Product details
Flexible PU Plastic Rod for Bending Applications
Product Overview
Flexible PU Plastic Rod is a high-performance engineering plastic material that combines the elasticity of polyurethane (PU) with the durability of plastic. It is widely used in industries such as industry, medical treatment, and consumer electronics. Its core properties include high flexibility, wear resistance, chemical corrosion resistance, and excellent mechanical strength. It is suitable for scenarios that require both flexibility and structural stability.
Physical properties
| Property | Value range |
| Tensile strength | 20 - 50 MPa |
| Elongation at break | 200% - 600% |
| Abrasion resistance | Better than PVC and rubber |
| Temperature range | -40℃ to +80℃ (can withstand 120℃ for a short time) |
| Water absorption | <0.1% |
Chemical properties
Chemical resistance: Resistant to oils, weak acids and weak alkalis, insoluble in common organic solvents (such as gasoline, alcohol).
UV resistance: Adding UV stabilizers, it is not easy to yellow when used outdoors.
Flame retardant: Optional flame retardant formula (compliant with UL94 V-0 standard).
Product advantages
Perfect balance of flexibility and strength
Compared with traditional plastics (such as PVC, PE), PU rods have high flexibility and impact resistance, and can be bent without breaking easily.
Suitable for dynamic load scenarios (such as conveyor belts, shock-absorbing components).
Durability and long life
The wear resistance is 3-5 times that of rubber, and the service life is more than 5 years (depending on the use environment).
Excellent anti-aging performance, long-term exposure to ultraviolet rays or humid environments can still maintain stable performance.
Environmental protection and safety
Halogen-free, low VOC emissions, in line with RoHS and REACH environmental standards.
FDA certified (some models), can be used in food contact or medical fields.
Convenient processing
Supports cutting, drilling, hot melt welding and other processing methods, and can customize complex shapes.
It has strong compatibility with other materials such as metals and plastics, and is suitable for secondary molding.
Application scenarios
Industrial field
Mechanical parts: wear-resistant bushings, gears, bearing isolators.
Automation equipment: flexible connectors, cable protective sleeves.
Conveying system: conveyor belt rollers, shockproof gaskets.
Consumer electronics
Wearable devices: watch straps, mobile phone holder flexible connectors.
Earphone accessories: earplug shells, wire protective sleeves.
Medical and health
Orthopedic equipment: rehabilitation braces, medical catheter outer coating.
Prosthetic parts: high elastic joint connectors.
Automobile and transportation
Automotive interior: anti-slip mats, sealing strips.
Rail transportation: shock-absorbing buffer blocks, cable fixings.
Other fields
Sports goods: yoga mats, sports equipment handles.
Household goods: anti-slip foot pads, door and window sealing strips.
FAQ
Q1: Is PU rod resistant to oil and chemicals?
A: Yes, it can withstand mineral oil, vegetable oil and weak acid and alkali, but long-term contact with strong solvents (such as acetone) is not recommended.
Q2: How to choose the right hardness?
A:
60A-75A: High flexibility, used for shock pads and seals.
80A-90A: Balanced flexibility and support, used for industrial rollers.
95A: Close to plastic hardness, used for structural parts.
Q3: Does it support small batch customization?
A: Yes.
