Our sustainably sourced softwood bleached pulp portfolio offers a wide variety of specifications with unique product attributes to serve the needs of our customers.
Matrix® Performance is fully bleached southern kraft pulp manufactured at the International Paper mill in Riegelwood, NC. The Southern pine fibers have high brightness, exceptional length and tensile strength, making them an excellent fit for the manufacturing of fiber cement and calcium silicate boards.
Matrix® Impact is a southern bleached pulp manufactured at International Paper’s Flint River Mill designed for use as reinforcement fiber in a wide range of concrete applications. Matrix Impact will accept colors and reduce shrinkage and cracking, when compared to concrete containing common polypropylene fibers. These cellulose micro-fibers create a smoother finish compared to polypropylene micro-fibers.
