Technical Information elastomer
Use in elastomer applications
Use of DURANOL™ allows you to obtain thermoplastic and thermosetting elastomer and resin with excellent chemical resistance, abrasion resistance, and flexibility. DURANOL™ is used in a wide range of fields such as various rollers, rolls, belts, sealing, and gaskets.
Flexibility of DURANOL™
Generally, although PCD polyurethane tends to lack flexibility, use of liquid type DURANOL™ allows improvement of flexibility.
Tensile test of polyurethane
[Measurement condition]
Polyurethane formulation: MDI / Polyol / 1, 4 - BDO = 2 / 1 / 1
Condition: According to JIS K7311
Test piece: 2 mm × 60 mm strip
Measuring instrument: TENSILON tensile testing machine
Heat resistance of DURANOL™
PCD polyurethanes show high strength retention even after storage at a high temperature.
Change in the property of a polyurethane film stored at 120°C
[Polyurethane formulation] H12MDI/Polyol/IPDA=2/1/1
Hydrolysis resistance of DURANOL™
It can be seen that PCD polyurethanes are hard to decompose when compared to polyether urethanes and polyester urethanes.
