We are VERY happy with the results we’ve seen from your products, both from the primer adhesion side and the casting processing as a whole. We’re hoping to push Hapco material into more and more of our assemblies that require casting and grow our usage of your products across many other applications.
We’ve been using Hapflex 665 and 668 to cast patterns and core boxes since the late ’80s and man this stuff is TOUGH! It’s a bit pricier than Freeman and BJB but the quality and consistency are what keeps coming back to Hapco year after year.
We’ve been using Hapflex and Steralloy for low volume medical device manufacturing for over 40 years. The quality and consistency are second to none! I can’t say enough about their customer service either. Jennie, Fred, Dan, and Rick are all great at what they do!
HAPFLEX™ 500 SERIES
Flexible Urethane Elastomers (60-95A)
Hapflex™ 500 Series products are shock resistant and virtually unbreakable, making them perfect for permanent molds or parts that will withstand repeated abuse. A major advantage is their performance in low temperatures. These liquid rubbers have been used for casting molds, parts, seals, gaskets, pads, and coatings.
HAPFLEX™ 600 SERIES
Semi-Rigid Urethane Elastomers (50-72D)
Hapflex™ 600 series products are known for their superior impact and abrasion resistance. When post-cured, these hybrid polymers are virtually unbreakable. Living hinges, protective coverings, fixtures, forming dies, foundry patterns and core boxes are just a few examples of 600 Series applications.
HAPFLEX™ 700/800 SERIES
Hapflex™ 700 & 800 Series products are flexible and colorless, making them great for use with Hapco’s Color Dispersions. These thermoset liquid rubbers make excellent adhesives, but are commonly used to cast prototypes, colored production parts, domed labels, coatings, pads, seals and gaskets.
HAPFLEX™ 1000 SERIES
Low Durometer Urethane Elastomers (20-55A)
Hapflex™ 1000 Series products are soft, colorless, thermoset liquid rubbers. These two-component hybrid elastomers are used in industrial, electrical, and prototyping applications (bumpers, pads, gaskets, etc.) The 1000 Series can also be used to make molds for resin casting.
NOTE: These products are intended for industrial use only. Refer to the Safety Data Sheets prior to use.
