Features:   TPR material is a thermoplastic rubber material. It is a kind of thermoplastic soft rubber that has rubber elasticity and does not need vulcanization, and can be directly processed into molding(such as injection molding, extrusion, blow molding, etc.).  - Softer and more comfortable than rubber.  - Good reflective properties.  - Hardness between 50~70A, excellent elongation.  - Good bonding properties with certain glues, inks, etc., good process-ability for oil jet screen printing.  - Friendly for the environment, comply with ROHS,REACH.     Descriptions:  Manufacturing Precision: ±0.03mm;  Hardness: A 60-70;  Build Speed: 50-100mm/s;  Building TEMP: 230-260°C;  Heatbed TEMP: 60-80°C;  Melting Point TEMP: 160-180°C;  Hot Deformation TEMP: 80°C;  Tensile Strength: 7.1 Mpa;  Elongation Rate: >500%;  Tear Strength: 48KN/M;  Rebound elasticity : >50%;  Ross Flexing Fatigue: >200,000cycles;  Abrasion: 72mm³;  Density: 1g/cm³;  Accurate Diameter: 2.85mm;  Water Absorption Rate: 1%;     Package Included: 1 * 1KG TPR Filament ( Color Optional )
