Frequently Asked Questions

TBC can replace phthalate plasticizers such as DOP and DBP in some environmentally friendly flexible products, but it is generally difficult to achieve complete replacement in all applications. It is more suitable for low-odor products, food-contact materials, children's products, and other applications with higher safety requirements.

TBC is a citrate-based, non-phthalate eco-friendly plasticizer with low odor, low toxicity, and relatively low migration. It is suitable for PVC, cellulose resins, and some bio-based materials, making it commonly used in food packaging, children's toys, medical tubing, and environmentally friendly flexible products.

TBC has moderate heat resistance and is suitable for standard flexible PVC. It is not recommended for high-temperature cables or highly weather-resistant automotive interiors under continuous high-temperature conditions. TBC is better suited for conventional applications such as food packaging, toys, and stationery.

Compared with some plant ester plasticizers, TBC offers better compatibility, but slight stickiness or migration may still occur at high addition levels, under high temperature and humidity, or when formulation stability is insufficient. These issues can usually be improved by blending TBC with TOTM, DINCH, epoxy stabilizers, or polyester plasticizers.
