The difference between ndustrial PP Casters and Elastic rubb

Time:2018-09-05
 
 
 
 Before the Second World War, rubber has always been the material of choice for the wheel manufacturing industry, because the material is naturally easy to obtain, low cost and widely favored by countries all over the world. However, during the Second World War, rubber and other materials were in short supply. After repeated research and exploration, people finally found a more cost-effective material, Industrial PP Casters. The wide application of Industrial PP Casters material not only relieves the shortage of rubber and other materials, but also compensates for some defects of rubber. Do you know the difference and difference between the two?
 
Wheel hardness and resilience
Elastic rubber Casters usually have a hardness of 67-75 degrees and a relatively low hardness;
Industrial PP Casters have a hardness of 83-95 degrees. Under the premise of ensuring safety, Industrial PP Casters not only has large bearing capacity, small rolling resistance, but also guarantees a certain buffering capacity. More importantly, the wheel hardness and resilience of Industrial PP Casters can be adjusted according to customer requirements and usage environment.
Industrial PP Casters
Raw material
Elastic rubber Casters: easy to pollute, low production efficiency, raw materials can be doped with recycled materials, there will be odor;
Industrial PP Casters: The tread is more demanding, using raw materials, no odor, and can not be mixed with recycled materials.
 
Ground mark
Elastic rubber Casters are easy to leave a mark of carbon black on the ground during use;
The basic chemical composition of Industrial PP Casters determines that Industrial PP Casters will not leave marks on the ground, and even brightly colored wheels will not leave any traces of coloring agents on the ground.
 
Aging resistance
When rubber is exposed to organic solvents for a long time, it is prone to swelling, and the tear strength and the ability to resist collapse and blockage are also weakened;
Industrial PP Casters maintains its properties and will not corrode even after prolonged exposure to organic solvents.
 
Wheel load
The heavy rubber load is about 160-230kg, and the crack resistance and tear resistance are poor;
Industrial PP Casters have about twice the load carrying capacity of Elastic rubber Casters, with excellent resistance to crack growth, tearing and chipping resistance. Even after 7-8 years, the performance is still good and has good resistance. Grinding.
Elastic rubber Casters
In the current industry, compared to Elastic rubber Casters, plastic cores such as Industrial PP Casters and iron core Industrial PP Casters have obvious properties in terms of load carrying capacity, wear resistance, tear resistance, cutting resistance and rolling resistance. The advantages, excellent material quality, high cost performance, widely favored by consumers, gradually replaced the position of Elastic rubber Casters.
