Diversity of the modular system
Levamelt® is successfully used in an extraordinarily wide range of applications. The portfolio of products offered by LANXESS to its partners in the industry is also correspondingly large.
As a result of the continuous optimization of the medium pressure method at LANXESS, the vinyl acetate (VA) content of the Levamelt® grades currently available covers the whole range from 40 to 90 percent VA. The VA content is indicated by the first two numbers of the designation. For example, Levamelt® 500 contains 50 percent vinyl acetate. The third figure identifies Levamelt® grades with particular characteristics. For example, Levamelt® 456 has a significantly higher melt flow index than Levamelt® 450 (between 15 and 35 in comparison to between 1 and 5) as a result of targeted control of the molecular weight. Products with the abbreviation VP are test products whose ultimate launch onto the market is decided in close cooperation with users after comprehensive discussions. LANXESS continuously develops the Levamelt® product portfolio in order to respond better to customer needs.
However, the user by no means has to rely just on the VA grades supplied by LANXESS in order to ensure the adhesive formula is optimally matched to his specific requirements. Since the various Levamelt® grades can generally be blended together without any problems, the developer can quickly produce adhesive formulations with polarities tailor-made to the task at hand, perform fine adjustment for the required characteristics or further expand the possible spectrum of characteristics. This means that just a few Levamelt® grades stored in the warehouse can cover an extraordinarily wide range of EVM applications, opening up a whole new world of possibilities for experts.
It is important to remember that, although Levamelt® is indeed a rubber material, it is supplied to users in exactly the same form as they are familiar with. For example, in the form of granules for plastic processors and in the form of a powder for modifying thermoplastics such as PVC. A continuous cooling chain ensures that the material is always ready for processing and arrives at the customer in optimal flowable condition.
