Performance
Exceptional Wear & Abrasion Resistance: Outperforms natural rubber and other elastomers, resisting mechanical wear, friction, and surface damage in high-cycle applications.
High Mechanical Strength: Excellent tensile strength, tear resistance, and load-bearing capacity, making it suitable for heavy-duty buffering and sealing tasks.
Wide Temperature Resistance: Operates reliably from -30°C to 80°C (short-term peak up to 100°C), maintaining elasticity and structural integrity in varying thermal environments.
Oil & Chemical Compatibility: Resistant to mineral oils, hydraulic fluids, and mild chemicals, preventing swelling, cracking, or degradation in industrial fluid systems.
Low Compression Set: Minimal permanent deformation under sustained pressure (≤25% at 70°C/22h), ensuring consistent sealing and buffering performance over time.
Shock & Vibration Damping: Excellent energy absorption properties, ideal for reducing noise, vibration, and harshness (NVH) in mechanical systems.
Non-Toxic & Food-Safe Option: Milk white formulation is free from harmful additives, with select grades approved for food and beverage processing equipment.
Application
Industrial Machinery: Seals, bushings, and buffer components for pumps, valves, and conveyor systems, providing wear-resistant performance in high-cycle operations.
Fluid & Hydraulic Systems: Cup seals and piston cups for hydraulic cylinders, pneumatic valves, and fluid transfer lines, ensuring leak-proof performance and resistance to hydraulic fluids.
Automotive & Transportation: Vibration dampers, suspension bushings, and sealing cups for vehicle systems, absorbing shocks and reducing noise while resisting oil and road chemicals.
Food & Beverage Processing: Food-safe PU cups for sealing and material handling in bottling, packaging, and processing equipment (FDA-compliant grades only).
Medical & Laboratory Equipment: Non-toxic sealing components for medical devices and lab instruments, where chemical resistance and biocompatibility are critical.
Consumer Goods: Buffer pads, sealing cups, and wear components for appliances, furniture, and sporting goods, offering durability and quiet operation
