This property is crucial for ensuring the longevity and durability of the putty application.

High viscosity HPMC is a modified cellulose compound that possesses a higher molecular weight, resulting in increased viscosity levels compared to standard grades. This elevated viscosity is a result of the hydroxypropyl and methyl substitutions on the cellulose backbone, which allow for improved water retention and gel formation. The thickening properties of high viscosity HPMC are particularly valued in formulations where a significant level of viscosity is required, such as in pharmaceuticals, cosmetics, food products, and construction materials.

There are a few blogs and sites pushing scare stories regarding the heavy metals found in HPMC. The heavy metals present in our HPMC are tested and certified at a level of under 10 parts per million. This is significantly below the threshold of what might be considered unsafe for human consumption. Again, it's worth noting that heavy metals are all around us and when consumed in small doses, are perfectly safe - our bodies naturally filter them out. They are found in fish, greens, brown rice and more. To clarify, we are not saying that the consumption of heavy metals is a particularly good thing, just that any form of panic or hysteria regarding the consumption of minuscule amounts of them is not helpful. For example - there is more mercury in fresh tuna than there is in HPMC. That is the very same tuna that is prized in Japanese cuisine - a country which had the second highest life expectancy in the world in 2018.
