Professional Polyurethane Prepolymer Manufacturer
聚氨酯预聚体（CPU）专业制造商
R&D, manufacturing and sales of polyurethane prepolymers and premium PU products — formulation development capability and fast technical service to take hardness, strength, elasticity, wear resistance, thermal conductivity and insulation beyond your working-condition requirements.
Products span cast PU prepolymers (CPU), potting & structural adhesives, PUR hot-melt adhesives, MPU compounds and premium foam materials — MDI / TDI / PPDI / NDI systems, from Shore A30 soft grades to D80 rigid structural.
Five product families, from prepolymers to finished elastomers, soft seals to rigid wear parts. TDS available for every grade; custom targets for hardness, resilience and media resistance supported.
Cast polyurethane prepolymers (YC series): low exotherm and consistent part performance across 13 application areas — suited to medium & large structural and wear parts.
Graded T1–T5 by process complexity — precision standard seals to dynamic & specialty seals. Integrated material-to-part supply; custom molding available.
Moisture-reactive PU hot-melts: fast green strength, high final bond, heat & humidity resistant after cure — built for continuous lamination and assembly lines.
Chain-extension and crosslinking components matched to our prepolymer systems — they define hard-segment structure and final mechanicals. Supplied to customer formulations.
Two-component PU potting and structural bonding systems: thermal conductivity up to ≥1.2 W/(m·K), UL 94 V-0, Shore A30–D80, −40 to 110 ℃ continuous, 100% solids, RoHS compliant.
Millable PU rubber and high-performance foam systems, with non-standard formulation and small-batch sampling — damping, cushioning and lightweighting applications.
Products organized around real working conditions — every area has market-proven recommended grades with full specs. Click any tile.
Dedicated core-coating prepolymers, 300k+ press cycles.
Polishing & edging drive parts; face-coat and base-coat series.
Heat, extrusion and fatigue resistant — reliable in fracturing service.
Water seals for long emulsion immersion; supplied to leading seal makers.
Wear & corrosion resistance for coal/ore processing; scraper and equipment coating.
Seals for severe hydraulic/pneumatic duty; maintenance-free cartridge belts.
Low heat build-up, low noise, high load — OEM to world-class elevator brands.
Wear, tear and alkali resistant — 30,000 m³+ service life.
Paper, textile, printing, metalworking — wear & solvent resistant, low heat.
GF/YE series — thermally conductive, insulating, moisture-proof; water-clear options.
Apparel, hygiene and automotive nonwovens; flooring and profile wrapping.
Automotive pads, rail sleeper pads, tires and athletic soles.
61 grades and 62 TDS in one online selector — filter by hardness, chemistry and application, no back-and-forth with sales.
Covers every grade in production, dual search modes (by spec / by application), tiered staff & customer views. Download the TDS or fire an inquiry in one click.
TDS / SDS on file, ready when you are.
State your hardness, resilience and media targets — we formulate, ship samples and walk the pilot run with you.
We don't win on scale or price —
we win on formulation capability and technical response。
