Product Description

 

3M™ Dyneon™ Fluoroplastic Granules THV 221GZ is a flexible, transparent fluoroplastic composed of

tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride in the form of pellets. It provides a balance

 

of low temperature processing, low flammability, thermal stability, and melt processability. It can be used to prepare extruded films, tubes, profiles, and wire coatings. It is useful for applications that require a high level of flexibility, transparency, low temperature fusion or bonding capability with moderate chemical resistance. Laminated films of this product exhibit

 

excellent weatherability and good anti-soiling properties. This product can be E-beam cured without the need

 

of pro-rads to improve its high temperature capability with minimal loss of flexibility. Process at relatively low temperatures compared to other fluoroplastics and may not require the same level of corrosion resistant equipment as that used with higher melting fluoroplastics. However, it should be remembered that

 

THV is a fluoroplastic and should be treated accordingly.

 

Storage and Material Handling

 

Dyneon THV 221GZ has an unlimited shelf life provided it is stored in a clean, dry place. THV 221GZ is hydrophobic, and generally does not require drying before processing unless high humidity conditions create surface moisture adsorption.

 

 

Safety/Toxicology

 

This is a fluoroplastic material, so normal precautions observed with fluoroplastics should be followed. Before processing this product, be sure to read and follow all precautions and directions for use contained in the product label and the Material Safety Data Sheet. General handling/processing precautions include: (1) Process only in well-ventilated areas; (2) Do not smoke in areas contaminated with powder/residue from this product;

 

(3) Avoid eye contact; (4) After handling this product, wash any contacted skin with soap and water. Potential hazards, including evolution of toxic vapors, can exist if processing occurs under excessively high temperature conditions. Appropriate local exhaust ventilation such as vapor extractor units should be installed above processing equipment. When cleaning processing equipment, do not burn off any of this product with an open flame or

 

in a furnace.

 

Product Form and Packaging

 

THV 221GZ pellets are supplied in 25 kg (55 Ib) polyethylene bags.
