Hostalen CRP 100 S YELLOW is a bimodal high density polyethylene compound (HDPE), yellow colored similar to RAL 1018 (Zinc yellow).
The compound contains a specially designed stabilisation package to protect against UV radiation and thermal degradation. Additionally it contains a pigment system with very high opacity, to provide colourful, bright stripes when extruded as thin layer on black pipes.
The yellow compound is typically used for the coextrusion of yellow identification stripes on black gas pipes produced from Hostalen CRP 100 BLACK or Hostalen CRP 100 RESIST CR BLACK.
Hostalen CRP 100 S YELLOW complies with the fusion compatibility requirements in EN 1555-1, and with the resistance to weathering as described in EN 1555-1, Table 2 after a cumulative radiant exposure of 7 GJ/m². This excellent resistance to weathering allows an outdoor storage of the pipes in Europe for 1-2 years depending on the region and the average yearly cumulative radiant dosage (see EN12007-2, Fig 2).
