Top 10 Advantages and Disadvantages of Typical Wear-Resistant Plastics

August 09, 2024

The following plastics editor will summarize the advantages and disadvantages of ten typical wear-resistant plastics:

Material	Advantages	Disadvantages
PTFE	Extremely low coefficient of friction, high chemical resistance, cold and high temperature resistance 260+, wide range of operating temperatures, flame retardant	Lower mechanical strength and higher coefficient of thermal expansion make it unsuitable for applications requiring high dimensional stability
UHMWPE	Very high abrasion resistance, low specific gravity, high chemical resistance, most abrasion resistant plastic, especially wet abrasion resistant	Poor heat resistance, low mechanical strength and rigidity, heat resistant below 80 degrees Celsius
PEEK	High strength and rigidity, high temperature resistant up to 330+, weather resistant, chemically resistant, flame retardant	Very high cost, difficult to process
PI	Very high heat resistance, heat resistant 350+, chemical resistant, high strength and rigidity, flame retardant	Very high cost, complex processing
POM	Good abrasion resistance and self-lubrication, high rigidity and strength, medium chemical resistance, cheapest, well-processed abrasion-resistant material, cost-effective	Average heat resistance, formaldehyde gas release at high temperatures, flammable
POK	Good wear resistance and self-lubrication, close to POM, low moisture absorption, chemical resistance equal to PA, fatigue resistance, wear-resistant under certain conditions better than POM	Medium heat resistance, close to Pa6, cost is higher than POM, processing temperature is narrow, easy to carbonize, not cost-effective
Pa66	Good wear resistance and self-lubrication, high strength and rigidity, good heat resistance, easy processing, wear modification of the most widely used, good chemical resistance	Strong hygroscopicity, affecting dimensional stability, performance degradation in wet environment.
PA46	Excellent wear resistance and self-lubrication, high strength and rigidity, heat resistance 280+, good chemical resistance	Higher cost, nylon general disease, strong moisture absorption, affecting dimensional stability
PPS	High temperature 250+, good abrasion resistance, strong chemical resistance, inch stability, flame retardant	Cost-effective in high temperature materials, high processing temperature
LCP	High strength and rigidity, suitable for high temperature 280+, strong dimensional stability, suitable for precision parts, strong chemical resistance, flame retardant	Higher cost, high processing technology requirements

Summarizing

PTFE and UHMWPE are the best performers in terms of coefficient of friction and self-lubrication, but with lower mechanical strength and extremely high wear resistance requirements first! But it also depends on the object of friction.

POM is excellent in terms of wear resistance and self-lubrication, very cost-effective and suitable for most gear and transmission applications.

PA66 is excellent in wear resistance and self-lubrication, moderately priced, wear modified to cover the widest range of applications.

PEEK, PI has high wear resistance, weather resistance, heat resistance and chemical resistance, suitable for working conditions appear temperature 300 + applications, but the cost is very high.

POK, excellent performance in wear resistance and lubrication, a combination of PA + POM performance, moderate cost, but the processing temperature is narrow, the application is limited.

LCP, PPS, PA46 has excellent mechanical properties and heat resistance, heat 250-290 wear-resistant applications around the choice, but the cost is high.
