Cariflex® IR0307 K

About
Cariflex IR0307 KU polymer is a solution polymerised polyisoprene with a high cis-1,4 content. It has a high molecular weight as indicated by its Logarithmic Inherent Viscosity (LIV) value of 6.80 dl/g. It is supplied from North America in the physical form identified below. Cariflex IR0307 KU – supplied as white/transparent solid bale. A non-staining stabilizer is added at the typical value of 0.15%. Cariflex IR0307 KU polymer is manufactured to the highest standards but special requirements apply to certain sensitive applications such as food contact and pharmaceuticals. Reference should always be made to local legislation regulating these applications. Cariflex IR0307 KU Polymer is used as a replacement for natural rubber in a wide range of compounds, offering advantages of light color, uniformity and low levels of impurities. Its good flow characteristics produce improvements in mixing and molding behavior. It is used for food and pharmaceutical packaging and seals, baby bottle teats and health care, adhesives, chemical derivatives of rubbers and very light colored or transparent articles..&&
