Non-fuel Reservoirs In Automotive

Producers of non-fuel automotive reservoirs demand performance. That’s why they select LyondellBasell’s Lupolen and Hostalen resins, which offer mechanical properties, optimum processability and cost-effective manufacturing benefit.

Typical customer applications include expansion tanks (or surge tanks) and the newly developed Selective Catalytic Reduction (SCR) reservoirs, which are designed to hold a urea/water solution to reduce nitrogen oxides (NOx) from diesel engine emissions to address strict environmental standards.

Selected by customers for expansion tanks, Hostalen PP H1850 is a very low- flow homopolymer with a balance of good stiffness and toughness. The grade features the ability to resist yellowing when in contact with cooling water and offers a high level of creep resistance at elevated temperatures present in the cooling water circuit.

Customers select Lupolen 4261 AG for blow molding and Lupolen 4261 AIM for injection molding due to their unique performance attributes:

  • Environmental stress crack resistance
  • Cold impact strength
  • Processing performance

With an ability to accommodate elastic deformations of 5% or more at temperatures below 0°C, Lupolen resins offer the potential to withstand the expansion of 3.5% (along each dimension) of Adblue ® fluid when freezing at -11.5°C.
