POM Rod Vs.PEEK Rod

POM rods and PEEK rods are polymer thermoplastic engineering plastic profiles, with high surface hardness and mechanical strength, good lathe turning performance and excellent wear resistance, are indispensable in the field of mechanical production of a good choice of materials;

Comparative analysis of POM rods and PEEK rods:

Commonality: both materials are polymer thermoplastic engineering plastic profiles, with high surface hardness and mechanical strength, with good lathe turning performance and excellent wear resistance, are indispensable in the field of mechanical production of a good choice of materials;

Difference:

1, Temperature resistance, PEEK temperature in 250 degrees or so, and POM temperature resistance is only 80-100 degrees or so, even if the modified POM rods temperature resistance is up to 110 degrees or so, so in the temperature resistance PEEK has POM can not reach the advantage;

2, Self-lubricating, although both materials are defined as wear-resistant materials, but wear-resistant is also incidental, especially the High temperature/high load/high pressure working environment, PEEK rods are capable of a variety of extremely harsh environments, and the surface phase out of a good and stable performance, which is incomparable to POM rods;

3, Price, the price of PEEK is much higher than the POM whole dozens of times in the processing and production, the cost will be greatly increased;

4, In terms of flame retardant grade, PEEK rods themselves with good Flame retardant properties, is 1.45mm thick test sample, its flame retardant coefficient is also as high as UL94-V0 level, and POM rods as a formaldehyde resin, itself does not bring flame retardant, easy to produce combustion in the event of fire, and the flame presents a light blue, not easy to find, this is for the use of the customer base is a potential pitfalls;

5, In the hydrolysis of PEEK rods can be more than 100 degrees of high temperature steam In terms of hydrolysis, PEEK rods can be repeated in more than 100 degrees of high-temperature steam use, while POM rods in the hydrolysis resistance is only limited to room temperature conditions, and the performance is not stable enough;
