ARflow® 93687

Product Overview

ARflow® 93687 is a medical grade hydrophilic pressure-sensitive adhesive coated on both sides of a thin polyester film. The adhesive layer on both sides is protected by a polyester release liner.

Illustration of a layered adhesive structure with labeled components: release liner, adhesive, and carrier.

Product Applications

The typical use for this product is in applications that require a hydrophilic spacer that can be die-cut into precise channel layers and bond to top and bottom components to form a microfluidic device. The hydrophilic walls created by the adhesive provide passive movement of biological fluids from an entrance port to a detection zone.

Features and Benefits

Stable to a wide array of temperatures and humidity
Hydrophilic, pressure-sensitive, flexible tape with excellent die-cutting
Wettable to liquids such as water, urine, blood, etc.
Provides adhesion to polymer and metalized polymer surfaces
