PH-100
Butylated hydroxytoluene (BHT)
The most widely specified hindered phenol in existence. Fully characterised, food-contact-approved in many jurisdictions, and used far beyond lubricants — fuels, plastics, rubber and transformer oils all consume it.
- Physical form
- Solid
Typical values, not a specification. The binding specification is the one on the certificate of analysis issued against each batch.
- CAS number
- 128-37-0
- EC number
- 204-881-4
Grades a formulator would benchmark PH-100 against. Naming them is not a claim of equivalence — it is where to start the comparison.
Phenolic Antioxidants
Primary low-to-mid temperature radical scavenger
Hindered phenols built on the 2,6-di-tert-butylphenol motif. They donate a hydrogen atom to peroxy radicals and are the more cost-effective half of a paired antioxidant system below ~120 °C. Liquid grades matter for cold-blend and low-viscosity fluids where a solid will not dissolve without heat.
Industrial Gear Oils
Enclosed gear drives, wind turbine gearboxes and heavy industrial reducers.
Hydraulic Fluids
Anti-wear hydraulic oils, including zinc-free and fire-resistant fluids.
Metalworking Fluids
Neat cutting oils, soluble oils, semi-synthetics and forming lubricants.
Turbine & Compressor Oils
Steam, gas and hydro turbine oils, rotary and reciprocating compressor fluids.
Rust Preventives & Quenching
Slushing oils, export packaging fluids, quench oils and heat-treatment fluids.
A full technical data sheet, safety data sheet in the language of the receiving country, REACH status statement and SVHC declaration are issued with every enquiry for PH-100. Certificates of analysis accompany each consignment and retained samples are held for the full shelf life.
