Colored TPU & Modified TPU:
1. Colored TPU (Colored Thermoplastic Polyurethane) Colored TPU is a high-performance thermoplastic polyurethane elastomer featuring vibrant, customizable coloration while retaining TPU’s inherent core properties. It combines the flexibility of rubber, the mechanical strength of engineering plastics, and excellent color stability, making it a versatile material for aesthetic and functional applications across industries.
**Key Features**: – **Rich & Stable Color Options**: Offers a full spectrum of hues (including custom-matched colors) with exceptional resistance to fading, discoloration, and UV radiation, ensuring long-term color retention in harsh environments. – **Integrated Performance**: Maintains TPU’s signature attributes—superior elasticity, abrasion resistance, oil resistance, and low-temperature flexibility (down to -40°C depending on formulation)—without compromising color integrity. – **Eco-Friendly & Processable**: Free of heavy metals and harmful additives (compliant with RoHS, REACH standards); compatible with conventional processing methods such as injection molding, extrusion, blow molding, and 3D printing. **Typical Applications**: – Consumer Electronics: Colored phone cases, smartwatch straps, earbud covers, and cable jacketing. – Sport & Leisure: Vibrant shoe soles, fitness equipment grips, yoga mats, and waterproof apparel liners. – Automotive: Interior trim (e.g., steering wheel covers, door handles), colored airbag covers, and decorative seals. – Medical Devices: Disposable colored catheters, surgical instrument grips, and rehabilitation equipment components (meets biocompatibility standards like ISO 10993). #### 2. Modified TPU (Modified Thermoplastic Polyurethane) Modified TPU refers to TPU elastomers optimized through chemical modification (e.g., copolymerization, blending) or physical modification (e.g., filler addition, reinforcement) to enhance specific performance characteristics beyond standard TPU. Tailored to address industry-specific challenges, modified TPU expands the material’s application boundaries in high-demand scenarios. **Key Modification Directions & Advantages**: | Modification Type | Core Improvements | |————————-|———————————————————————————-| | Flame-Retardant Modified | Achieves UL94 V0/V1 flame rating; low smoke emission; suitable for electrical/electronic components and automotive interiors. | | Reinforced Modified | Enhanced tensile strength (up to 80 MPa), rigidity, and dimensional stability via glass fiber or mineral filling; ideal for structural parts. | | Wear-Resistant Modified | Ultra-low coefficient of friction (COF < 0.2) and improved abrasion resistance (10x higher than standard TPU); used in gears, rollers, and industrial hoses. | | Hydrophilic/Hydrophobic Modified | Customized water absorption properties—hydrophilic grades for medical dressings, hydrophobic grades for waterproof seals. | | High-Temperature Resistant Modified | Continuous service temperature up to 120°C; retains elasticity under thermal stress; suitable for engine components and high-temperature gaskets. | | Antimicrobial Modified | Inhibits growth of bacteria (e.g., E. coli, Staphylococcus aureus) and fungi; meets ISO 22196 standards for medical and daily-use products. | **Typical Applications**: – Industrial Engineering: Modified TPU rollers for conveyor systems, wear-resistant gaskets for hydraulic equipment, and flame-retardant cable insulation. – Robotics & Automation: High-strength modified TPU joints for humanoid robots, flexible yet rigid structural components, and antimicrobial gripper pads. – Aerospace & Automotive: Heat-resistant TPU seals for aircraft engines, flame-retardant interior parts, and reinforced TPU bumpers. – Medical & Healthcare: Antimicrobial TPU catheters, hydrophilic wound dressings, and high-purity modified TPU for implantable devices (compliant with FDA standards). — ### Supplementary Notes for Technical Accuracy: 1. **Terminology Consistency**: – “TPU” is universally accepted (no need for full spelling after first mention). – Modified TPU types are named by their core function (e.g., “flame-retardant modified TPU” instead of “FR-TPU” unless specified by industry conventions). 2. **Performance Metrics**: – All data (e.g., temperature range, tensile strength) are industry-typical values; adjust based on specific formulations. 3. **Compliance Standards**: – Mentioning international standards (RoHS, REACH, ISO) enhances credibility for global markets.
