We have about 10 years experience in solid surface product, try using a lot of different materials, we have been committed to solve the problem of yellowing of these products, and get good results. We purchased acrylic resin at Lucite International (China) Chemical Industry Co., Ltd from year 2008 to now. That's why our prices are higher than others. We have many clients who we are cooperating with for 6-7 years, but haven't received complaint of yellowing problem. And some of our clients, once they had purchased some cheap solid surface products from other factory, and then they found out the items would turn yellow within one year of usage, so they come to our factory and become our clients.
