Hydrolysis Resistant Thermoplastic Polyester Elastomer
Product Description
A high-performance TPEE material with exceptional resistance to hydrolysis, designed for components operating in long-term, high-temperature, high-humidity, or water-contact environments.
Key Characteristics
1. Outstanding Hydrolysis Resistance: Minimal property degradation after long-term exposure to hot water/pressurized steam, significantly outlasting standard polyesters.
2. High Mechanical Strength & Toughness: Excellent tensile strength, flexural modulus, and impact resistance, especially at low temperatures.
3. Wide Service Temperature Range: Continuous use temperature from -40°C to +120°C (some grades up to 140°C+).Main Applications
(Note: Replaced from original automotive seals.) Automotive water pipe connectors, drive shaft bellows, hydraulic hoses, cable jacketing, seals for outdoor electronics, sports shoe components, industrial hoses.
Processing Method
Extrusion, Injection Molding (Processing methods are common, but temperature parameters differ).
Key Certs/Standards
Compliant with automotive OEM material specifications (e.g., TL, VW), UL recognition possible, RoHS, REACH.
Color
Natural (translucent to opaque), colorable.
Appearance
Uniform pellets or granules.
Packaging
20/25 kg/bag.

Processing Reference
(Note: Processing temps differ from TPV.) Drying: 100-120°C for 4-6 hours; Melt Temp: 200-240°C; Mold Temp: 30-70°C.
Key Notes
1. Control Melt Temp & Residence Time: Avoid excessively high temperatures and long residence times to prevent thermal degradation.
2. Mold Design: Requires good venting and proper cooling system.
