Resinex RX 137

Acerca de este producto

Overview:

RX 137 NATURAL is the same Dowlex XZ89342.00, only the label on the bags is different.

When we use Dowlex XZ89342.00 or XZ89342.10 to make colours, black or special effects, the resulting product is named:
RX 137 "colour" xxxx (xxxx is a unique 4 digit number for that colour).

There are many versions of RX 137 available, Natural, Black, Colour compounds, Colour dry-blends, Special Effects, etc
Some grades have special approvals e.g. Natural and Black have WRAS potable water approval
Please check the documents to see which grade has what aproval.

Applications / Grade Selection:

As with all rotomoulding applications, segmentation by application type is far too specific since the range of grades is so limited.
We can divide the whole of the roto market into 3 segments:

1. Large Tanks
2. Specialities e.g. Boats and Kayaks, Flare Retardant, Conductives, Foamm etc
3. Everything else

For large tanks, a typical tank grade should be used e.g. Dowlex NG2432UE or XZ89342.00
For everything else, either Dowlex 2629UE or Dowlex 2631UE should be used.
2629 has lower flow so will be tougher, and 2631 will allow more complex shapes to be moulded.

The starting point is also to counter-type what is currently being used.
