(MC nylon pulley) is the latest products developed by Guangzhou Engineering plastics industries Co., Ltd, which is mainly used in large hoist as the passive ture, to lighten the weight of itself and prolong the longevity of cable.
Performance:Uv resistance, corrosion-resistance, self-lubricated,ect.
PA66 Sheave / MC Nylon Sheave (Natural/white)
MC Nylon,means Monomer Casting 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. The molecule weight of MC Nylon can reach 70,000-100,000/mol. Its mechanical properties are much higher than other nylon materials. MC Nylon plays a more and more important role in the material list recommended by our country.
Since the end of 1980s, Guangzhou Engineering Plastics Industries Co., Ltd has devoting herself on developing the technology of MC Nylon modification, greatly extended the applications in different industries. Basing on the MC Nylon, reinforced with variety of additives during the reaction, such as lubricant, molybdenum disulfide, graphite glass fiber, carbon fiber etc, to improve the properties, higher performance of wear-resistance, corrosion-resistance,
self-lubrication, vibration-absorption, noise-absorption. At the same time, as the technics and structure of the moulds is quite simple, so that it can be manufactured in lower cost, becomes the ideal substitutes of bronze, stainless steel, Babbitt alloy , PTFE and so on.
Applied instances of MC nylonI ( 1 )
MC nylon is mainly applied in the field of mechanical engineering, chemical engineering, electric/electronic, auto industry etc, to be made bearing & wear parts and structural parts instead of copper, tin, alloy and stainless steel. Because of the excellent inherent properties ,MC nylon is widely used in different industries, such as: mining, metallurgy, petroleum, construction, textile, pulp & paper, shipbuilding, water and electricity project, environmental protection and water treatment, ocean developing, war industry and so on. It produces the distinct benefit of economy and society.
The profile shapes of MC nylon, such as pipe, tube and plate can be manufactured into the four wear and friction components: gear, sheave, bearing and roller, as well as different kinds of structural component, such as: mechanical seal circle, guide plate, scraper etc.
