The new polyethylene will be used to make fuel tanks

Closely monitoring the latest trends and needs of its Clients, Braskem has developed a new automotive resin. The enhancement of its portfolio aims to expand the offering of high-quality products that are aligned with the latest trends in the international market. The new polyethylene grades that were recently shipped to clients will have applications for fuel storage systems and include the resins HS4506 and HS4506A.  

"The use of polyethylene to make fuel tanks combines increased safety, lower weight and greater design freedom in relation to metal, which allows for designs that make better use of the room available in vehicles for installing the fuel tanks. Today, 67% of vehicle tanks in Brazil are made from polyethylene," said Claudia Arruda, commercial director at Braskem.

Braskem's new grades and the unique combination of the production process, catalyzer and comonomers used make possible products with molecular structures that are unique from those currently obtained. This means that the new resins offer improved processability, increased chemical and corrosion resistance, lighter weight, greater durability, better compatibility with other resins and low thermal conduction.

The resin HS4506 was developed for the production of automotive fuel tanks, as well as filler tubes and cold-start reservoirs. The resin is also recommended for the production of fluoridated and co-extruded tanks.

Meanwhile, the HS4506A resin contains special additives that ensure greater resistance to ultraviolet radiation and weather conditions. The resin can be used to make fuel tanks for trucks and for the aftermarket auto parts segment. One of its mean features is its homogeneous appearance, which makes it ideal for exposed tanks, such as on trucks.
