Tosaf Additive Masterbatch - Enhancing Plastic Performance

The role of an additive masterbatch is to improve the performance of plastic products. They can protect the product from light and heat degradation, improve optical properties and film product appearance, limit flammability in compliance with regulations, and enhance the processability of plastics.

Tosaf is a global leader in the development and production of additives masterbatches for the plastics industry. We maintain this position by continually learning, attending and delivering lectures at conferences and educational institutions, and participating in industry and academic consortia. By staying close not only to our clients but to their customers as well, we are able to gain a clear understanding of the challenges they face. We then apply all our knowledge, expertise and creativity to create tailored solutions that optimize the design and functionality of their products, through proof of concept and laboratory testing.
