Advantage 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.
1.reduced deformation under load(creep)
2.improved ageing resistance
3.improved chemical resistance
4.improved abrasion resistance
5.improved impact strength
6.reduced rapid crack propagation (RCP), even at low temperatures
7.improved environmental stress crack resistance (ESCR)
8.outstanding resistance to slow-crack growth

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.


Suggestion for the best extrusive situation.

1.Predry the catalyst master batch and color master batch at a temperature of 80-90 for 2 hours
2.Reasonable design head and die to obtain a streamline production
3.When the machine is restarted after blocking 10-15min,it must be purged by HDPE(MF1:0.3g/min)
4.It is better to use the material without broken bags

PE-Xb storage
1.The storage life is six months if Suntown PE-Xb can be stored in a suitable condition
2.The package should be opened only before processing
3.Exposure to direct sunlight must be avoided
4.After opening the bags, the product must be used up within 4-5hours

PE-Xb packing
Graft Polymer: al-plastics and intertexture bags containing 25kg (95%A (Silane grafted ethylene polymer) 5% B (catalyst masterbatch) sealed under vacuum.
