High-temperature lubricant oxidation remains a top failure driver in engine and industrial oil systems. ADPA-98 alkyl diphenylamine antioxidant from Liaoning Hongyi Chemical targets that pain point as a high-temperature petroleum additive. Listed specs…
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:
| Attribute | Listed Value |
|---|---|
| Appearance | Transparent light colored liquid |
| Kinematic Viscosity (40°C) | 100–350 mm²/s |
| Density (20°C) | 945–995 kg/m³ |
| TBN | 152–172 mgKOH/g |
| Flash Point (COC) | 180 min °C |
| Diphenylamine | 1.0 wt% max |
| Water Content | 0.15 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.
Indicative SKU pricing is US$4.30 per selling unit; confirm packaging and quantity basis directly with the supplier.
