HB-50 Polyisobutylene for Wax Modification

Polyisobutylene is mixed with various types of wax and high molecular weight polymer, and is used in a releasing agent coated on wrapping film. For example, the compound is used for a releasing agent of block cheese wrapping film. polyisobutylene contributes significantly the compound to prevent its crack for low temperature and to improve its water proof properties.

Blended parafin wax or micro-crystalline wax with isobutylene, the wax will be brought about an increase in tensile strength, and improvements of brittleness for low temperature and vapor impermeability. Especially for the wax used for frozen food packaging in particular, it provides increased softness, reduction of break due to bending and improvement of resistance to acid.
