Introduction
TPEE is produced by 1.4-butanediol, polytetra-methylene glycol, and DMT or PTA going through copolymerization condensation. It also can be made into thermoplastic polyester elastomer composites through kneading procedure. TPEE possesses a number of excellent features and is widely used in electrical appliances, IT, and automotive industries.
Thermoplastic Polyester Elastomer (TPEE): Overview and Key Properties
| Category | Details |
|---|---|
| Chemical Structure | Block copolymer of hard (PBT) and soft (polyether/glycol) segments |
| Common Names | TPEE, TPC-ET, COPE (Copolyester Elastomer) |
| Key Features | Combines rubber-like elasticity with thermoplastic processability |
Physical & Mechanical Properties
| Property | Value/Range |
|---|---|
| Hardness (Shore D) | 30D–82D |
| Tensile Strength | 20–50 MPa |
| Elongation at Break | 300–700% |
| Melting Point | 150–220°C (302–428°F) |
| Density | 1.10–1.30 g/cm³ |
| Flexural Modulus | 50–1.500 MPa |
Thermal & Chemical Resistance
| Property | Performance |
|---|---|
| Continuous Use Temp. | –40°C to 150°C (–40°F to 302°F) |
| UV Resistance | Moderate (requires additives) |
| Chemical Resistance | Resists oils, fuels, polar solvents; poor vs. strong acids/bases |
Processing Methods
| Method | Conditions |
|---|---|
| Injection Molding | 190–250°C, drying required (≤0.05% moisture) |
| Extrusion | 180–230°C |
| Blow Molding | Suitable for hollow parts |
Applications by Industry
| Industry | Typical Uses |
|---|---|
| Automotive | CVJ boots, airbag covers, vibration dampers |
| Consumer Goods | Sports equipment, shoe soles, wearables |
| Industrial | Seals, hoses, conveyor belts |
| Medical | Tubing, catheter components (medical-grade) |
Advantages vs. Limitations
| Advantages | Limitations |
|---|---|
| High fatigue resistance | Higher cost than TPE-S or TPO |
| Excellent rebound elasticity | Limited hydrolysis resistance |
| Recyclable/reprocessable | Requires drying before processing |
Comparison with Other Thermoplastic Elastomers
| Material | TPEE vs. Alternatives |
|---|---|
| TPU | Better heat resistance, lower abrasion |
| TPO | More flexible, lower cost |
| TPV | Superior chemical resistance, less elastic |
Summary
TPEE excels in applications demanding elasticity, heat resistance, and mechanical durability. Its versatility spans automotive, industrial, and consumer sectors, though cost and hydrolysis sensitivity require careful material selection. Innovations focus on eco-friendly formulations and expanded medical uses.
