|
 |
| Polyshape Nylon6 Rods, and Machinery parts are characterized by a combination of high strength, toughness and abrasion resistances. Polyshape products replace metals in various engineering applications as they are manufactured by Extrusion Technique and therefore they have excellent physical and mechanical properties, some of the outstanding characteristics are as follows |
| |
• Reduction in weight
• Self lubricating economy
• Shock resistance
• Improved dimensional stability
• Vibration damping performance
• High wear and abrasion resistance
• Noise reduction
• High service temperature
• High tensile and compressive Strengths Machining
|
|
