Cost-Effectiveness of Zinc Neodecanoate

One of the most compelling reasons to use zinc neodecanoate in foam manufacturing is its cost-effectiveness. While it may not be the cheapest additive on the market, its efficiency and versatility make it a cost-effective choice for many manufacturers. Let’s take a closer look at how zinc neodecanoate can help reduce costs in foam production.

Lower Material Costs

Zinc neodecanoate is highly efficient, meaning that manufacturers can use less of it compared to other additives while still achieving the desired results. This can lead to significant savings on raw material costs. For example, studies have shown that using zinc neodecanoate as a catalyst in PU foam production can reduce the amount of catalyst needed by up to 30% compared to traditional tin-based catalysts (Source: Journal of Applied Polymer Science, 2018).

Reduced Energy Consumption

By accelerating the curing and expansion processes, zinc neodecanoate can help reduce the amount of energy required to produce foams. This is particularly important for manufacturers who are looking to reduce their carbon footprint and lower operating costs. In one study, the use of zinc neodecanoate in PE foam production resulted in a 15% reduction in energy consumption compared to traditional cross-linking agents (Source: Polymer Engineering & Science, 2019).
