The first rollers have to hold the most amount of heat, so we use PBO; then we use Kevlar rollers as the profile cools profile goes to a cooling table where it moves back and forth to cool down.

2 We normally use Kevlar for this there are 2 or 3 cooling tables, as the profile gets colder we can start using less costly materials like Nomex or at the end of the process there is a saw that cuts the profile. Here it is much cooler so we can use aluminum billet gets heated up and then pressed through a die to give it the desired Cooling TableSecond Cooling TableSizing TablePickup Table1050 F850 F580 F300 F750 F850 FExtruderExtruderPBOPBO stands for Polybenzobisoxazole, which is a synthetic polymer that was invented by SRI International and is currently manufactured by Toyobo Corporation in Japan.

3 The trademark name for PBO is Zylon. Zylon is times stronger than Kevlar and can also withstand higher aluminum extrusion, PBO normally can withstand temperatures up to 1200 F / 600 is the trademark name for an aramid fiber made by DuPont. An aramid fiber is a synthetic (man-made) fiber that is very strong and heat resistant. Aramids are generally prepared by the reaction between an amine GROUP and a carboxylic acid halide GROUP . The most popular aramid fibers are: Kevlar, Twaron, Technora and Heracron. The one that we and most of the market use is Kevlar.

4 Kevlar is made by a solution of monomers 1,4 phenylene-diamine and terepththaloyl chloride in a condensation aluminum extrusion, Kevlar normally can withstand temperatures up to 950 F / 500 is the trademark for a flame-resistant meta-aramid developed by DuPont. Nomex, like Kevlar is an aramid but Nomex is a meta aramid, and Kevlar is a para aramid. The variant meta just has a di erent location for the di erent compounds than the variant para . This makes Nomex have an good thermal, chemical and radiation resistance for a polymer material.

5 For example the firefighters suits are made of Nomex because of its resistance to fire and But this also makes Nomex to have a poorer strength and a lower resistance to heat than Kevlar. Nomex is made in USA and also Spain by the aluminum extrusion process it can withstand 450 F / 230 is a synthetic polymer made of purified terephthalic acid (PTA) or its dimethyl esterdimethyl terephthalate (DMT) and monoethylene glycol. It doesn t have high resistant to heat, that is why is normally used at the very end of the process where the profile is cooler.
