Product Overview
Plasticizer TBC, full name Tributyl Citrate, also known as Citroflex 4, with CAS No 77-94-1 and EINECS No 201-071-2, is a classic non-toxic citrate ester primary plasticizer derived from citric acid. TBC is the base raw material for producing acetyl tributyl citrate ATBC. It features high plasticizing efficiency and excellent compatibility with PVC, cellulose resin, PLA, PBAT and nitrocellulose. TBC effectively improves product flexibility, transparency and low-temperature toughness, suitable for environmentally sensitive formulations without phthalate restrictions. Compared with ATBC, TBC has better cost performance, while its water resistance and anti-migration performance are slightly weaker. It can be used alone or blended with ATBC to balance formulation cost and anti-extraction property. TBC is widely adopted in biodegradable plastics, cellulose coating, pharmaceutical enteric coating, soft PVC and printing ink, serving as a safe substitute for traditional phthalate plasticizers.
Physical Specs
■ Appearance: Colorless to pale yellow transparent oily liquid, nearly odorless
■ Density (20℃): 1.037 ~ 1.047 g/cm³
■ Refractive Index (25℃): 1.443 ~ 1.445

Core Advantages
■ Phthalate-free & non-toxic: Meet basic environmental requirements for eco-friendly plastic formulations
■ High plasticizing efficiency: Improve resin ductility, surface gloss and film-forming property
■ Good low-temperature flexibility: Prevent finished articles from brittle cracking under cold environment
■ Wide resin compatibility: Compatible with PVC, nitrocellulose, PLA, PBAT and synthetic rubber
■ Eco-friendly biodegradable: Suitable for compostable biodegradable plastic formulations
■ Multi-functional application: Plasticizer for plastics and film-forming auxiliary for pharmaceutical coating
■ Cost-effective citrate plasticizer, can be compounded with ATBC to optimize anti-migration performance
⚠ Important Reminder: TBC contains free hydroxyl group; water resistance and migration resistance are inferior to acetylated ATBC. Select ATBC if products require long-term contact with water or oil.
Wide Applications
■ Biodegradable Plastics: PLA, PBAT composite film, disposable tableware, compostable shopping bags
■ Cellulose Industry: Nitrocellulose lacquer, cellulose acetate film, printing ink, wood coating
■ Soft PVC Products: General non-food contact flexible PVC sheet, artificial leather, plastic hose
■ Pharmaceutical & Daily Chemical: Enteric coating raw material for oral tablets, cosmetic solvent, essence auxiliary carrier
■ Others: Synthetic rubber softener, cigarette filter tip plasticizer, solvent-based coating leveling agent

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.
