After Momentive Advanced Materials Group (formerly GE Advanced Materials Group) and the Ministry of Agriculture signed a memorandum of cooperation on pesticide spraying technology in November 2005, the group, in collaboration with the Ministry and its affiliated agricultural technology promotion centers, initiated a series of pilot tests, training sessions, and promotional activities across key agricultural regions nationwide. This partnership aimed to enhance the efficiency and effectiveness of pesticide application through advanced technological solutions.
Momentive's product line includes silicone-based surfactants that significantly improve the performance of agrochemicals. Compared to traditional surfactants, these products offer superior adhesion to plant surfaces, enhanced spreading, and improved wetting properties. They allow pesticides to penetrate more effectively through plant pores and resist being washed away by rain. As a result, only a smaller quantity of pesticide is needed to achieve optimal coverage and pest control, which also enhances the reliability of the treatment.
According to Xia Jingyuan, director of the National Agricultural Technology Extension Service Center under the Ministry of Agriculture, the use of this innovative silicone technology can boost pesticide efficiency by up to 30%. This means that farmers can reduce pesticide usage by 20% to 30% per acre while maintaining or even improving crop protection outcomes.
Experts from the Ministry of Agriculture also highlighted that this silicone-based innovation not only conserves water but also minimizes environmental damage caused by excessive pesticide use. Based on the national cultivated area of 1.8 million mu, the technology can save 75 kilograms of water per acre annually—representing a 50% reduction, with five applications per year. If fully implemented, it could save at least 135 million tons of spray water and pesticide nationwide. Additionally, reducing pesticide use by 30% would equate to saving approximately 48,000 tons of chemical inputs annually.
This collaboration marks a significant step forward in sustainable agriculture, demonstrating how cutting-edge materials science can support both environmental stewardship and agricultural productivity.
DINP
The Plasticizer DINP is di isononyl phthalate (DINP), which is formed by esterification of phthalic anhydride and isononyl alcohol. DINP is a general plasticizer. One of the main raw materials of DINP, isononanol (INA)
Compared with DOP, DINP has a larger molecular weight and a longer carbon chain. Therefore, it has better aging performance, anti migration performance, anti extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP was slightly worse than that of DOP. It is generally believed that DINP is more environmentally friendly than DOP.
DINP, as a main plasticizer, is widely used in various soft PVC products. Such as wire and cable, film, PVC leather, PVC floor leather, toys, shoes, edge banding, sheath, wig, tablecloth, etc. DINP also has a small number of applications in some rubber products and coatings.
DINP is an oily liquid under normal conditions and is insoluble in water. Generally, it is transported by tank trucks, and small batches are transported by iron drums or special plastic drums.
Advantages of DINP plasticizers:
1. Stronger anti-aging ability, can prolong product life
2. Plastics are easier to coat, spray and dip
3. Higher durability, more resistant to outdoor low temperature
4. Compatible with auxiliary plasticizers, thus further reducing costs
5. Low volatility, which helps to reduce volatile in the process and improve working conditions
6. Lower density, lower energy consumption and higher extrusion output than DOP
