CFCM Evonik Wynca 400October 14, 2021

The joint venture between Evonik and the Chinese company Wynca - Evonik Wynca (Zhenjiang) Silicon Material Co., Ltd. is starting-up of its new fumed silica plant. Located in the Zhenjiang New Material Industry Park in Jiangsu province, the plant is Evonik's first fumed silica production site in China. It will produce fumed silica marketed under the brand name AEROSIL. More than 150 participants, including employees from Evonik and Wynca, partners, government and media representatives, attended the opening ceremony.

Fumed silica is an important functional material. With features such as thickening, thixotropy, anti-precipitation, and matting, it has been widely applied in industrial applications such as silicones, coatings, adhesives, and sealants. The demands for fumed silica in the Chinese market is growing steadily. Evonik is a leading global supplier of silica with its products widely used in many high-growth markets.

The joint venture will combine Evonik's product technology with Wynca’s silicone industry chain, producing high-value fumed silica products through the comprehensive use of monomer by-products, methyltrichlorosilane and chlorosilane from Wynca. Meanwhile, the by-product hydrochloric acid will also be fully utilized as a raw material for Wynca Zhenjiang Site. This production loop is expected to contribute to synergies among silicone monomer, chlorosilane and fumed silica production, and ultimately to a circular economy. With this new joint venture, Evonik is well positioned to build a complete global supply chain of fumed silica for customers in China and Asia.

Dr. Claudine Mollenkopf, head of Evonik Silica business line said: “I am excited to witness the cooperation between Evonik and the Chinese partner Wynca. The joint venture will be a strong complement to Evonik’s global presence in fumed silica. We expect win-win results through leveraging the expertise of both parties in silicon materials.”

“The partnership allows both sides to realize integration and complementarity in the supply chain of fumed silica and the recycling of materials. The improved value chain will enable us to deliver premium services and products to customers in China and Asia,” said Jianhua Wu, chairman of the Wynca Group.

Fuliang Xia, president of Evonik Greater China, said in his speech at the opening ceremony: “Since the plant broke ground in December 2019, we’ve completed the construction work on schedule with high quality and safety standards. We live up to our commitment to the customers. Evonik continues to develop its global footprint and focus on providing local customers with tailor-made products and services. We are also looking forward to joining forces with Wynca, our strong partner in China, to drive the growth in the Chinese market.”

New Bacharach Sling Psychrometer


CFCM slingpsychrometer 400Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.

As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.

The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart. Gardco.com
