Calandering is a process in which polymers are passed through several pairs of heated rolls to produce (semi) finished sheet. Heat and shear energy is induced into the polymer to impart the required rheological, mechanical and optical properties during and after processing.
Benefits and Applications
Calandering is used to produce building and construction applications, industrial membranes, flexible packaging and other durable items.
Properties
LyondellBasell ‘s Catalloy process resins (Adflex, Hifax and Softell), with their broad range of properties and performance attributes, are selected by customers for calendaring applications that require:
- Excellent flexibility
- Good temperature resistance
- No plasticizers
- P-PVC replacement, offering good cost/performance balance
Single membranes as well as laminates of multilayer sheets can be produced using this process technology. Typically, soft sheets with anisotropic properties and wall thicknesses of ≥ 0.6 mm are produced using calandering technology.
