Safety precautions

The homopolymer of vinylidene fluoride (VQF) begin to have a slight decomposition with HF gas released above300°C. Avoid processing or using the products at the temperature above 370°C in order to prevent toxic gas release

Workers should avoid breathing in harmful gases during processing and wear necessary labor protection stuff.

Keep the dust away from being breathed in nasal cavity and infecting eyes.

After production, have a complete clean up of faces and hands.

Disposal of the wastes produced in the processing must be dealt with by specialized personnel for waste disposal and should be conducted according to waste regulations in relevant countries, regions and local places,

Before processing, please read the safety data sheet carefully.

Storage and disposal

The products should be stored in clean, cool, shady, and dry warehouses so as to avoid the mix with dust and moisture. During transportation, violent vibration must be avoided. Prevent any cases aggregation
