Catalysts

Polyols

Lupragen

BASF has more than 15 PUR amine catalysts in its product portfolio that make

it a world leader in this segment. The company markets high-performance

reaction accelerators under the Lupragen® brand, including extremely

low-emission PUR catalysts.

As the world‘s leading chemical company BASF is offering excellent and

consistent product quality, high supplier reliability, and worldwide product

availability with dedicated production facilities in Europe and North America.

PUR catalysts are usually tertiary amines. They are required to facilitate the

reaction of the main components isocyanate and polyol. Depending on the

catalyst choice the polyurethane forming process can be controlled to favor

the gelling or blowing reaction. This behavior leads to PUR material with the

desired properties, depending on whether the final product is to be a rigid,

semi-rigid or flexible foam (see pages 12/13).

BASF Lupragen catalysts offer the following advantages

■ One-stop product portfolio covering all desired application areas from rigid to flexible PUR foam

■ Availability of low-VOC catalysts addressing increasing environmental and health issues in end-consumer products

■ Excellent and consistent catalyst quality

Butanediol (BDO)

BASF is the world’s biggest producer of 1,4-butanediol (BDO)

and its derivatives. BDO is a bifunctional alcohol that is very

widely used in the chemical industry. The terminal OH in

each of the –CH2OH groups of BDO can be reacted with

numerous monofunctional and bifunctional compounds, for

example to form polyesters with dicarboxylic acids, PUR with

diisocyanates, and polycarbonates with phosgene. It is also

used as a building block in the production of polyester

polyols and polyether polyols.

BDO and its derivatives are used for producing engineering

plastics, PUR, solvents, electronic chemicals and elastic fibers.

Main BDO reaction types in PUR chemistry:

■ BDO + dicarboxylic acids polyester polyols

■ BDO + alkylene oxides polyether polyols

■ BDO + diisocyanates PUR

Polytetrahydrofuran (PolyTHF):

PolyTHF® is one of the main soft segments for thermoplastic

elastomers and crosslinked elastomers.

The hard segment of thermoplastic elastomers generally consists

of chain extenders such as short-chain diols (e.g. 1,4-butanediol)

and diamines (e.g. 1,2-propylenediamine). The amorphous soft

segment (PolyTHF) not only imparts elasticity and low-tempera-

ture flexibility to the finished product but influences the chemical

behavior as well. Careful adjustment of the soft segment fine-

tunes the desired properties of the final application.

BASF is the global market leader in PolyTHF production

and manufactures a wide range of PolyTHF molecular weights,

including the standard molecular weights 650, 1,000 and 2,000;

as well as the special molecular weight 250 (technical grade).

PolyTHF is the ideal soft segment for PUR with:

■ Excellent dynamic mechanical properties across a wide temperature range

■ Exceptional low-temperature behavior

■ Superior hydrolytic stability

■ High moisture vapor transmission

■ Excellent abrasion resistance

■ High microbial resistance

The physical and chemical properties of PolyTHF give it advantages over competitive materials such as polyester polyols, due in particular to its superior hydrolytic stability and microbial resistance.

Hexanediol (HDO)

1,6-Hexanediol (HDO) is a valuable specialty intermediate

chemical with many applications. A linear diol containing two

primary hydroxyl groups, HDO is a white, waxy solid at room

temperature and melts easily to a clear liquid at temperatures

above its melting range of 40 – 42 °C.

HDO is produced at our global Verbund sites in Ludwigshafen,

Germany, and Freeport, Texas. Molten HDO and HDO flakes

are the grades supplied.

HDO undergoes all reactions typical of primary alcohols.

HDO properties are of particular value in the manufacture of

polyester polyols used in PUR elastomers, PUR dispersions,

coatings and adhesives. Downstream applications of the above

include protective and industrial coatings, microcellular PUR,

cast elastomers, fibers, cosmetics, printing inks and many

more. HDO can also be used as a chain extender.

HDO-based polyester polyols can be used as soft fibre in polymers and are characterized by

■ High resistance to hydrolysis

■ Good physical properties

■ Low glass transition temperature

■ Dry grip

Pure potential: 1,5-pentanediol (PDO)

1,5-Pentanediol (PDO) is a bifunctional alcohol used in the

synthesis of innovative TPU, polyester resins, plasticizers,

pharmaceuticals, crop protection agents and piperidine.

Our high-quality PDO opens up new opportunities in the

organic synthesis of products requiring a 5-carbon unit.

Trimethylolpropane (TMP)

Trimethylolpropane (TMP) is a major intermediate with a wide range of

applications in the chemical industry, the main ones being polyester polyols,

polyether polyols, binders and adhesives, synthetic lubricants, polyester and

alkyd resin coatings.

TMP with its three primary alcohol groups is used as a three-functional cross-

linking agent. It is a white solid at room temperature and easily melts to give a

clear liquid at temperatures above its melting range of 58 – 60 °C.

TMP has a wide variety of applications, with a quaternary structure providing:

■ Superior hydrolytic stability

■ Weatherability

■ A good balance between hardness and flexibility

Capromer polycaprolactones

Capromer™ polycaprolactones are speciality polyols for

high-performance PUR applications. Low-viscosity di- and trifunctional poly-

ols are available as components for isocyanate-based formulation systems.

Capromers offer outstanding low-temperature flexibility for thermoplastic

elastomers used in technical applications and coatings. BASF’s Capromers

are used where high hydrolytic stability is required together with good

light-fastness. The polycaprolactones have a very low melting viscosity for

easy processing of PUR elastomers. Capromer-based PUR dispersions are

the best choice for any textile and leather application. For coatings applica-

tions the low viscosity facilitates high-solids systems or even solvent-free

formulations. Such coatings offer excellent weatherability and chemical

resistance.

Trifunctional Capromers have extraordinarily low viscosity and increase the

resistance in any PU-based adhesives and coatings consistent reactivity.

The unique manufacturing process results in Capromers of unique quality

with low catalyst levels for consistent reactivity of the PUR reaction in your

process.

Capromers are available as standard grades and as premium grades with

reduced acid value for even greater hydrolytic stability.

Additives

Ethanolamines (EOA)

are used in various PUR applications as chain extenders and cross-linkers.

Mono-, di- and triethanolamine (MEOA, DEOA, TEOA) forms exist. DEOA and

TEOA may be used as polymerization starters in polyol manufacture. The

catalytic effect also provides a means of controlling the foaming rate and sub-

sequent curing. BASF offers a high level of supplier reliability as a European

market leader with full backward integration into raw materials and plants in

Germany, Belgium and China. The company also has an extensive product

range with a variety of solutions and mixtures. MEOA, DEOA and TEOA are

produced from synthesis of ethylene oxide and ammonia. In addition to pure

grades and an array of mixtures and solutions, BASF supplies a mixture of

TEOA and DEOA created especially for the PUR market and sold under the

product name Triethanolamine S.

Methyldiethanolamine (MDEOA)

is an amine-based polyol that is suitable for use as a PUR catalyst and as a

special polyol in PUR synthesis. A double-action additive (catalyst and polyol),

MDEOA is also a useful cross-linker and chain extender. BASF is the world’s

only manufacturer with full backward integration covering all the raw materials

contained in MDEOA.

N4-Amine

is making a name as a special catalyst in the flexible foam segment. The high

amine content significantly reduces starting time. This property is an advan-

tage when rapid foam injection is required.

Solvents

Propylene carbonate

BASF is a leading producer of propylene carbonate (PC) with an integrated

production site in Ludwigshafen, Germany. Expertise in the production of PC

combined with fully backward-integrated production sites in all major con-

sumption areas make BASF the poly urethane industry’s supplier and partner

of choice.

As the world’s leading chemical company, BASF has many years of expe-

rience in PC with regard to issues such as health, sustainability, product

stewardship, safety and the environment. We share this expertise to make our

customers more successful.

Propylene Carbonate has a number of beneficial properties and characteris-

tics in urethane chemistry applications. It can be used as a viscosity reducer,

compatibilizer, reactive diluent and plasticizer in urethane systems.

Other fields of applications for propylene carbonate are:

■ Solvent replacement for toxic solvents (low toxicity and non-irritability)

Aminoethylethanol amine (AEEA)

is used as a chain extender and cross-linker for PUR and affects polymer

properties accordingly. The product’s bifunctionality is a requirement for its

use in these areas. Both the hydroxy and the amine function react very well

with isocyanates.

Isopropanolamines

Monoisopropanolamine (MIPOA), diisopropanolamine (DIPOA) and triisopro-

panolamine (TIPOA) are suitable as PUR additive.

In the manufacture of flexible foams, these products can be used in order to

adjust parameters like tensile and tear strength and can aid in high-tempera-

ture resistance.

Basionics antistatics

BasionicsTM are outstanding new additives to provide antistatic properties

to polyurethanes. Basionics antistatics may be applied to a wide range of

PUR products, from low-density flexible foams, to microcellular materials, to

compact PUR materials like cast elastomers or TPU. They allow a targeted

selection in terms of conductivity, matrix compatibility and insertability and

offer wide formulation flexibility.

As Basionics are transparent, manufacturers can produce naturally colored as

well as tinted products. The wide window of thermal stability allows their use

in nearly all common PUR manufacturing and application processes.
