What is it?

The Natural and Renewable Composites from Interfacial Solutions are a variety of compounds that include fibers from natural and renewable resources and various product waste streams. The product line includes bamboo, rice hulls, shredded U.S. currency, cellulose from a paper mill, glass fiber, and many more. The fibers can be compounded into a range of polymers, both virgin and recycled, to give the customer a custom blend. In addition to the commercial grades listed here, we are always finding new fibers to give our customers the properties and look they desire. Please feel free to contact us with any questions or visit our website to see our new deTerra® line of biobased polymers.

Xusto™ MR

Moisture Resistant Product

One of the most common natural fiber materials used in the Xusto™ product line is wood fiber as the product is low in cost and easy to compound into commodity plastics such as polypropylene (PP) and polyethylene (PE). The resulting product offers good properties and a “green” message since the material is typically sourced from the waste streams of the wood products industry. However, one of the shortcomings of wood plastic composites is that the fiber is hydroscopic and can absorb a considerable amount of moisture over time, causing the fibers to swell, thus negatively affecting the appearance, feel and texture of the finished part.

Interfacial Solutions has developed a solution to this problem with its new line of Xusto™ MR natural fiber compounds. These composites offer markedly improved moisture resistance when compared to conventional natural fiber composites. Xusto™ MR composites have been formulated using a proprietary additive technology that dramatically reduces moisture uptake of the natural fiber in the composite. The result is that products made using Xusto™ MR have less color fade and surface roughness than is traditionally witnessed in conventional wood plastic composites.

Although the primary focus of work on this product line has been with wood fibers, additional moisture resistant grades have also been developed for compounds using many other natural fibers including agrofibers, such as rice hulls.
