PU Elastomer Raw Material
For PU Shock Absorption Parts
High-performance polyurethane elastomer systems for vibration dampers, shock-mounts, motor bushings, machinery isolators, and impact-absorption components. Engineered for tunable damping characteristics and fatigue life under cyclic loading.
PU Elastomer Materials for Vibration Damping & Shock Isolation
Blendpolyol supplies polyurethane elastomer raw material systems for manufacturing vibration dampers, motor mounts, shock-absorption bushings, machinery isolators, conveyor anti-vibration pads, and impact-absorbing components for industrial machinery and automotive aftermarket applications.
Our formulations deliver:
- Tunable damping factor (tan δ 0.10–0.30) via formulation control
- High rebound (35–55%) or controlled-damping variants
- Fatigue life 10⁶ – 10⁷ cycles under typical loading
- Service temperature −30°C to +90°C
- Low compression set for long-term isolator dimensional stability

We support customers from raw material selection → equipment matching → process optimization → mass production.
Frequently Asked Questions
How do I specify damping vs rebound for my application?
High-rebound (45–55%) for general vibration isolation where energy return matters. Controlled-damping (tan δ 0.20–0.30) for tuned mass damper applications where energy dissipation is the goal. We tune via prepolymer + chain extender chemistry — share your loading frequency + amplitude and we recommend.
What fatigue life can I expect?
Standard formulations: 10⁶ cycles at 70% peak elastic strain with <15% modulus drop. For 10⁷-cycle applications (wind turbine, heavy industrial), specify reinforced or composite formulation — 25–35% premium pricing.
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.
