Engineered for extreme chemical environments, our Chemical Resistance UHMEPE Engineering Plastic (Ultra-High Molecular Weight Ethylene Propylene Engineering Plastic) combines exceptional chemical inertness with superior wear resistance, setting a new standard for harsh industrial applications. With a molecular weight exceeding 3.5 million g/mol, this thermoplastic offers unmatched resistance to corrosive media, abrasion, and low-temperature brittleness, making it ideal for components in chemical processing, marine engineering, and food/pharmaceutical industries. Its non-absorptive surface and low friction coefficient redefine performance in environments where traditional plastics fail.
Exceptional Chemical Inertness
Broad Chemical Resistance: Unaffected by acids (HCl, H2SO4 up to 98%), alkalis (NaOH up to 50%), and organic solvents (toluene, acetone), with weight loss ≤0.1% after 1000h immersion (ASTM D543).
Non-Polar Structure: Linear molecular chain structure resists hydrogen bonding with polar/non-polar chemicals, outperforming PTFE in low-temperature chemical resistance (-196°C to 80°C operational range).
Superior Mechanical Performance
High Wear Resistance: Abrasion loss ≤5 mm³/1000 cycles (ASTM D4060), 15x better than HDPE and 3x better than PTFE, ideal for slurry transport and abrasive environments.
Impact Resistance: Unnotched impact strength ≥400 J/m (ASTM D256) at -40°C, maintaining ductility in cryogenic applications (e.g., liquefied gas processing).
Low Friction & Self-Lubricating
Coefficient of Friction: 0.1-0.3 (ASTM D1894), reducing energy consumption in conveyor systems and pump components without additional lubrication.
Non-Stick Surface: Surface energy ≤30 mN/m prevents material adhesion (e.g., sticky slurries, food particles), minimizing downtime for cleaning (FDA 21 CFR 177.1520 compliant for food contact).
Processability & Design Flexibility
Custom Molding Options: Available in rods, sheets, and custom-molded parts via compression/ram extrusion, with dimensional stability (linear expansion coefficient 11x10⁻⁵/°C) for precision components.
Lightweight: Density 0.93-0.95 g/cm³, 50% lighter than steel and 20% lighter than PEEK, reducing structural load in marine and aerospace applications.
Chemical Processing
Pump Components: Impellers, seals, and valve seats resistant to aggressive chemicals in petrochemical refineries (NACE MR0175 compliant for sour gas environments).
Pipe Linings: Non-corrosive liners for transporting hydrochloric acid, sodium hydroxide, and organic solvents, extending service life by 3x compared to rubber-lined pipes.
Marine Engineering
Rudder Bearings & Propeller Bushings: Withstands saltwater corrosion (ASTM B117, 5000h salt spray) and low-friction operation in ship propulsion systems.
Offshore Platforms: Wear-resistant guides for mooring systems, resisting abrasion from sand-laden seawater (ISO 12944 C5-M corrosion category).
Food & Pharmaceutical
Conveyor Belts & Chute Liners: FDA-compliant surface prevents product contamination, ideal for processing sticky foods (e.g., confectionery, meat) and pharmaceutical powders.
Medical Components: Non-toxic, non-absorptive material for drug manufacturing equipment (USP Class VI biocompatibility certified).
Material Science Leadership
Proprietary Molecular Modification: Patented cross-linking technology (US Patent 11,685,432) increases chemical resistance by 20% and wear life by 40% compared to standard UHMEPE.
Advanced Testing Capabilities: In-house FTIR spectroscopy and SEM analysis ensure molecular weight distribution uniformity (Mw/Mn ≤2.5), validated by third-party labs (SGS, Intertek).
Quality Assurance
100% Traceability: Each batch tracked from raw material (resin purity ≥99.8%) to finished product, with Mill Test Reports including chemical resistance, impact strength, and dimensional data.
ISO Compliance: Manufactured under ISO 9001:2015 and ISO 14001:2015, with products certified to EU REACH, RoHS 3.0, and NSF 61 for potable water applications.
Custom Solutions
Tailored Grades: Offer anti-static (surface resistivity 10⁶-10⁹ Ω), conductive (10³-10⁶ Ω), and flame-retardant (UL 94 V-0) variants for specialized industrial needs (MOQ 100kg).
Engineering Support: In-house CAD/CAM team provides design optimization for stress analysis (FEA) and mold flow simulation, reducing prototype iteration time by 50%.
Global Supply Network
Rapid Prototyping: 7-day turnaround for sample parts (3D printing + CNC machining), 15-day lead time for production orders (500kg+), with warehouses in North America, EU, and APAC regions.
Sustainability Commitment: 30% post-industrial recycled content options and 100% recyclable packaging, aligned with circular economy principles (CEC 2021 compliant).
