A printing press is a punishing place for a soft part. Rollers and blades run at high speed, soaked in inks and solvents and dragged across abrasive substrates. Rubber components swell in that chemistry, wear under the friction, and eventually force a line stop for replacement — and every stop costs production time you can’t…
Automotive and heavy-machinery buyers increasingly swap rubber and metal parts for polyurethane in suspension bushings, mounts, seals, and seating. The performance case is well known. What most supplier pages skip is what matters at the spec sheet: which grade to specify, and how much longer it actually lasts. Automotive polyurethane is an elastomeric material used…
When you order a custom polyurethane component, no catalogue page tells you which grade to specify. That decision lands on your desk before the manufacturer can quote — and if you get it wrong, you’ll find out through early failure rather than the specification sheet. Polyurethane material selection matches base chemistry, Shore hardness, and additive…
Steel mills and printing presses may seem like they have little in common, but both rely on polyurethane roller coatings — and each environment makes almost opposite demands on the coating material. Polyurethane roller coatings are used in steel mills and printing facilities because they combine high abrasion resistance with precise hardness control. Steel mill…
When ink deposit quality goes wrong on a production run, most printers reach for the obvious controls first: mesh count, squeegee angle, pressure, ink viscosity. The blade’s hardness rating rarely gets questioned — yet it is one of the most common, least-diagnosed sources of deposit inconsistency. A blade selected at the right durometer for the…
Choosing between polyurethane and rubber squeegees affects edge life, chemical compatibility, and total replacement cost — not just unit price. Get it wrong and you’ll face faster blade degradation, inconsistent print quality, or swollen blades in solvent-heavy environments. Polyurethane vs rubber squeegees differ most in edge retention, chemical resistance, and long-term cost-per-use across demanding applications….
The phrase “polyurethane is oil-resistant” is true, but it is only half the answer. The formulation type — not just the material category — determines whether the seal holds or swells. Get the grade wrong and you face dimensional loss, sealing-force drop, and premature replacement. Polyurethane oil resistance gaskets seal against petroleum oils, hydraulic fluids,…
Engineers specifying material handling components face a fragmented market. Belts, rollers, and coatings come from different suppliers, and few sources explain which product type fits which application — or how hardness specification translates into measurable wear performance. The phrase “FDA-compliant” appears on almost every product page, but almost none explain what it actually means for…
For most industrial sealing applications, the choice between polyurethane and EPDM (ethylene propylene diene monomer) comes down to one question: what fluid will the seal contact? Polyurethane gaskets and seals covers the product category in full — this guide focuses on the specific PU vs EPDM comparison. Polyurethane and EPDM both serve industrial sealing applications,…
Shore hardness is the first number most engineers reach for when specifying a polyurethane board or sheet. It’s visible, comparable, and easy to call out on a purchase order. But hardness alone does not predict wear performance across chemistry families — and in abrasion-critical applications, that gap makes the difference between a liner that lasts…
