Honestly, we started to think of sustainability regarding company development since 2000s. The products of Green Sun series were the solution of the durable polymers (rubbers or plastics). The recycle materials can be utilized as a brand-new building material. The R&D team tried very hard to develop a technique for put HDPE and Rubbers together with physical interaction. In addition, we attended many social activities, such as blood donation, and traffic products donation. The fix ratio of profit was donated to charity organization. Saving and protecting human life is not only the purpose of our products, but also the soul of our organization culture.
