Absorbent Product Services (APS)
Who We Are
Absorbent Product Services (APS) is an independent laboratory specializing in superabsorbent polymer (SAP) performance testing, founded on 25 years of experience in the superabsorbent industry.
We operate independently of raw material suppliers and manufacturers, providing objective testing data to support material qualification, supplier comparison, and product development.
Our work helps product teams evaluate polymer performance, benchmark materials, and understand how SAP behaves within finished absorbent systems.
APS testing is built around:
-
Industry-standard SAP test methods (NWSP / EDANA / ISO)
-
Firsthand experience bridging SAP supplier data and real-world absorbent product performance
-
Clear, comparative reporting designed for material evaluation and qualification
Testing Standards & Methods
APS testing programs are aligned with recognized industry methods used for evaluating superabsorbent polymer performance. These include established NWSP, EDANA, and ISO test procedures commonly used for material qualification and comparative evaluation.
Testing packages are structured to provide clear, repeatable performance data that supports product development, supplier comparison, and material selection.
Our Background
For nearly 20 years, the work was straightforward. Make SAP perform in customer applications, or understand why it wouldn't. That experience now drives every testing program at APS.
Operating independently means no manufacturer affiliation, no commercial interest in the outcome, and no constraints on what the data shows. The result is objective performance evaluation that stands on its own.
That background shapes how every testing program is approached, from method selection to how results are interpreted in the context of real application performance.
Industries We Serve
APS supports clients across industries where superabsorbent polymers play an important role in product performance, including companies developing bio-based and novel absorbent materials. Our testing helps teams evaluate SAP materials, compare suppliers, and better understand performance within finished products.
Industries served include:
-

Commitment to Confidentiality
APS understands the importance of protecting client materials, data, and intellectual property. All testing programs are handled with strict confidentiality from sample receipt through final reporting.
A standard laboratory-specific NDA is available for all testing programs and serves as the default agreement. Client-provided agreements may be considered depending on scope and terms.
Our goal is to provide a trusted, independent environment where clients can evaluate materials with confidence.
