CRP 100
Hostalen CRP 100 RESIST CR black is a high density polyethylene (HDPE), black coloured similar RAL 9004
with high melt viscosity for extrusion, injection and compression moulding. The product is classified as PE 100-
RC and provides a very good long term hydrostatic strength. Especially developed for non-conventional pipe
installation methods the product has a superior resistance to slow crack growth. It fulfils the material
requirements of PAS 1075:2009-04.

Storage:
The resin is packed in 25 kg bags, octabins or bulk containers protecting it from contamination. If it is stored
under certain conditions, i. e. if there are large fluctuations in ambient temperature and the atmospheric humidity is high, moisture may condense inside the packaging. Under these circumstances, it is recommended to dry the resin before use. Unfavorable storage conditions may also intensify the resin’s slight characteristic odor.
Resin should be protected from direct sunlight, temperatures above 40°C and high atmospheric humidity during storage. Higher storage temperatures may reduce the storage time.
