gamma-butylene (GBL) is a high-polar, low-predictive, transparent, non-chromosomal liquid. It plays a central role in the chemical industry as an outstanding and environmentally friendly mass inert solvent. GBL is not only equipped with excellent solubility, which is fully soluble with water and most organic solvents, but also because of its high quality and boiling point, it is the preferred medium in many high-precision processes.
The company ' s electro-grade GBL is equipped with a very low metal ion to the PPB level and with a very low moisture feature. In the electronics industry, the GBL is equipped with an excellent electrochemical stability and high-media constant, which becomesHigh-performance electrolyte solvents, which are indispensable for the production of pyrolytic capacitors, can increase the temperature and life expectancy of components.In addition, its excellent solubility makes it widely applicable to semi-conductor and display panels.It's a photoresist and a sophisticated cleaning medium.It is a key chemical medium for improving the probabilities of high-tech production.

Advantages
Extreme dissolution efficiency.
As a powerful solvent, the GBL has an excellent solubility for high-molecular polymers (e.g. polyurethane, epoxy resin) and a number of insoluble chemicals, which can effectively increase the efficiency of washing, depainting or chemical reactions.
Excellent physical stability
Ready High boiling point at 204°C Low vapour pressure does not cause loss during operation, and is extremely stable in high temperature or high voltage electrical applications (e.g. capacitors).
Environmental and operational safety
The GBL is more biodegradable than many traditional high toxicity solvents and has higher flashpoints (about 98°C) and is safe and reliable in the right industrial environment.

Security & Save Proposal
Save Condition
- Environmental control: stored in a cold, well-ventilated, specialized warehouse. The temperature of the environment should be kept below 30°C.
- Seal: The GBL has a certain humidity and the container must remain sealed. It is suggested to use steel-free, high-density polyethylene (HDPE) or impregnated steel drums.
- Ban on appliance isolation: Should be separated from oxidizers, thorium, and retrogents, and strictly prohibited from contact with open fire or heat sources.
- Stationary equipment should be installed to prevent static build-up.
Operate environmental and operational advice
- Ventilation: The field should be equipped with a local or overall ventilation system to ensure that the vapour intensity in air is below safety standards.
- Personal protection (PPE):
- Eye: with chemical protection glasses.
- Hand: Use of antichemical rotting gloves (e.g., butler or butyl rubber).
- Respiration: If the environment is insufficiently ventilated, it should be equipped with a standard air vapour overscreen.
- Operating regulations: Strictly prohibit smoking and feeding in the work area; after doing so, clean hands. An emergency shower and eye-washing equipment.
Transport advice
- According to the law, transport must be strictly in accordance with national laws and regulations on chemical transport.
- Packaging inspection: Ensure that the container is undischarged and undamaged before delivery. Loads should be stabilized to prevent heavy impact or fall during transport.
- Summer transport should take a sun-shield to avoid exposure to high temperatures for a long time.
- Vehicle requirements: Transport vehicles should be equipped with the range and quantity of fire-fighting equipment and leaking emergency handling equipment.
