18 NOTES FOR PRACTISE

Page 4 of 20: This document contains important information and must be read in its entirety.4

ACRYLONITRILE-BUTADIENE RUBBER (NBR)

Properties

Provided that the compounds are formulated and processed correctly,

the vulcanizates have very good resistance to liquid fuels, mineral oils and

greases, good resistance to aging, high resistance to wear and abrasion, low

permeability to gases and good physical properties (e.g. low compression

set).

Applications

Krynac® is a base polymer for technical rubber articles that are exposed to

mineral oil based fluids and gases: e.g. hoses, seals (including rubber-to-

metal composites), membranes.

Further areas of application are: roll covers, coated fabrics (e.g. membranes,

printing blankets and flexible containers), sheets, thermoinsulation tubes and

sheets, gloves and footwear, conveyor and transmission belts. If Krynac® is

fluxed with PVC in a suitable way, the blend can be applied in hose covers,

cable covers and sponged articles like thermoinsulation with good ozone

resistance.

Properties

Perbunan® is a fast curing NBR rubber. Vulcanizates are characterised by

a high modulus and good sealing force retention when formulated and

processed correctly. Perbunan® grades are available in the range of 18 % to

44 % acrylonitrile content (ACN).

Perbunan® is used for oil resistant rubber articles in general. They are

especially suitable for mineral oil based hydraulic fluids, natural fats and

oils. Vulcanizates based on high ACN grades are also used for fuel-related

applications.

Rubber articles based on Perbunan® are suitable for extreme low tempera-

ture flexibility (low ACN con-tent) and in general for heat resistance up to

120 °C depending on the time of exposure. Further properties are good

abrasion and wear resistance, low gas permeability and good physical

properties. Perbunan® CHM grades are especially designed for molding

applications to reduce the tendency of mold fouling tremendously.

Applications

Perbunan® is preferably used for molded rubber parts such as seals (inclu-

ding rubber-to-metal composites), membranes, vibration dampers and hoses.

They are also used for rubberized fabrics (printing blankets, flexible contai-

ners), roll covers, sheets, conveyor and transmission belts, shoe soles, other

footwear rubber parts, thermoinsulation articles and other applications.

If Perbunan® is fluxed with PVC, the blends are base polymers for colored

ozone resistant articles such as hose covers, cable sheathing and spinning

aprons.

ACRYLONITRILE-BUTADIENE RUBBER (NBR)


Properties

These modifiers are supplied as powders and have excellent chemical, oil

and hydrolysis resistance. Thermoplastics modified with Baymod® N remain

permanently flexible and elastic. They exhibit good low-temperature flexibi-lity,

low fatigue and high abrasion resistanc and improved oil resistance.

In friction materials, Baymod® N is a modifier for resins and improves the

coefficient of friction. The range includes grades in a variety of viscosities and

degrees of crosslinking.

Applications

In addition to typical rubber applications, suitable as polymeric plasticizers

particularly for modifying flexible and semi-rigid PVC, EVA, PU, ABS and

phenolic resins. Solutions of the uncrosslinked grades are used in adhesives,

seals, coatings and friction materials.

POWDERED ACRYLONITRILE-BUTADIENE RUBBER (NBR)


NANO ADDITIVE BASED ON RUBBER (SBR)

Properties

Nanoprene® consists of spherical particles with diameters in the ~ 50 nm

range. Due to a high degree of crosslinking, the particle morphology is stable

even under high shear. Owing to a high crosslink density, the particles will

not dissolve, but will swell in appropriate solvents.

Nanoprene® is produced by emulsion polymerization which allows for the

efficient control of particle size. By this process a Nanoprene® latex is ob-

tained which is subsequently finished by a standard working up procedure.

At the end of the process Nanoprene® bales are obtained.

At present, two Nanoprene® grades are available which differ in the glass

transition temperature (Tg). The Tgs of these two grades are at -77°C and at

-10°C, respectively. Both Nanoprene® grades are hydroxyl modified and have

the same content of hydroxyl groups (see attached table on product range

and typical properties). The hydroxyl groups are located on the surface of the

Nanoprene® particles. As a consequence of hydrogen bonding between the

particles, aggregates are formed and the formation of nano dust is avoided.

Applications

The use of Nanoprene® is particularly beneficial in silica loaded compounds,

which are particularly used for the production of tyre treads and different tyre

parts. In silica compounds, Nanoprene® is not used as a partial replacement

for silica or rubber. Nanoprene® is rather added on top of the other com-

pounding ingredients the loading of which is not changed. Nanoprene® is

used as an „additive“. Also, Nanoprene® containing silica compounds need

to be silanized. For this purpose the conventional silanes known in the indus-

try are used.

The major benefit of Nanoprene® is in the improvement of silica dispersion

and the reduction of silica/silica interactions. As a consequence, hysteresis

is significantly reduced. For hysteresis reduction (reduction of rolling resist-

ance), the best choice is Nanoprene® B M75OH. The use of Nanoprene®

B M75OH is also recommended for winter tyre treads as it results in a reduc-

tion of the storage modulus (E‘) in the temperature range -50°C to 0°C. As a

consequence, the grip on ice and snow is remarkably improved.

Nanoprene® M10 VP with Tg=-10°C is best used to balance rolling resist-

ance and wet skid performance of a tyre tread. For the adjustment of these

two conflicting properties a combination of Nanoprene® B M75OH and

Nanoprene® M10 VP is recommended. In addition, the use of Nanoprene®

in combination with a functionalized Solution-SBR can result in positive

synergisms.

Probably as a consequence of improved silica dispersion, the use of

Nanoprene® results in the improvement of abrasion resistance. This positive

effect does not necessarily show in laboratory tests but is consistently found

in tyre tests. The improvement in abrasion resistance is not influenced by the

Tg of the Nanoprene® grade.

More than 30 patent applications have been filed, which cover the manufac-

turing process, the use of Nanoprene® in thermoplastic materials as well as in

rubber compounds and other application areas.

Properties

The Baymod®L grade consists of high molecular ethylene-vinyl acetate

copolymers (EVM) which are used as high impact modifiers or plasticizers for

PVC and other polymers.

The impact strength achievable using Baymod®L depends on the vinyl

acetate content and the molecular weight. Baymod®L grades containing

about 45 % VA give the highest notched impact strength.

Applications

In addition to typical rubber applications, suitable for production of graft

polymers, modifiers for rigid PVC and as plasticizing polymers in semi-rigid

to flexible PVC compounds.

CHLOROPRENE RUBBER (CR)

Properties

Provided that compounds based on Baypren® are formulated and pro-

cessed correctly, the vulcanizates are highly resistant to weathering and

ozone, have good resistance to aging, hot air and chemicals and display

moderately good resistance to oils and gasoline. They also show a low

gas permeability and good mechanical/physical properties as well as

an excellent abrasion resistance. If suitable formulations are chosen, the

flame retardancy and combustion behaviour of Baypren® vulcanizates can

be tailored to meet special requirements. The properties of Baypren® vul-

canizates are influenced by the type of modification of the raw polymer

(e.g. pre-crosslinking, sulphur or xanthogendisulfide modification).

Applications

Thanks to the excellent set of properties, Baypren® is used for the production

of highly stressed rubber articles in many sectors, primarily in the automotive

industry, mechanical engineering, plant construction, ship-building, mining

and mineral oil production. Typical Baypren® products are (reinforced) hoses,

belts (power transmission and conveyor), bellows, axle boots, air springs,

dampers, cables and insulation for low voltage cables, sponge rubber, corro-

sion-resistant linings, roll covers and wiper blades.
