For a long time, phthalate esters are widely used plasticizers in PVC plastic, neoprene rubber and neoprene rubber, but the harm of phthalate esters to human body has been recognized by the World Health Organization. Therefore, it is necessary to seek a substitute with suitable price and excellent performance-environment-friendly rubber and plastic plasticizer.

Guangzhou Dagang Petroleum Science and Technology Co., Ltd. cooperated with Shanghai Jiaotong University to study and select a new type of environmental plasticizer which can be used to replace phthalate plasticizer. The products have been compared and used by customers, the effect is good, the performance is stable, and the products are well received by customers.

Main varieties: DY-19、DN-18、 DXN-34.

Purpose: 

1. Plasticizer for environment-friendly PVC products such as edible plastic wrap, children's toys, wires and cables. 

2. Environmental plasticizer for neoprene and neoprene rubber.

Features: This series of products are used in PVC products with good technological properties. As the first plasticizer of PVC, its mechanical properties are the same as those of DOP, and its thermal stability is better than that of DOP. Its thermal stability, migration and oil vapor resistance are better than some unleaded benzene plasticizers such as DOS and DOA, so it has a higher performance-to-price ratio. In terms of environmental performance, it conforms to the relevant regulations of EU on 17 items of phthalate esters, RoHS, Reach and PAHs, and is the preferred plasticizer for export products.

Nature: It is insoluble in water, soluble in usual polar organic solutions, and can be mixed and blended with all commonly used PVC plasticizers.
