How to Read The UN Rating Codes

Posted on | by cpowell

Developed as a set of standards, by the United Nations, Un ratings are essential for shipping or storing hazardous materials. The UN Rating is a series of number and letter codes that show what a container is regulated to handle. They determine this through a series of tests that all containers must undergo if they are to be UN Rated. Current UN Regulations are enforced by the D.O.T. It is up to the filler of the product to determine what UN Rating they need.

QUORAL® BARRIER RESIN (BR)

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
