ADVANTAGES OF PE-Xb
While the improved maximum operating temperature is one of the initial attractions of cross-linking, there are other advantages in comparison with uncross-linked Polyethylene:
GUIDANCE OF PROCESSING
The excellent mechanical properties shown by cross-linked Polyethylene (PEX) have led to its use in the plastic pipe industry, where PE-X pipes are replacing pipes made from thermoplastic polymers, such as PP, PVC and uncross-linked PE of all types.
PE-Xb STORAGE
The storage life is six months when PE-Xb is stored in a suitable condition.
1 The package should be opened only before processing.
2 Exposure to direct sunlight must be avoided.
3 After opening the bags the product must be used up within 4-5hours.
