the contracting authority requires that the subject of the contract (concerns vertical type vertical blinds) has current certificates of fire retardancy
and hygienic attestation
These chemicals may be used in combination with some other chemicals or used singly to impart flame retardancy
. Moreover, selection of a particular chemical depends on the material to which it is to be added as different elements which compose the chemical react differently with fire.
A range of specialised finishes is also available to ad custom characteristics, such as flame retardancy
, anti-static and Teflon coatings.
Performance characteristics include excellent chemical resistance, flexibility, low-temperature resistance, and inherent flame retardancy
The company offers specialty additive products which are said to provide end use application performance attributes, including anti-fog, anti-static, anti-block, anti-slip, anti-stick, antibacterial, fire retardancy
, UV protection for film packaging, as well as biodegradable, fully recyclable grades.
However, the low water resistance of PER, due to its four hydroxyl groups, leads to a severe deterioration of the flame retardancy
. The results of Figure 6 show that the flame retardancy
of HIPS increases with the content of MWNT.
However, during those many years I was told on lots of occasions by fabric suppliers that the chemicals which achieve flame retardancy
give off toxic fumes when fire strikes, which are as much a danger to people's lives as the flames themselves.
Melamine cyanurate (MCA), as a traditional flame retardant, is usually used in PA6, which is halogen-free and can significantly improve the fire retardancy
Surface coatings of melamine-modified urea-formaldehyde resins (MUFs) containing ammonium polyphosphate (APP) have been shown to significantly improve the fire retardancy
of wood by prolonging the ignition time and reducing the heat release rate, total heat released, and mass loss rate.
The acquisition adds a broad range of additive solutions with different functionalities, such as antifogging, improved processing, flame retardancy
, heat stabilization and UV stabilization to BYK's portfolio.
It's said to offer the possibility of further miniaturization and enhanced aesthetics to the consumer electronics market in Asia--combining the characteristics of halogen-free flame retardancy
with high flow and low migration, while reducing corrosion in the injection molding process.
