Plastic Coextrusion (Double Seal) New Products

A new plastic steel product with advanced and practical properties, plastic co-extrusion (double seal), was recently successfully developed in Changde City, Shanxi Province, Zhongde Plastic Steel Profile Co., Ltd., and the integrated production of sealant strips and profiles has been significantly improved. The watertightness, airtightness, and permeability of the plastic windows overcome the defects of the past, such as shrinkage and lax joints, in the production process of plastic steel doors and windows. This product not only saves assembly time and time for plastic window assembly companies, but also reduces costs and greatly increases production efficiency.
