Flexible & Rigid Dielectric Compounds (25A-95D)

Di-Pak™  consists of flexible and rigid, production grade, dielectric polyurethanes and epoxies for potting, encapsulating, insulating, coating, and much more. Di-Pak™ includes opaque and translucent formulations, as well as various gel times to match your application requirements.


Flexible & Rigid Thermoset Compounds (53A-85D)

Filter-bond™ is a series of thermoset potting compounds used for potting and pre-potting applications by some of the industry’s largest filter manufacturers.


Flexible, Semi-Rigid, & Rigid Elastomers (25A-72D)

Hapflex™ is easily Hapco’s most versatile line of thermoset materials. With a wide range of gel times, durometers, and colors to choose from, these high quality thermoset resins have been used for casting molds, parts, seals, gaskets, pads, linings, coatings, and much more.


Non-Inhibiting Silicone Rubber (35A)

Hapsil™ 360 is a high tear strength, tin-catalyzed RTV-2 silicone rubber. Hapsil™ 360 works well with clear and colorless casting resins that typically exhibit a sticky, uncured surface when cast against most silicones. It is easy to mix and de-gas, and cures with minimal shrinkage.


Food Grade Polyurethanes & Epoxies (25A-85D)

Food mashers, sugar and chocolate molds, dough rollers, pill chutes, filling nozzles, and sorting channels are a few examples of components that can be made from Steralloy™ products.
