Features

 

High mechanical strength

Tensile strength can be up 50.5MPa . close to metal properties . and only a tiny change on mechanical strength even working temperature has a large change .

 

Good wear resistant

Wear resistant strength still keeps 35MPa or so even item is put 10 J variable load . it is best compared to items that with PA,ABS,HPVC,PS,PC

 

Resistant impact

POM has good impact resistance but inferior to ABS and PC , Impact performance will be down 90% or so if there is breaking on or in product .

 

Self-lubricant

POM parts with F4 , C ,MoS2 ,PE and lubricant elements that improve self-lubricant performance .

 

Stability in dimensions

POM part with good tensile strength and hardness that not easy to be deformed and broken .

 

Resistant Organic solvent

POM parts are resistant for hydrocarbon ,alcohol ,ether ,aldehyde , gasoline ,lubricant and Weak Alkalis .

 

Small creep properties

Creep property rate is 2.3% or so in 20℃,21MPa,3000h . and nearly not be effected by temperature

 

Good insulation

POM items nearly not be effected by temperature and humidity on insulation . insulation is related with the thickness of items , eg when thickness is 0.127mm insulation is 82.7kV/mm,thickness is 1.88mmi insulation is 23.6kV/mm

 

 

In addition to plastic spur gear , we make more plastic gears as well like bevel gear ,duplicate gear ,herringbone gear etc which are used to various fields . customized designs are also available for us . welcome you to contact us for more information about plastic gears .
