PERFORMANCE ADVANTAGES
PEOPLE SAFE USE, TRANSPARENCY AND INFORMATION - Reduced emissions of flame retardant material during use due to incorporation into fiber
ADDRESSING MEGATRENDS AND SOCIETAL NEEDS - Contributes to saving lives and assets as a flame retardant
PLANET RAW MATERIALS AND SUSTAINABLE SOURCING - Phosphorus is on the EU list of critical raw materials, however, recycling is possible and actively investigated
- Application of flame retardant viscose enables use of renewable raw materials (cellulose from wood) for protective garments
RESOURCE EFFICIENCY AND ENVIRONMENTAL PROTECTION - Can be applied during fiber production and thus ensures increased material efficiency due to incorporation into the viscose fiber
- Reduced waste in production through high yield and recycling of raw materials
PERFORMANCE INTEGRATED SUSTAINABLE BUSINESS - Drop-in solution for viscose process
PERFORMANCE ADVANTAGES - Complies with fire safety standards such as DIN 4102-1, class B2
- Constant high quality and hydrolytic stability
- Supports the attainability of eco-labels for customer products
- Wearing comfort is improved by the application of viscose garments with Exolit 5060 PK versus other materials
- Long lasting flame retardancy effect and washing resistance
- Lower influence on whiteness of fibers and higher light stability compared to polyaramid fibers
