TR90 is a high-performance transparent polyamide (chemically designated as amorphous nylon 12) . It combines optical clarity with exceptional mechanical resilience and chemical resistance, making it a preferred material for precision applications requiring both aesthetics and functionality.
Key Properties
Optical Clarity
• Achieves >90% light transmittance with UV resistance, suitable for optical components.
01
Mechanical Performance
• High tensile modulus (1,600 MPa) and ball indentation hardness (90 MPa).
• Excellent fatigue resistance and impact toughness, even at low temperatures.
02
Thermal Stability
• Glass transition temperature of 155°C.
• Dimensional stability under thermal stress.
03
Low Moisture Absorption
• Absorption rate ~0.1–0.3%, ensuring minimal swelling in humid environments.
04
Chemical Resistance
• Resistant to oils, solvents, hydrolysis, and stress cracking.
05
Primary Applications
- Eyewear Frames: Lightweight, flexible, and memory-like properties for sports/safety glasses.
- Medical/Consumer Goods: Toothbrushes, filter bowls, and optical fiber casings.
- Automotive: Sensor covers, fluid reservoirs, and engine components.
- Industrial: Connectors and housings requiring chemical resistance
- Consumer Electronics: Transparent covers for VR headsets, smartwatch casings, and anti-fracture lenses (replacing glass/PC)
- TR90's unique blend of transparency, elasticity, and durability drives innovation in optics, medical, and consumer sectors, outperforming conventional plastics in dynamic-load environments
