DOW HYPERLAST Expands the DIPRANE™ and HYPERLAST™ Polyurethane Elastomers Product Lines


Dow Hyperlast is expanding the DIPRANE™ and HYPERLAST™ polyurethane elastomers product lines with the addition of VORASTAR™ TDI-based prepolymers from Dow Polyurethanes, a business unit of The Dow Chemical Company (“Dow”). VORASTAR prepolymers, which will now be rebranded under the globally recognized trade names DIPRANE and HYPERLAST, enable the extension of the currently available range of quasi prepolymer systems.

These prepolymers are distinctly suitable in areas where wear and tear and durability are critical application requirements, such as mining, material handling and a multitude of industrial uses. The product line expansion is the result of synergies realized through Dow’s acquisition of Hyperlast Limited in May 2007.

HYPERLAST prepolymer systems predominantly based on polyether polyols produce elastomers with excellent dynamic performance and toughness, offering very good performance in cold and wet environments.

HYPERLAST prepolymer systems derived from polyols and TDI produce elastomers with strong dynamic performance, resilience, hydrolysis resistance and performance at low temperatures. These are ideal for high speed/high load bearing applications and suited to cold or wet environments or a combination of both.

DIPRANE prepolymers, derived from polyester or polycaprolactone with TDI or MDI, produce tough, durable elastomers with excellent resistance to wear and tear, cuts, flex fatigue and organic chemicals. These are ideal for applications including wheels, rollers and mining equipment such as screens, scrapers and conveyors, can be tailored to provide elastomers capable of excellent solvent resistance.

The newly expanded product line is available globally through the Dow Polyurethanes sales network which offers direct technical support from the local systems houses.

HYPERLAST™ and DIPRANE™ polyurethane systems were developed by Dow Hyperlast, part of Dow Polyurethane Systems, a business group of Dow. The comprehensive product line covers applications from concrete coatings to offshore pipelines, automotive suspension components, rail and tramway components, tooling and furniture edging and is used in the manufacturing, engineering, transportation, architectural, marine, industrial and other sectors.

A leading polyurethane systems house, Dow Hyperlast is committed to applying its 30 years’ experience to continue developing innovative materials, products and solutions for the benefit of customers worldwide. The commitment is demonstrated by multi-million dollar investment in research and manufacturing facilities.
