What is the difference between a PU (Polyurethane) wheel and a rubber wheel?
PU (Polyurethane) wheel and rubber wheel are both popular types of wheels used in various applications. The main difference lies in their material composition and physical properties.
Polyurethane wheels are made of a thermoplastic material that offers a high level of mechanical and chemical properties. They are highly resistant to abrasion and are able to withstand heavy loads. They have a high coefficient of friction which gives them excellent traction on various surfaces. Polyurethane wheels also have a high level of elasticity which makes them more durable than rubber wheels.
Rubber wheels, on the other hand, are made of various types of elastomers such as natural and synthetic rubber. They are softer and offer a lower level of resistance to abrasion. Rubber wheels have a lower coefficient of friction which makes them less suitable for high traction applications. However, they are more flexible and offer better shock absorption than polyurethane wheels.
In summary, PU wheels are more durable and offer higher levels of traction than rubber wheels. Rubber wheels are more flexible and offer better shock absorption. The choice between the two would depend on the specific application and the required performance characteristics.
Rubber Roller Application
Rubber rollers are widely used in textile, printing and dyeingmachinery (rolling roller, printing machine rubber roller, coatingrubber roller, setting machine rubber roller etc.), papermaking,Plastic printing, packaging,industrial, wood, glass, steemetallurgy, tobacco, transportation and other equipment.
1) Base Roller Material &Thickness
We are using #45 steel,#201stainless steel #304stainless steeland 5# aluminum seamless pipe as the base roller.And we areadopting a reasonable thickness base roller according tocustomer's drawing.Some manufacturers will reduce thethickness ofthe steel pipe in order to get the priceadvantage.Such roller can't meet the standards.But we won'tdo that.
2) Rubber Material &Technology
Our rubber are allimported from Germany or the Japan andthen we mix them in our factory.The rubber coating technical weare using is winding technical. we cast the rubber on the baseroller layer by layer and then vulcanize it to make the greenrubber into mature rubber.While other manufacturers are usingsheet coating technical,and the rubber is cold in processing andwill cause adhesion problems easily.
