Further applications are thermosets, where APP is used in unsaturated polyesters and gel coats ( APP blends with synergists ), epoxies and polyurethane castings ( intumescent systems ).
22.
Zinc borate is used in polyvinyl chloride, polyolefins, polyamides, epoxy resins, polyesters, thermoplastic elastomers, rubbers, etc . It is also used in some intumescent systems.
23.
Intumescent firestops are often used, in the event plastic pipes are used for toilet drains, so that the melting plastic pipe is choked off in the event of an accidental fire.
24.
For countries that use a hose-stream test, the Fomox is reinforced with intumescent graphite, whereas for those who do not use a hose-stream, this ingredient is omitted.
25.
Plenty of paint-makers tout " intumescent " products that resist fire, according to Lucho Mauricio, business agent for the International Brotherhood of Painters and Allied Trades in San Francisco.
26.
Not unlike other intumescents, sodium silicate, both in bead form and in liquid form, are inherently endothermic, due to liquid water in the water glass and hydrates in the prill form.
27.
There are tests on systems, such as the one below, but there are also tests on materials, such as intumescents, to be sure of components that may be used within a system.
28.
This is achieved by using a clear intumescent layer sandwiched between glass panels ( an interlayer ) formed of silica nanoparticles ( SiO 2 ), which turns into a rigid and opaque fire shield when heated.
29.
Smoke will migrate through the interior of a cable bundle if the bundle is not opened up and sealed on the inside during the installation of any firestop, regardless of whether the firestop is intumescent or not.
30.
Because of the relatively low thickness of this intumescent coating ( usually in the 350-to 700-micrometer range ), nice finish, and anti-corrosive nature, intumescent coatings are preferred on the basis of aesthetics and performance.
