LANXESS’ Modulast PUR modifier for enhanced performance and economy

International supply chains have been impaired by the Corona pandemic since 2020, and the supply bottlenecks have been further exacerbated by the effect of Russia’s war on Ukraine. Reason enough to use resources as economically as possible. The latest example from the industry: With the Modulast PUR modifier from specialty chemicals company LANXESS, the use of polyols and isocyanates can be reduced while maintaining and often improving physical properties in thermoplastic polyurethanes (TPU) and CASE (Coatings, Adhesives, Sealants, Elastomers) applications.

Highest purity and lowest OH number

Modulast PUR is a proprietary dibenzoate exhibiting the highest purity (> 98%) and lowest hydroxyl number (< 2 mg KOH/g) on the market. It offers superior color, abrasion resistance and compression set and – due to its excellent compatibility – has extremely low migration tendencies.

Savings in raw material and manufacturing costs

By adding the modifier in amounts of up to 30 wt.%, typically 20 wt.%, the consumption of tight polyols and isocyanates and thus the total raw material costs can be reduced significantly. The production process benefits from a reduced temperature range for molding/demolding leading to shorter cycle times and higher productivity.

Maintaining superior mechanical properties

The high purity of Modulast PUR and its low hydroxyl value results in more complete and efficient reactions of polyol and isocyanate, thus maintaining the superior mechanical properties of polyurethane, e.g., high load bearing capacity (compression set) and excellent strength and toughness, reducing the chance of part failure (abrasion resistance).

Modulast PUR is easy to handle due to its excellent HSE profile and the fact that no labelling is required in the US and in Canada.
