Cast
Polyurethanes
Cast Polyurethanes are cost effective and
dependable elastomers that combine the performance
advantages of engineering plastics, metals and ceramics along with the
resiliency and flexibility of rubber. These are internationally
popular for their high load bearing capacity, high impact strength,
high abrasion resistance, high resilience and excellent resistance to
oil and grease.
The applications of polyurethanes include where the actions of
sliding, bearing, stripping, forming, damping, cushioning, resting or
rolling are involved.
For optimum performance, better results and longer life, selection of
appropriate grades is important. These can be formulated with
permutation & combination of selective chemicals & additives.
Cast Polyurethanes have unlimited running applications & a huge
replacement market is waiting to turn on.
Applications:
Pads: Abrasion Resistant Linings, Gear Seals, Jigs & Fixtures,
Mallets, Punch-strippers, Screens, Spacers, Rollers & Sleeves,
Suspension Bushes, Scrapper Blades, Wheels, Wear Parts etc.

Thermoplastic
Urethane (TPU)
Thermoplastic Urethane (TPU) results from copolymerization of two or
more monomers. One monomer is used to provide the hard, crystalline
features, whereas the other monomer produces the soft, amorphous
features. Combined these form a thermoplastic material that exhibits
properties similar to the hard, vulcanized elastomers.
Because of its toughness and versatility, as well as a generally
higher price tag than other TPEs, urethane is typically used for parts
requiring a high level of performance. These applications frequently
demand a flexible material with a high degree of flex resistance,
wearability, and durability. Particularly at lower temperatures, other
materials do not provide this combination of properties.
