High-performance polyurethane elastomer systems for vibrating screens, mining screen panels, hydrocyclone liners, chute liners, and heavy-impact wear parts. Engineered for ultra-high abrasion resistance and impact tolerance in harsh mining environments.
Blendpolyol supplies polyurethane elastomer raw material systems for manufacturing vibrating screen panels, hydrocyclone liners, transfer chute liners, slurry-pump components, dewatering screens, and heavy-impact wear parts used in mining, mineral processing, and aggregate operations.
Our formulations deliver:
Open-area customized for specific cut sizes (0.5 mm – 100 mm aperture).
Slurry-handling cyclone underflow / overflow protection.
Impact + sliding wear protection for ore transfer points.
Impeller covers, suction liners, dispatch components.
High open-area for fine-particle dewatering operations.
Polyurethane composite mill-liner systems for AG / SAG mills.
Vibrating screen panel — Shore A 60-95 cushion + cut
Hydrocyclone / sieve bend installation
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.
PU screen panels typically run 3–8× longer service life than NR/SBR rubber under same conditions. Higher upfront cost but lower total cost per ton processed. PU also gives consistent aperture stability — no aperture creep over service life.
Our Shore D 65–75 hot-cast TDI systems handle hard-rock crushing applications (granite, basalt, iron ore). For ultra-hard ore (e.g., taconite, magnetite), we can supply ceramic-loaded composite systems.
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.
