Research and development/Creation of Lonseal technology for comfortable future/It has been more than half a century since Lonseal succeeded in manufacturing vinyl chloride products for the first time in Japan. We have been developing new technology focusing on the needs of the current times  so that everyone can live comfortably and healthy based on our environment-friendly vinyl chloride products. We will introduce the research and development of Lonseal to create technology.

Research and development by Lonseal

We aim to create pleasant living spaces with high quality and technology, and contribute to society through manufacturing activities that are gentle to people and the environment. – Based on our philosophy, research and development of Lonseal is focusing its effort on growing the existing business fields and creating new products, technologies, and business by the innovative technology development. This combines plastic compounding and processing of the basic technology with the core technology.
To make timely and optimal proposals in response to recent rapid market changes and global competition, we are carrying out speedy research and development by deeper collaborations between the research and development section and business and sales sections.
