IR 67 is a masterbatch containing a 67 % concentration of finely dispersed infrared absorbing mineral additives in LDPE. It is used as a heat-retaining masterbatch for greenhouse tunnels. IR 67 gives improved thermal properties while maintaining a high level of film transparency.
It is compatible with polyolefines like LDPE, LLDPE or EVA.
It contains an especially very low amount of iron oxide.
