Eastman TXIB Viscosity Reducer for PVC Plastisol & Medical Gloves
High-purity 2,2,4-trimethyl-1,3-pentanediol diisobutyrate (CAS 6846-50-0) designed to cut PVC plastisol viscosity while maintaining stable molding and low migration for medical and consumer goods.
Key Features
- Viscosity at 25°C: 9 cP – dramatically lowers PVC plastisol initial viscosity
- Boiling point 281°C – low volatility, stable processing
- Non-VOC, phthalate-free, REACH and RoHS compliant
- Excellent compatibility with DINCH, DOTP, ATBC and calcium-zinc stabilizers
- Used in medical gloves, catheters, toys, and artificial leather
Applications
- PVC paste resin products – medical gloves, examination gloves, catheters (Class 1-2)
- Toys, children's products, artificial leather, floor leather, wallpaper
- Injection molded pipe fittings, valves, connectors, plastic containers
- Cable sheaths and insulation layers
- PU elastomers: viscosity reduction and surface smoothness
- EVA emulsions, inks and pigments

FAQ
Q1: Can TXIB be used in medical gloves?
A1: Yes, it is suitable for Class 1-2 medical applications, including medical gloves and catheters, due to its low toxicity and phthalate-free composition.
Q2: How does TXIB reduce viscosity?
A2: TXIB acts as a viscosity reducer, significantly lowering the initial viscosity of PVC plastisols and maintaining viscosity stability during processing.
Q3: What is the shelf life of TXIB?
A3: When stored in a cool and dry place, the shelf life is at least 2 years.
Q4: Is TXIB compatible with other plasticizers?
A4: Yes, it shows excellent compatibility with DINCH, DOTP, ATBC and common PVC resins, and works synergistically with calcium-zinc stabilizers.
Q5: What packaging options are available?
A5: Standard packaging is 200 kg/drum or 20 kg/bag.
Q6: Does TXIB comply with environmental regulations?
A6: Yes, it is non-VOC, compliant with EU REACH, RoHS, and Chinese environmental regulations, and free of phthalates.
Q7: Can TXIB be used in printing inks?
A7: Yes, it improves fluidity and dispersibility, enhancing printing quality.
