Description

TAISEI PFSA membranes are non-reinforced films which made of chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. It has high thermostability, excellent mechanical, electrochemical properties and long-term chemical stability. Because of the high chemical stability of perfluorosulfonic acid, TAISEI N series PEMs exhibit substantially lower fluoride ion release compared to other type of PEMs. They can be used in strong acid, strong alkali, strong oxidant and other harsh environments. The membrane performs as a separator and solid electrolyte in a variety of electrochemical devices that require the membrane to selectively transport cations across the device junction. The elaborately planned craftsmanship promotes their application advantages in PEMFC and VFB system.

Order and Packaging Information

Membrane dimensions are based on dry product conditioned at 23 °C and 50% Relative Humidity before cutting. The membrane's water content will affect its dimensions, and the change may not be symmetrical in the length, width, and thickness directions. In addition, certain conditioning steps performed by the customer also may affect the dimensions. Customers may wish to review the membrane treatment steps and dimensional requirements with a TAISEI technical representative before establishing membrane shipping dimensions.

Standard dry product dimensions for individual pieces include:

Width: 0.10 m (min.) to 0.6 m (max.)

Length: 0.10 m (min.) to 0.6 m (max.)

The membrane delivery package for cut pieces will depend on the size and quantity of the membrane order. Most of the membranes are shipped flat, while longer lengths of individual pieces are shipped on a roll. The membranes are protected with a soft protective film and inner packaging bag, then placed in shipping containers.

Membrane pieces or rolls can be cut into custom sizes, and special packaging provided at additional cost and/or delivery time. Please contact TAISEI customer service for details.

There is a 10m²  minimum order requirement for non-standard widths and lengths.

Recommended Storage Conditions 

Unopened packages of TAISEI PFSA membrane should be stored in the original shipping box, recommended storage conditions are:

1. Out of direct sunlight, and in a climate-controlled environment, maintained at 10 to 30℃ and 30 to 70% relative humidity

2. Before opening the package, pre-condition the membrane to the processing area temperature for 24 hours.

Note: Once opened and exposed to the environment, the membrane will equilibrate to the ambient relative humidity, and change in dimensions accordingly. Membrane order dimensions are specified and measured at 23°C and 50% Relative Humidity.

Handling Practices

Ventilation should be provided for safe handling and processing of TAISEI PFSA membrane. The amount of local exhaust necessary for processing TAISEI PFSA membrane at elevated temperatures will depend on the combined factors of membrane quantity, temperature, and exposure time.

Note: For detail safety instructions, please refer to corresponding safety data sheet.

Scrap Disposal 

Preferred disposal options are (1) recycling and (2) landfill. Incinerate only if incinerator is capable of scrubbing-out hydrogen fluoride and other acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable federal, state/provincial and local regulations.
