含氟聚合物 (Fluoropolymer): Hylar®

Product Availability Product Description
Hylar® 301S Europe
Hylar® 301S is a high melt viscosity polyvinylidene fluoride (PVDF) powder used for for non-architectural dispersion coatings.
Hylar® 5000 HG Europe
Hylar® 5000 HG is a crystalline high molecular weight powder form of polyvinylidene fluoride (PVDF)specifically designed for solvent-based coatings to provide improved gloss. It forms mechanically strong and tough films that have a broad useful temperature range. These films are highly resistant to most environmental conditions including gamma radiation and are essentially transparent to ultraviolet radiation. The weathering characteristics of Hylar® 5000 HG coatings lead to excellent performance for the long term. Hylar® 5000 is available only via a licensing program that specifies the composition of Hylar® 5000 HG coatings. A properly formulated finish contains sufficient pigment to make the film totally opaque to ultraviolet radiation at the nominal one mil (0.001 inch) film thickness suggested. SAFETY Hylar® 5000 HG is stable at temperatures up to 600°F (316°C). When it is subjected to temperatures above 600°F (316°C) for extended periods of time, hydrogen fluoride (HF) begins to evolve, and at temperatures above 700°F (371°C) HF evolution becomes rapid. Hylar® 5000 HG exhibits excellent flame resistance; however, in case of fire, HF and traces of potentially toxic fluorocarbons can be formed. HF is corrosive, causes burns on contact, and has an American Conference Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV-TWA) of 3 ppm (2.5 mg/m³) (1984). Thermal decomposition of Hylar® 5000 HG to HF can also occur in a bake oven in the event that temperatures are not controlled properly. In the event of fire, use NIOSH approved self-contained breathing apparatus and skin protection to protect against volatile decomposition products. Hylar® 5000 HG can be disposed of in an approved land fill, but should not be incinerated unless permitted by applicable law and provision is made for absorption of HF.

Hylar® Latex 932 Europe
Hylar® Latex 932 is a stabilized aqueous dispersion that contains approximately 22% by weight of a high molecular weight PVDF polymer (polyvinylidene fluoride) of medium crystallinity. The dispersion contains a non-ionic surfactant to stabilize against coagulation by conventional means. Hylar® Latex 932 is useful for applications such as water-based coatings and fabric impregnation.
