Aiming to create comfortable, healthy living environments
From high-rise buildings to individual residences, Sunstar offers people- and environment- friendly building construction materials. We endeavor to reduce hazardous chemical substances in developing sealants, adhesive agents and coating materials because they could pollute inner-room environments, and we also focus on the development of products with strong properties of fire-resistance and waterproofing. PENGUIN Seal is one of Sunstar's products for building construction applications that puts top priority on healthy living environments.
In addition, we are contributing to the creation of healthy home environments by means of developing new leading-edge technologies and manufacturing products with an emphasis on improving future living environments — products such as environment-friendly containers that contribute to reducing industrial waste during construction and those that help people effectively cope with "sick-house syndrome" caused by VOCs (volatile organic compounds).

To find a way to make optimal use of a bicycle's characteristics is something that only Sunstar's technology can do
Through applying our world-leading technologies cultivated for motorcycle parts and our other unique related technologies, Sunstar developed a new electric-power assist unit for “intelligent bikes.” The electric power bicycle assist unit has a sensor that measures the bicycle's speed and the working of the pedal and sends the electric-power needed for an assist to the motor.
