Description
Dialkyl dithiophosphate (DDP) is a friction-reducing and anti-wear additive commonly used in lubricating oils. DDP is a compound composed of dialkyl dithiophosphates. The two alkyl groups attached to the phosphorodithioate can differ in length and branching.
DDP additives provide several benefits to lubricants:
- Friction reducing performance: DDP forms a protective film on the metal surface to reduce friction between moving parts. The film prevents metal-to-metal contact, helping to improve the efficiency and performance of the lubrication system.
- Anti-wear performance: DDP additive forms a protective layer on the metal surface, reducing wear and extending the service life of the equipment. This protective layer minimizes the formation of abrasive wear particles and helps prevent surface damage and component failure.
- Extreme Pressure (EP) Properties: DDP additives have EP properties, which means they can handle extreme pressure conditions where high loads and boundary lubrication exist. DDP chemically reacts with the metal surface to form a protective layer that can withstand high pressure and prevent metal-to-metal contact.
- Anti-oxidation and anti-corrosion: DDP additive helps inhibit oxidation and corrosion of lubricating oil. The phosphorodithioate component of DDP reacts with oxygen to prevent the formation of harmful oxidation by-products. This extends the life of the lubricant and protects metal surfaces from corrosion.
DDP additives are commonly used in automotive and industrial lubricants such as engine oils, gear oils, hydraulic oils and metalworking fluids. They effectively reduce friction, wear and surface damage, thereby improving the overall performance and service life of the lubrication system.

I switched to minglan chemical over a year ago and have zero regrets.

Judging from the results of using dialkyl dithiophosphate, this is a very wise shopping decision.”
