Polyols
The Lupranol® polyol portfolio offers a diverse range of polyether polyols including conventional and graft polyols with the following typical values.
The Lupranol® graft series are polyether products containing dispersed particles of co-polymerized styrene and acrylonitrile, or SAN particles. These products offer property improvements for certain applications such as flexible foam and urethane elastomers.
The Lupraphen® polyol portfolio offers polyester polyols for CASE and footwear applications. These polyols are optimized for mechanical properties and hydrolysis resistance of the final product.
BASF offers various CASE polyols with molar weights rangin from 450 to 4000 g/mol. CASE polyols with a low molecular weight are produced by KOH catalysis. CASE polyols with a high molecular weight are also available as DMC catalyzed products or are solely produced by the latter technique, which lowers the content of unsaturated, monofunctional by-products to a minimum.

BASF offers a series of reactive polyols for numerous applications. All reactive polyols have an ethylene oxide (EO) end-cap, creating a primary hydroxyl group. All reactive polyols are produced by KOH catalysis and contain an antioxidant package that is free of 2,6-di-tert.butyl-p-cresol (BHT), enabling their usage in applications where low emissions are important. Reactive polyols are mainly used for molded applications like flexible foams, flexible integral foams, RIM and shoe soles, as well as for CASE applications.

BASF offers a series of amine-based polyether polyols. The unique feature of this special designed polyether polyols is its autocatalytic activity. Amine-based polyols require less free catalyst while achieving the same reactivity, and thus enabling the application where low emissions or fast curing are important.
While Lupranol 3402 and Lupranol 3508/1 are only based on propylene oxide (PO), creating secondary hydroxyl groups, Lupranol 1002/1 has an ethylene oxid (EO) end-cap, creating primary hydroxyl groups. All amine-based polyether polyols are free of 2.6-di-tert.butyl-p-cresol (BHT).

BASF offers a series of polymer polyols (GRAFT polyols) for the production of high load bearing (HLB) and high resilience (HR) foams. All polymer polyols contain dispersed styrene/ acrylonitrile (SAN) co-polymers. The dispersions are stable under standard storage conditions. All polymer polyols contain an antioxidant package that is free of 2,6-di-tert.butyl-p-cresol (BHT) and all polymer polyols have low styrene emissions. The highly filled Lupranol 4002/1 and Lupranol 4003/1 are based on KOH technology and so can be used for the production of HR and HLB foams. The products in the non-reactive polymer polyol series Lupranol 4005/1/SC are blends of Lupranol 4002/1 with Lupranol 2072 (KOH polyol) and so are compatible with standard HR polyols and can be used for high resilience (HR) or combustion-modified high resilience (CMHR) foams. Reactive polymer polyol series Lupranol 4010/1/SC are blends of Lupranol 4003/1 with Lupranol 2095 (KOH polyol), making them suitable for HR foam production.

Characteristic for rigid polyols is higher functionalities at lower molecular weights. Rigid polyols have secondary hydroxyl groups only. Mixtures of Lupranol 3300 and Lupranol 3422, Lupranol 3423 or Lupranol 3424 can be used to design rigid polyol functionality and viscosity in a wide range. Rigid polyols are used in foamed and solid applications or in combination with polyols with a higher molecular weight to increase hardness of the final product. Lupanol 3504/1 and Lupanol 3505/1 are short-chain polyols of the crosslinker type. While Lupranol 3504/1 is based on propylene oxide (PO), creating secondary hydroxyl groups. Lupranol 3505/1 is based on ethylene oxide (EO), creating primary hydroxyl groups.
