Definitions
- Polyurethane elastomers are known to have been employed in the construction of industrial rollers, such as paper machine press rolls and paper machine belts.
- the polyurethane elastomers are often the product of a reaction between a polyurethane prepolymer and a curing agent.
- the polyurethane prepolymer is typically made by combining a polyol, typically a Poly (tetra methylene) ether glycol (PTMEG) with an isocyanate.
- PTMEG Poly (tetra methylene) ether glycol
- the curing agent is often either a diamine or a short chain diol.
- Polyurethane elastomers have been selected for use in paper machine press rolls and belts because they exhibit advantages in load bearing capability and abrasion resistance over natural and synthetic rubber materials; this is particularly important for paper mill rolls and belts, where they experience high dynamic loads.
- the rolls and belts are also exposed to high moisture and elevated temperatures.
- PTMEG may be prone to thermo oxidative decomposition and may have low chemical resistance and low resistance to hydrolysis at high
- Embodiments of the invention provide for paper mill equipment that can better withstand the conditions of a paper mill.
- Embodiments encompass paper mill equipment that incorporates a polyurethane layer having a hysteresis value of less than 70% and a permanent set of less than 30%.
- the polyurethane layer includes a polyurethane produced by curing a mixed composition.
- the mixed composition includes at least a urethane prepolymer (A) and at least a curing agent (B) having an active hydrogen group (H).
- the urethane prepolymer (A) has at least one terminal isocyanate group and is obtained by reacting at least a polyisocyanate compound (a) with at least a polycarbonate diol compound (b) having a number average molecular weight of at least 1500 g/mol.

- Curing agent (B) may also optionally include one or more polycarbonate polyols (b) as described above. Curing agent (B) may constitute between 0 and 80 mole % of the one or more polycarbonate polyols. All individual values and subranges from 0 to 80 are included herein and disclosed herein; for example, the one or more polycarbonate polyols may constitute from a lower limit of 0, 1, 5, 10, 15, 20, 25, 30, 40, 50, or 60, to an upper limit of 5, 10, 15, 20, 25, 30, 40, 50, 60, or 70 mole % of the curing agent (B).

- Hysteresis tests In this test, a dog bone is stretched to 100% strain at a rate of 5"/min and then returned back to its original dimension (one stress strain cycle). The area between the curve (stretch and return cycle) is indicative of the energy dissipated and is expressed as the % of the area under the curve obtained when the sample is stretched. The point of zero stress on the return cycle is the permanent set (PS) and it is indicative of the dimensional change the part would undergo when exposed to dynamic loadings.
- PS permanent set
- Embodiments of the polyurethane elastomers have a permanent set of less than 30%, 25%, or less than 21%.
- Micro tensile dog bones are placed in a 160 °C air oven in an aluminum pan for air ageing studies. Retention in tensile properties is measured as a function of time.
- Figure 1 depicts the stress vs. strain curve for Comparative Example A and Example 1.
- the polycarbonate based elastomer, Example 1 has higher modulus but lower elongation as compared to PTMEG based materials (Comparative Example A).
- Prepolymers are prepared by reacting TERATHANE 2000 (7.75 g) and
- the curatives are reacted and cast onto a mould individually with the prepolymer at 75 °C at an index of 1.056 (Example 6-9).
- the prepolymer is the prepolymer of Comparative Example B.
- UH-200 (74.76 g) with ISONATE M 125 (74.76 g) for approximately 4 hours at 80 °C.
- the prepolymer has a NCO content of approximately 10 percent by weight.
- the resulting prepolymer (32 g) is then mixed with a curative agent (ETHACURE 300 (8 g) and poured onto steel plate with spacer (coated with a demold spray), covered with a metal plate; pressured to 10000 psi for 5 minutes.
- the plaques are then cured for 25 h in an oven at 80 °C.
