HEXAMETHYLENETETRAMINE, also known as 1,3,5,7-tetraazatricyclo[18.104.22.168,7]decane, is a chemical compound used as an intermediate in the production of polyamides and polyimides. It is also used as an accelerator for curing epoxy resins and as a corrosion inhibitor. Common uses for hexamethylenetetramine include the manufacture of coatings, adhesives, sealants, and fuel additives.
When rubber is exposed to hexamethylenetetramine, the chemical can cause the rubber to become brittle, reducing its flexibility and increasing the risk of damage from fatigue and wear. The chemical can also cause the rubber to become discolored and emit an unpleasant odor. Additionally, the chemical can cause the rubber to become more prone to cracking, tearing, and other forms of damage.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
