Materials Testing - Pulp Testing

The final quality of paper products is influenced by the properties of raw materials, fibers, and process conditions. In today’s market, fiber resources are continually changing, and new fiber types and combinations are being developed. The Process Development Center can support your efforts to maintain product quality and performance. Our wet labs and controlled environmental testing room provide many tests to characterize the properties of pulp and fibrous raw materials for papermaking. Our staff is available to serve your needs, with tests ranging from standard to customized.

Pulp & Fiber Analytical Equipment


The University of Maine has broad range of equipment for evaluation of different kinds of raw material for pulp and paper production. In chips for pulp production, we can analyze for important properties such as:

A pulp yield measurement method has been developed at the University of Maine. Samples are collected at the mill, then analyzed for cellulose, hemicellulose, lignin content and cellulose degree of polymerization. The total yield for the mill operation is then calculated. A validated data bank for estimating pulp yield using this technique can be used to estimate the yield of a variety of wood species and various pulps, provided the wood furnish composition is known.
