Product Overview
Antioxidant 2246 with CAS number 119-47-1, also abbreviated as AO2246 or MPB, is a classic bisphenol-type hindered phenolic primary antioxidant specially developed for rubber, latex and general polymer materials. As an efficient free radical scavenger, Antioxidant 2246 effectively terminates thermal oxidative chain reactions, delivering outstanding anti-heat aging and anti-ozone cracking effects for rubber products. It features low volatility during high-temperature vulcanization and extrusion, good miscibility with natural rubber, SBR, NBR, EPDM and polyolefins without blooming or surface precipitation. Compared with single phenolic antioxidants, it performs better in dynamic rubber parts that bear repeated bending and long-term outdoor exposure. It can be used independently or synergistically matched with secondary phosphite Antioxidant 168 to build composite stabilizer systems for PP, PE, ABS, masterbatch and hot melt adhesives. Antioxidant 2246 is non-toxic, non-polluting and low-discoloration, a cost-effective universal anti-aging additive for rubber factories and plastic compounding manufacturers worldwide.

Frequently Asked Questions(FAQ)
1. Q: What would you do to guarantee the product quality?
To fully guarantee stable and reliable product quality, we implement full-process control covering Quality, Health, Safety and Environment (QHSE) with systematic measures,conduct multi-stage product testing with full batch traceability, adopt strict health & environmental control to avoid product contamination, carry out regular QHSE audits and continuous system optimization, plus standardized storage and logistics management. Every link follows unified QHSE rules to eliminate quality risks fundamentally.
2. Q:Can you provide COA / MSDS /TDS before order?
Yes, we can provide complete COA, MSDS /TDS documents for your reference prior to placing orders. Please advise the exact product grade and quantity you intend to purchase, and we will send you the latest updated versions of these technical documents promptly by email. All files are issued in accordance with international QHSE standards,for your customs clearance, laboratory testing and internal risk assessment.
3. Q: What about your price?
We offer flexible and favorable prices for bulk orders. To provide an accurate best quotation,
kindly advise: (1)Required product grade (2)Order quantity (3)Preferred trade term (FOB / CIF) (4)Destination port
Meanwhile, we can supply complete TDS, SDS and COA for your reference before order confirmation. We believe this is an effective way to build long – term business with our customers and earn good reputation.
4. Q: What payment terms do you accept?
We support multiple flexible payment terms to meet different cooperation demands:
(1)T/T (Telegraphic Transfer): 30% deposit in advance, 70% balance against copy of Bill of Lading; full T/T in advance for small trial orders.
(2)Irrevocable Letter of Credit at sight (L/C at sight): Acceptable for large bulk orders, issued by reputable international banks.
(3)Negotiable payment terms can be discussed for long-term cooperative clients with stable monthly orders.
5. Q:What about the order lead time?
Our standard production lead time is 10–15 working days .
(1)For T/T payment: 30% deposit by T/T in advance, balance against scanned BL copy. After your deposit arrives, we will schedule raw material procurement and production immediately within the 10–15 day cycle. This mode safeguards mutual capital safety: the deposit locks exclusive production capacity for you, while you only settle the rest after seeing loading evidence.
(2)For L/C payment: We accept irrevocable sight L/C issued by first-class international banks. The 10–15 working days lead time will start running after we receive and verify the operative L/C text without unachievable clauses. A formal L/C serves as bank credit guarantee for both parties, eliminating default risks effectively. We will review L/C terms thoroughly before production to avoid discrepancies and potential financial losses for both sides.
6. Q:Which ports can you ship from?
We support shipment from Qingdao Port and Tianjin Port of China; you can choose the loading port as per your actual demand.
7. Q:Can you arrange thirty party inspection during loading?
Yes, we fully support third-party inspection during container loading. You can appoint your designated inspection agency to attend the whole loading process at our warehouse. Our QHSE team will coordinate all preparation work in advance, including raw batch COA checking, product appearance verification, weight tally, packing integrity supervision and sealing recording.
8. Q:Do you accept OEM packaging (private label)?
Yes, we support OEM & private label packaging service for our products. You can provide your customized brand logo, label design, bag/barrel printing artwork and customized packaging specifications.
