General description
Similar to montmorillonite, halloysite consists of two layers of aluminosilicate in 1:1 Al:Si ratio. Significant improvements in thermal, mechanical properties have been reported on addition of halloysite nanotubes in polymer composites.
Application
Isotactic propylene-halloysite nanocomposites.
Alloy composites by electroless/ autocatalytic deposition.
Poly(butylene terephthalate) (PBT) composites.
Zinc–halloysite nanotube (HNT) composite coatings.
Halloysite nanotube–hydroxyapatite–hyaluronic acid films.
Halloysite combined with polyamide, polypropylene, poly(ε-caprolactone) and fluroelastomers.
Its tube like morphology, high aspect ratio, and low percolation enables interesting applications as reinforcements in nanocomposites.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
