Pel-Plug TR30
A clean, virtually odorless and easy to handle Bentonite pellet which combines the high quality yield of western Bentonite with a biodegradable nonsticking coating.
The coating, developed by PDSCo, allows the pellets to be poured through standing water without sticking together, eliminating voids and bridging. Pel-Plug TR30 has the same ability to absorb water and maintain the 8-12 times expansion pattern that has been typical of the regular Pel-Plug Bentonite pellet. Pellets should be allowed to hydrate for at least 2 to 3 hours depending on water quality.

WHAT IS BENTONITE?​
​Bentonite is an 
absorbent 

aluminium phyllosilicate clay consisting mostly of montmorillonite. It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale 

near Rock River, Wyoming. ​The different types of bentonite are each named after the respective dominant element, such as

potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite. In stratigraphy and 

tephrochronology, completely
devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite. In addition to 
montmorillonite and illite another common clay species that is sometimes dominant is kaolinite. Kaolinite-dominated clays are commonly referred to as tonsteins and are typically associated with coal.

WHAT IS SILICA SAND


Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules.

Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday items such as glass, construction materials, personal care products, electronics, and even renewable materials.

Industrial sand is a term normally applied to high purity silica sand products with closely controlled sizing. It is a more precise product than common concrete and asphalt gravels.
