| Hazard Information | Back Directory | [Description]
4,4′-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA,1107-00-2) is an aromatic organofluorine compound and the dianhydride of 4,4'-(hexafluorisopropylidene)bisphthalic acid (name derived from phthalic acid). It is one of the six most widely used dianhydride monomers, with good balance of mechanical properties and electrical properties, and it is also the most widely used dianhydride monomer in colorless and transparent polyimides.

Beige crystal | [Uses]
4,4'-(hexafluoroisopropylidene)diphthalic anhydride(1107-00-2) be used for the preparation of a polyimide material.
| [Application]
4,4'-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA,1107-00-2) can be used:
(1) With APAF as dianhydride monomer, it can be used to prepare thermally rearranged polybenzoxazole (TR-PBO) gas separation membranes by thermal rearrangement reaction at 450°C. The product TR-PBO membrane has excellent gas permeation selectivity and high permeability. the H2/CH4 separation performance of APAF-6FDA membrane is close to the Robertson upper limit of 2008 [5].
(2) Used as a raw material for the preparation of thermoplastic fluorinated polyimide resin.[6].
(3) Polymers for electronic materials;
(4) Polyimide materials. These materials can be used as substrates for wearable devices and as multilayer insulation materials in order to protect against space dust, cosmic rays and satellite debris[7].
| [General Description]
4,4'-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA,1107-00-2) consists of two phthalic anhydrides bridged with a perfluoroisopropyl group and is mainly used in the synthesis of polyimides. Polyimides from 6FDA are commonly used in hybrid matrix membranes. The polyimide matrix provides good dispersion of the filler and can be loaded with up to 50 wt% filler. These membranes have been used for highly selective gas separation (CO2/CH4) and solar cell encapsulation (power conversion efficiency of silicon-based solar cells increased from 14.67% to 15.64%).
| [Flammability and Explosibility]
Notclassified | [storage]
Storage precautions of hexafluoro dianhydride (6FDA) are described as follows: Store in a cool and ventilated warehouse. Keep away from fire and heat source. Packing should be sealed and out of contact with air[18]. It should be stored separately from oxidants, acids and edible chemicals, and must not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that may cause sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials. | [Advantages]
The 4,4'-(hexafluoroisopropylidene) diphthalic anhydride (6FDA,1107-00-2) monomer contains rigid benzene ring groups, and so, the resulting polymer has excellent mechanical properties. 6FDA contained a stable benzene ring and fluorine atoms. Due to the strong electronegativity of the fluorine atoms and the stability of the benzene ring, the produced polycarbonate had better thermal stability[1-2].
| [Precautions]
The storage precautions for 6FDA(1107-00-2) are as follows: The chemical must be stored in a cool and well-ventilated warehouse, away from sources of heat and fire. Proper sealing is required to prevent contact with air, and it should always be kept separate from oxidants, edible chemicals, and acids. The storage area should have explosion-proof lighting and ventilation facilities and must not allow any mechanical equipment or tools that may cause sparks to prevent accidents. Leakage emergency treatment equipment and suitable storage materials must be readily available in the storage area.
