About Dolanit^®

Dolanit^® Type 10 D

"The tailor-made solution for friction pads"

Dolanit^® 10 D is a high tenecity, short staple, homopolymer acrylic fibre. It has been effectively used for friction pads. It meets all the fibre requirements of large brake pads used for large trucks or rail cars for example. For other applications, such as wheel disc brakes, Dolanit^® is blended with aramide fibres for improved strength properties.

Dolanit^® 10 D is availbable in 3.0 dtex with a staple length of 6mm. The moisture content is less than 2 percent. (Higher moisture contents available on request.) It can be supplied in bales (approx. 280kg) or bags (10 or 20kg).

Dolanit^® Type 12

"Ideal for Filtration"

Dolanit^® 12 is a crimped homopolymer acrylic fibre, which combines superb strenght and resistance along with increased durability and good processability. It is a high-performance, cost effective solution for filtration applications.

APPLCIATIONS:
Woven and nonwoven fabrics for dust filtration, e.g. in coal-fired power stations, garbage incinerators, cement works, primary and secondary smelters and heavy metal industry plants.

CHARACTERISTICS:

Processability - surface structure, crimp and friction properties result in easy processability with problem-free carding, needle punching and spinning
Resistance and stability - Dolanit^® 12 has a higher temperature stability, greater hydrolysis and chemical resistance than copolymer acrylic fibres.
Strength - Dolanit^® 12 has a consistently high tensile strength in fibre and yarn

AVAILABILITY
Dolanit^® 12 is available in four fibre counts: 0.9 dtex microfibre (40mm cut length) for special felts; 1.7 dtex (50mm cut length) and 2.2 dtex (60 or 80 mm cut length) for spun yarns and felts and 8.2 dtex (80 mm cut length) for felts.

Polyacrylonitrile

"Main component for the industry"

We also offer Polyacrylonitrile in the form of two different polymer powders:

- Co-Polymer with 6% methyl acrylate, Molar weight: 80.000 g/mol
- Homo-Polymer with over 99.5 % Acrylonitrile, Molar weight: 200.000 g/mol

The average grain size is approximately 40 microns. Suitable solvents are DMF, DMAc and other solvent systems.

Polyacrylonitrile powder can be utilized in various areas - e.g. as solvent for the build-up of coatings and membranes or as direct additive for friction pads. Following a chemical modification it can also be used in the form of gel or water soluble polymer as a flocculant for waste water treatment. These products can even be optimized to bind heavy metals and remove them from waste water.

Tell us your needs and we will gladly support you with a customized solution. Our polymer capacity is several 10,000 tons / annum and we can assist you in developing a product which suits your needs.

Polyacrylonitrile powder is supplied in big bags of approximately 320kg.
Different packaging can be arranged upon request.
