WT1 is an eco-friendly, non-toxic primary plasticizer based on citrate esters. It serves as an effective substitute for traditional phthalate plasticizers (such as DOP and DBP) and terephthalate plasticizers (like DOTP). The product is primarily used in eco-friendly PVC applications, including disposable gloves, work gloves, children's toys, yoga balls, flooring, calendered films, hoses, stationery, and footwear materials. Additionally, WT1 exhibits excellent compatibility with nitrile rubber, making it suitable for use in nitrile rubber compounds and nitrile-modified PVC products. It also functions as a plasticizing and softening agent in material systems such as water-based styrene-acrylic coatings, pure acrylic coatings, epoxy resins, and acrylic resins.

1. Excellent Flexibility: WT1 offers high plasticizing efficiency, imparting good flexibility to PVC products. To achieve the same hardness (e.g., 65 Shore A), the dosage of WT1 can be reduced by 5–10% compared to DOP.
2. Superior Low-Temperature Performance: WT1 exhibits excellent low-temperature resistance, enabling PVC products to maintain good flexibility and performance in cold environments.
3. Efficient Low-Temperature Plasticization: Due to its high plasticizing efficiency, WT1 lowers the plasticization temperature during PVC processing, thereby reducing energy consumption and increasing production efficiency.
4. Good Transparency: WT1 is highly compatible with PVC resin, effectively enhancing the transparency of PVC products.
