Hapflex™ 700/800 Series

HIGH PERFORMANCE HYBRID ELASTOMERIC POLYMER ALLOYS

Hapflex™ 700/800 products are colorless, high strength elastomers available in hardnesses ranging from 65A to 72D. Hapflex™ 700/800 products exhibit high tensile strength, high tear strength, and excellent elongation. All Hapflex™ 700/800 products cure at room temperature and can be accelerated with heat.

Another key attribute of this series is that the base color of all components is colorless with no amber or yellow tint. These products are available in a 20 minute and 5 minute gel time for hand mixing or use with equipment. The fast and regular versions can be blended to customize the gel time without the addition of heat. All 700/800 Series products are available in their natural colorless state or black.

Hapflex™ 700/800 Series can be used for mechanical, electrical, and Liquid Molding™ applications. In addition, these materials show superior water immersion properties and superior adhesion when used in combination with Hapco's Primer 200.

NOTE: These products may have a negative reaction to silicone based rubbers and release agents. For best results, use Hapco's Hapsil 360 silcone rubber without any release agent. Contact a Hapco representative for more information.
