High-performance polyurethane elastomer systems for automotive bushings, jounce bumpers, suspension components, sealing parts, and interior trim. Engineered for IATF 16949 traceability, OE-grade fatigue life, and temperature stability across automotive service envelopes.
Blendpolyol supplies polyurethane elastomer raw material systems for manufacturing automotive suspension bushings, jounce bumpers, steering rack mounts, drivetrain isolators, interior trim components, and exterior sealing parts used in passenger vehicles, commercial trucks, and off-highway equipment.
Our formulations deliver:
Lower control arm + sway bar bushings with tuned damping characteristics.
Microcellular PU jounce bumpers for suspension travel limit cushioning.
Vibration-isolating rack-and-pinion steering mounts.
Engine mounts + transmission mounts for NVH control.
Cast PU components for premium interior surfaces.
Body-on-frame vehicle body mounts for SUVs + light trucks.
Vehicle impact bumper — energy absorption
Drivetrain isolator — NVH control, 10⁷ fatigue cycles

Actual parameters customizable according to formulation design and application requirements.
For precision parts requiring void-free casting.
Suitable for large parts and simple geometries.
Used for cylindrical components requiring uniform density.
Compatible with PU casting machines and automated dispensing.
Besides polyurethane raw materials, Blendpolyol also provides matched equipment and tooling — making us a complete production-line partner, not just a chemical supplier.
We support customers from raw material selection → equipment matching → process optimization → mass production.
Yes. Our automotive-grade production runs under IATF 16949 quality system with full lot traceability, PPAP documentation, and capability indices (Cpk ≥ 1.33) on key formulation parameters. Documentation packs provided per OE customer requirements.
We supply against major OE material specifications including BMW, VW, Toyota, GM, and Ford polyurethane elastomer specs (specific OE specifications under NDA). Share your OE spec sheet and we confirm formulation match + provide compliance test data.
5,000 kg first commercial PO for automotive programs — reflects the documentation overhead. Pilot 100–500 kg available for PPAP-stage qualification.
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 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.
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.
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.
