ISPLEN® PB-131 N5E

ISPLEN® PB-131 N5E is a block ethylene-propylene copolymer with a high molecular weight. Due to averagely good flow properties and very high mechanical properties is a suitable grade to be processed into pipes. Its very high impact strength, even at low temperatures, and stress cracking also can use in critical conditions.

ADDITIVATION
ISPLEN®PB-131 N5E contains stabilizers and additives according to the end-use of the item in order to reinforce the thermal stability. The processor may include other additives. Formulation allows polymer stability during the normal conditions of processing and use.

COLOURING
ISPLEN grades are supplied in natural colour but they can be easily coloured with pigments steady at processing temperatures, using dry -colouring or masterbatch techniques.

FOODSTUFF REGULATIONS
ISPLEN® PB-131 N5E is approved for food contact under certain legislation. For more information about specific country regulation, please, contact with our Technical Service.

ISPLEN® PB 131 N5E is a heterophasic copolymer with medium-low fluidity designed for extrusion applications.

It has good processability and high mechanical properties especially high impact strength, even at low temperatures. ISPLEN® PB 131 N5E can be easily coloured during the extrusion process using the right pigments, preferably in the form of concentrates with a higher melt flow rate than the base polymer. It has a very high impact resistance.

TYPICAL APPLICATIONS
In extrusion and blow-moulding processes, such as:

• Films and sheets with a good surface gloss and high impact resistance

• Pipes

Recommended melt temperature range from 190 to 250°C. Processing conditions should be optimised for each production line.
