Hapflex™ 500 Series

HIGH PERFORMANCE HYBRID ELASTOMERIC POLYMER ALLOYS

The Hapflex™ 500 Series offers soft durometer elastomers ranging from 45 - 95 Shore A. All are relatively fast, room curing, flexible systems that can be accelerated with moderate heat for faster cycle times. Most 500 Series products are available in a slower speed (20-45 min.) when hand mixing, or a faster speed (3-6 min.) for use with Hapco’s dispensing equipment.

All Hapflex™ elastomers are medium-low viscosity, making them easy to handle and pour, yet still provide precise duplications of surface details.

In addition, the Hapflex™ elastomers are virtually shock resistant and unbreakable, making them exceptionally well suited for permanent molds or parts that will not crack or chip during use or storage. A major advantage is their performance in low temperatures.

Precision tracing patterns, instrument grips, gaskets, fixtures, and flexible parts and molds are just a few applications of the Hapflex™ 500 Series.
