Waterproof and oil resistant solutions for paper cups, paper holders, meal boxes, pulp, kraft paper, etc

LEMAN Polymer Technology Co., Ltd. (LEMAN) in Suzhou has a wide range of end use applications in industries such as paper molding, real estate, consumer goods, automotive, medical, and decorative materials. With a rich series of waterproof, oil resistant, and anti fouling chemical products and application evaluation systems, LEMAN has formed two major systems: water-based waterproofing agents and oil-based waterproofing agents. By actively expanding domestic and international markets, LEMAN has established a comprehensive service network covering the whole country and extending to countries and regions such as Europe, America, the Middle East, and Southeast Asia.

Oil resistant paper was invented as early as 1896, and ordinary paper cannot resist oil. In order to achieve the effect of oil prevention, certain technical means are usually used, such as super calendering to increase the density of the paper, while also coating a layer of wax (stearic acid) on the surface of the paper, and sometimes even soaking in sulfuric acid treatment to prevent the penetration of oil. But this method is not very effective, the oil will still penetrate.

3M Company is a pioneer in the development of fluorine based paper oil protectants. As early as the 1980s, 3M developed paper oil protectants and introduced them to the market based on completely different technological principles. Fully utilizing the fluorine element can reduce the surface tension of paper, reducing it to around 20 and giving it the ability to resist oil and grease.

Unlike 3M’s ECF process, fluorine chemical companies such as Dupont mainly use the Fluorotelomer process, which does not produce PFOS as an intermediate product. Therefore, the market subsequently entered a competitive phase.

Due to market drivers, especially concerns and related lawsuits regarding PFOA, various companies have transitioned from the first generation of carbon-8 products to carbon-6 products. Their performance has significantly decreased compared to carbon-8 products, and the market response has not been ideal. The main reason is that DuPont has gradually withdrawn from the paper oil repellent market due to the impact of the PFOA incident involving ammonium perfluorooctanoate.

In the traditional fine chemical industry, Suzhou Leman Polymer Technology Co., Ltd. is also not willing to be lonely in the field of paper waterproofing and oil prevention. In 2024, it officially launched paper molding fluorine free waterproofing and oil prevention agents FP-602, FP-E01, FP-E03, and FP-E05, which enjoy a high reputation in the market. Especially FP-E05, which is a star product in the pulp molding industry, has laid the foundation and industry standard for the development of the paper mold industry. Free of fluorine elements, in compliance with GB9685-2016, GB4806-2016, and FDA21CFR176.170 standards. It also holds a place in the paper molding market. FP-E05 is an excellent product that fills the gap in the market for fluorine free waterproofing and oil resistance.
