Company Profile

High-temperature oxidation remains a silent cost driver across lubricant and fuel-additive supply chains. Liaoning Hongyi Chemical Co., Ltd. supplies ADPA-98, an alkyl diphenylamine antioxidant positioned for that exact pain point. The China-based seller lists the product under the HONGYI brand with model number ADPA98.

Buyer-relevant seller capabilities include:

  • Product focus: lubricating oil additives, engine oil additive packages, extreme pressure and antiwear agents
  • Classification: chemical auxiliary agent for petroleum additives
  • Usage: high-temperature antioxidant

Applications

Petroleum additive buyers often need a high-temperature antioxidant that survives hot spots without sacrificing TBN retention. ADPA-98 fits as a candidate for engine oil formulations, industrial lubricating oils, and other petroleum additive systems where oxidative stability is non-negotiable.

Engine oil blenders looking to control viscosity increase and deposit formation under high-temperature operation can evaluate ADPA-98 as an antioxidant component. The product's high TBN range suggests suitability for formulations that require acid neutralization capacity.

Common sourcing contexts where this product appears:

  • Engine oil antioxidant top-treats
  • Industrial lubricant packages exposed to elevated sump temperatures
  • High-temperature antioxidant screening for petroleum additives
  • Formulations requiring low diphenylamine carryover (≤1.0 wt%)

Product Description

ADPA-98 is a transparent light-colored liquid alkyl diphenylamine antioxidant. Listed as a high-temperature agent, it targets oxidation control in petroleum additive applications.

Key listed specifications:

AttributeListed Value
AppearanceTransparent light colored liquid
Kinematic Viscosity (40°C)100–350 mm²/s
Density (20°C)945–995 kg/m³
TBN152–172 mgKOH/g
Flash Point (COC)180 min °C
Diphenylamine1.0 wt% max
Water Content0.15 wt% max

Buyer benefits to verify against your formulation:

  • High TBN range can support alkaline reserve in lubricant systems
  • Low water content helps protect against hydrolysis and additive drop-out
  • Flash point ≥180°C suggests safe handling in many blending environments
  • Low diphenylamine carryover may reduce volatility and deposit risk

Buyers evaluating ADPA-98 should compare these values against existing antioxidant baselines. Request a batch-specific certificate of analysis to confirm current viscosity, TBN, and flash point before pilot blending.
