing heat generation and surface deformation. The intelligent grain spacing allows for effective swarf evacuation and reduced loading, making it ideal for finishing temperature-sensitive materials, composites, and precision components where surface integrity is paramount. --- ##
