800 Series - Black Organic Mold Rubber

The Contenti Company offers a range of organic mold compounds to suit every application of centrifugal rubber mold casting using tin and lead alloys.

Every organic rubber mold set consists of two 1/2" thick sections, and each section has 10 laminations. The term "durometer" used in the specification tables below refers to the relative hardness of a rubber compound when cured. The higher the durometer, the harder the rubber compound is. Variations in heat resistance from compound to compound are not significant.

In its unvulcanized form, the 800 series compound is significantly more gummy and tacky than other rubber mold compounds, making it a good choice when extensive build-up in mold preparation is required. Also used in spin casting high lead content alloys and for producing medallions and buttons.

• Durometer: 65
• Flexibility: Medium
• Tear resistance: Med-High
