Factory Machined Heat Insulation Spacer Insulation Washer
Factory machined heat insulation spacer insulation washer
Material analysis
insulation washer is made from high quality nylon raw material.
Nylon is a kind of engineering plastics used in comprehensive industries,has been applied almost every industrial field.The caprolactam monomer is first melted, and added catalyst, then poured it inside moulds at atmosphere pressure so as to shape in different castings, such as: rod, plate, tube.
Other casting Nylon:
Oil Nylon + Carbon (Black)
Oil Nylon added carbon, has the very compact and crystal structure, which is better than the general casting nylon in the performance of high mechanical strength, wear-resistance, anti-aging, UV resistance and so on. It is suitable for making the bearing and other wear mechanical parts.
Oil MC901(Blue)
This improved MC Nylon, has striking blue color, which is better than general PA6/PA66 in the performance of toughness, flexibility, fatigue-resistance and so on. It is the perfect material of gear, gear bar, transmission gear and so on.
MC Nylon + MSO2(Light black)
MC Nylon added MSO2 can remain the impact-resistance and fatigue-resistance of casting nylon, as well as it can improve the loading capacity and wear-resistance. It has a wide application in making gear, bearing, planet gear, seal circle and so on.
