Shaanxi Fanyang Construction Technology Co. Ltd offers two types of rubber and plastic insulation materials: insulation boards and insulation pipes.
The rubber and plastic insulation pipes are available in various diameters: ⊘25, ⊘32, ⊘40, ⊘50, ⊘60, ⊘76, ⊘89, and ⊘108 (in mm). These pipes are designed to provide efficient insulation for various applications.
The rubber and plastic insulation boards have a standard width of 1500mm and a length of 8000mm. Customization is available for non-standard shapes based on specific requirements.
The insulation materials are classified into two fire protection levels: B1 and B2. We recommend choosing the B1 level for enhanced safety.
The conventional insulation layer thickness options include 15mm, 20mm, 25mm, 30mm, 35mm, and 40mm. For thicker insulation layers (35mm and 40mm), it is advisable to consider the scope of the project, typically ranging from 2000m to 5000m.
Our products are manufactured to meet high-quality standards and are based on approved samples.
Under normal conditions, our insulation materials can be used for up to ten years without any issues. However, exposure to harsh environments, such as wind, sun, rain, or corrosive gases, may reduce the service life.
We recommend shipping the products through the designated ports, such as Tianjin Port or Qingdao Port, as specified by Party A.
