QUORAL BARRIER RESIN (BR)

+ Quoral BR is BP Polymer's unique and proprietary barrier resin additive for high density polyethylene (HDPE) that utilizes laminate technology thereby creating 'Baritainers' (cf. Technology).

+ Quoral BR is based on engineered grades of Polyamide (PA) 6.

+ Customized and proprietary manufacturing processing techniques are necessary to ensure optimal barrier performance in BPI's Baritainers (cf. Products).

+ The result is a laminar microstructure in which the Quoral BR forms stacks of large overlapping platelets or discontinuous layers within the Baritainer wall which limit hydrocarbon permeation.   By creating a 'tortuous path' for large chain molecules, hydrocarbons attempting to diffuse through the HDPE walls into the atmosphere are stopped. 

+ Standard Grades:
    * Quoral BR 70 = for containers < 5 Liters.
     * Quoral BR 50 = for containers > 5 Liters.

+ With the same processing conditions, the amount of barrier can be adapted by the amount of Quoral BR added.





    
    

+ In comparison with HDPE, Quoral is:
    * Vs. Hydrocarbons (solvents) 100 times more efficacious.
     * Excellent aroma barrier.
     * 2x to 5x improvement in O2 barrier performance.

+ Properties of HDPE remain unchanged:
    * Printability
    * Mechanical Properties
    * Colorants
    * UV Additive
    * Seal Properties
    * Anti-Static Additive
    * Fire Retardant Additive
    * Recyclability
