FlexaTram™-HMT

Hexamethylenetetramine

FlexaTram-HMT-100 and FlexaTram-HMT-200 are used to synthesize chemical compounds such as resins, plastics, personal care and rubber additives. Ascend has been producing FlexaTram-HMT for over 50 years at one of its world-class facilities in Chocolate Bayou, Texas.

Applications/uses

FlexaTram-HMT products are used as a catalyst in the synthesis of phenol, melamine and urea-formalde-hyde based resins and as a curing agent in the preparation of novolac phenolic resin systems. These resins are versatile synthetic materials with outstanding mechanical properties, bonding performance, chemical and water resistance and flame retardancy.

Phenolic systems

• Foundry resins
• Brake and clutch linings
• Abrasive products
• Non-woven textiles
• Proppant coatings

Personal care

• Cosmetics, foot cream and deodorants as an antibacterial and fungicidal agent
• Hair dye fixative as a preservative

Curing agent for rubber and epoxy

• High-temperature accelerators with medium to long curing ranges and slow curing rates, preventing early stage rubber sagging
• Secondary accelerators to control curing rates such as mercapto, sulphenamide, thiuram and dithiocarbamate

Combustion

• Fuel additive in combustible solid fuel cubes and in RDX for the explosives industry

Adhesives

• Rubber-to-fabric
• Rubber-to-metal (steel cords)

Intermediates

• Chelating agents and other agro compounds

Food additives

• Cheese preservative
• Fungicide for citrus fruits

Medical

• Methenamine mandelate and hippurate treatment of urinary tract infections

Rubber

• Dinitrosopen-tamethylene-tetramine, a blowing agent for rubber
