• Two fiber lengths doing two jobs. Long softwood fiber builds the load-carrying network. Short hardwood fiber flows into detail that long fiber bridges over. One material, both properties.
• Adjustable ratio. A deep structural part shifts the blend toward softwood. A fine-detail Type 3 part shifts toward hardwood. The specification moves with the application rather than forcing a compromise.
• Best detail reproduction in the range. Hardwood fiber at under 1.2 mm reaches into mold features that agricultural and recycled fibers cannot fill cleanly.
• Pale natural tone. Lighter than kraft and considerably lighter than recycled, which gives a clean finish without a bleaching stage.
• Chain of custody available. FSC and PEFC certification can be supplied where your customer or your reporting requires documented forest sourcing.
• Dimensional consistency. Virgin fiber with controlled composition drains predictably on the forming screen, which is what tight dimensional tolerance actually depends on.

Hardwood and softwood differ because the trees do. Softwoods such as pine and spruce have long tracheid cells that evolved to carry water up tall trunks. Hardwoods such as eucalyptus and birch have shorter vessel and fiber cells. Neither is better; they do different work, and almost every high-quality paper and molded fiber product uses both.

The cost position is at the upper end, since this is virgin fiber competing with every other use for the same wood. The argument for paying it is that a precision part in this material can often run thinner and tighter than the same part in a cheaper fiber, which recovers some of the difference.
