PU Elastomer Raw Material
For PU Rollers & Industrial Coating
High-performance polyurethane elastomer systems for industrial coating rollers, printing rollers, paper-industry rollers, and precision surface-finishing components. Engineered for solvent resistance, dimensional stability, and consistent surface hardness.
PU Elastomer Materials for Coating, Printing & Industrial Rollers
Blendpolyol supplies polyurethane elastomer raw material systems for manufacturing industrial coating rollers, gravure printing rollers, paper-mill press rollers, lamination rollers, and surface-finishing rotary components used in continuous-throughput production lines.
Our formulations deliver:
- Solvent & chemical resistance (ink / coating / oil chemistry)
- Stable surface hardness across roller diameter (Shore A ±2 tolerance)
- Low compression set under continuous belt loading
- Hydrolysis resistance for humid pulp + paper environments
- Consistent crowning & concentricity for precision web alignment
Typical Applications
Gravure Printing Rollers
Stable elasticity + solvent resistance for ink chemistry, Shore A 70–90.
Paper Mill Press Rollers
Hydrolysis-resistant polyether systems for wet-end paper-machine sections.
Coating Lamination Rollers
Heat-stable formulations for hot-melt and solvent-based coating lines.
Industrial Surface Rollers

We support customers from raw material selection → equipment matching → process optimization → mass production.
Frequently Asked Questions
Why polyether instead of polyester for paper-mill rollers?
Polyether-based PU has superior hydrolytic stability. After 1,000-hour exposure at 50°C / 95% RH per ASTM D1183, polyether systems retain ≥ 90% of bondline strength vs 50–70% for polyester. For wet-end paper-machine sections, polyether is the only practical chemistry.
Can you supply rollers with embedded steel cores?
We supply raw material; roller manufacturing (casting around steel cores) is done by your facility or a partner converter. We can introduce qualified converters in your region.
What hardness range can you provide?
We provide formulations from soft elastomer systems (Shore A 60–70) to ultra-hard industrial materials (Shore D 70–75). Specific hardness is tuned via prepolymer NCO content + chain extender ratio.
MDI vs TDI systems — which is right for me?
MDI systems provide higher load-bearing performance and lower toxicity (no free TDI vapor) — preferred for indoor casting. TDI systems offer better elasticity, rebound, and abrasion resistance — preferred for dynamic-load and high-wear applications.
Can you customize formulations?
Yes. We customize hardness, rebound, abrasion resistance, chemistry resistance, and processing characteristics. Custom formulation MOQ is typically 1,000 kg; development cycle 3–5 weeks including bench testing and customer-site trial.
Do you provide complete production solutions?
Yes. We supply raw materials, casting machines, mixing systems, custom molds, heating systems, and production line engineering support. End-to-end onboarding from formulation selection to mass production typically takes 3–4 months.
