Analysis of the top ten advantages of heavy duty polyurethan

Time:2018-09-10
 
 
 
Heavy-duty polyurethane plastics are widely used in Heavy Casters, and many manufacturers use this material for communication. It is a lightweight, impact resistant, abrasion resistant, corrosion resistant thermoplastic polyurethane elastomer manufactured using a cast production process.
 
 
 
Why did you choose this material? Because he has some unique characteristics:
 
 
 
1, good wear resistance, 5-8 times that of nitrile rubber;
 
 
 
2. Good bending strength and good elasticity;
 
 
 
3. Tensile strength and elongation at break are large;
Heavy Casters
 
 
4, strong tear resistance;
 
 
 
5, moderate temperature resistance (-50 ° C ~ 85 ° C) up to 120 ° C;
 
 
 
6, oil, water, mildew, solvent resistance;
 
 
 
7, good aging resistance;
 
 
 
8, the hardness can be adjusted in a wide range (Shore 15A ~ 98A);
 
 
 
9. The compression set is low;
 
 
 
10, cast iron Heavy Caster relatively speaking bearing capacity is relatively large.
 
 
 
Of course, this material also has certain limitations and cannot be used on some special types of Heavy Caster, but in general, this material can be widely used.
