Message from us

We will always be an honest company that puts customer satisfaction first.

Thank you for your interest in Dongyang Lubesil. Since our founding in 1994, we have spent more than 30 years supplying silicones to a wide range of industries.

As a partner of Dow, a global materials company, we supply silicone products for electrical and electronics, mobility (automotive electronics) and display applications, along with silicone pressure-sensitive adhesives (PSA), a key raw material for tapes and protective films, and transformer fluid for high-speed trains.

Our growth rests on the trust we have built with customers in Korea and abroad, and on steadily opening new markets. Backed by ISO 9001, ISO 14001 and ISO 45001 certification, we practice sustainable management.

We sincerely thank everyone for their continued support. With reliable supply when you need it and help finding the right product, we aim to be a partner in our customers’ growth.
