WACKER and Shanghai Wellion Silicone Material Agree on Co-Branding of Silicone Compounds

Shanghai, Jan 10, 2019

The Munich-based chemical group WACKER and Shanghai Wellion Silicone Material Factory (Wellion) have concluded an agreement on the co-branding of ready-to-use silicone compounds. Under its terms, Wellion is allowed to promote silicone compounds made from WACKER raw materials with the quality seal “Based on ELASTOSIL®” as of January 1, 2019. ELASTOSIL® has been synonymous with high-quality silicone rubber products for more than 60 years, and is now one of WACKER’s most successful brands.

Since January 1, 2019, Wellion is authorized to supply ready-to-use compounds made from WACKER silicones under the “Based on ELASTOSIL®” logo. (Photo: WACKER).

The parent company of Wellion, Sunstrong International Limited (SUNSTRONG), started to distribute WACKER silicone products in 1999 and has a close collaboration with WACKER for almost 20 years. As an affiliated production enterprise of SUNSTRONG, Wellion uses WACKER silicone rubbers to produce customized products for the local and international manufacturers in the Chinese automotive, medical, electrical and household industries.

“China is one of WACKER’s largest and most important markets. As a professional provider of technical and service oriented industry solutions, Wellion’s operation philosophy is a perfect match with WACKER’s strategy of sustainable development,” said Gary Wang, WACKER Greater China Vice President Silicones. “The “Based on ELATOSIL®” co-branding agreement will allow both parties to combine synergies, providing WACKER’s outstanding raw material to customers in the format of “ready-to-use”, and better meeting customer needs with Wellion’s timely and flexible services in the Chinese market.”

Jimmy Gu, General Manager of Wellion, called the agreement a major milestone of the company. He said, “ELASTOSIL® is a globally recognized trademark for high-quality silicone rubbers. WACKER has continuously enhanced its local innovation capability and has expanded its production capacity providing strong support to Wellion’s business development. I believe the co-branding will not only foster the customer’s trust to us, but also bring value-added products to customers in various industries with consistently reliable quality and higher cost performance.”


The name ELASTOSIL® is synonymous with a wide range of silicone products. Beside silicone rubber and silicone rubber dispersions, the brand also includes their related processing additives. Silicone rubber essentially consists of silicone polymers and fillers. The compound rubber undergoes high-temperature or room-temperature vulcanization, during which the uncured compound becomes an elastomeric rubber. Silicone rubbers are heat resistant, flexible at low temperatures, resistant to aging, and easy to process, and have good mechanical properties that remain unchanged over a wide temperature range. ELASTOSIL® silicones are used in areas such as automotive and mechanical engineering, electronics and electrics, textiles, medical articles, toys, household appliances and sports articles, as well as in the construction industry.
