Evonik P84® HT
Evonik P84® HT is a polyimide-based fiber with textile characteristics. It has a wide range of operating temperatures, from cryogenic applications to high-temperature applications. The fiber's thermal stability is based on its aromatic backbone. Despite being halogen-free, it has a high Limiting Oxygen Index (LOI) of 38%, making it non-flammable.

- Product Characteristic
The innovative P84® HT fibre is a non- melting polyimide based fibre with an exceptional thermal stability, based on the unique multilobal cross section & the aromatic backbone of the polymer. Additionally, with a remarkable LOI of 38%, these halogen-free fibres are classified as non-flammable, making them the perfect choice for applications where safety is a top priority. P84® HT's unique shape makes it possible for your next-to-skin protective clothing to assure full-battle protection by providing an excellent barrier layer that fends off those harmful particles while maximizing air flow at the same time. P84® HT multilobal shape; Unique irregular cross section for excellent thermal insulation; Soft-touch; Non-melting
