Pom Sheet
Polyoxymethylene (POM) sheets excel with high tensile strength, low friction, and chemical resistance, setting them apart from many polymers. Their dimensional stability and ease of machining distinguish POM, making it ideal for precise engineering, gears, and components where durability, low wear, and chemical resilience are paramount.
Benefits of Pom Sheet
High stiffness
POM sheet has a high modulus of elasticity (2.8-3.5 GPa), which means it can withstand high loads without deforming or breaking. It also has a high flexural modulus (2.6-3 GPa), which means it can resist bending or twisting forces.
Low friction
POM sheet has a low coefficient of friction (0.1-0.35), which means it can slide smoothly over other surfaces without sticking or squeaking. It also has a low static friction (0.05-0.2), which means it can start moving easily without much force.
Excellent dimensional stability
POM sheet has a low thermal expansion coefficient (80-110 x 10^-6/K), which means it does not change its shape or size much when exposed to heat or cold. It also has a low moisture absorption (0.2-0.8%), which means it does not swell or shrink when exposed to water or humidity.
Good wear resistance
POM sheet has a high abrasion resistance (200-600 mg/1000 cycles), which means it can withstand rubbing or scraping without losing its surface quality or performance. It also has a high fatigue resistance (>10^7 cycles), which means it can endure repeated stress or strain without cracking or breaking.
Good chemical resistance
POM sheet has a good resistance to most solvents, oils, fuels and acids. It does not corrode or degrade easily when exposed to these substances.
Industrial Big Data
POM sheet has a good resistance to temperatures up to 130 °C. It does not melt or burn easily when exposed to heat or fire.

Types of Pom Sheet
Polyamide 6 (white)
This material has the most superior comprehensive properties, including mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. These characteristics, coupled with good electrical insulation and chemical resistance, make nylon 6 a "general-purpose" material for the manufacture of mechanical structural parts and maintainable parts.
Polyamide 66 (cream)
Compared with nylon 6, it has better mechanical strength, stiffness, heat resistance, wear resistance, and creep resistance, but its impact strength and mechanical shock absorption performance are reduced, which is very suitable for automatic lathe machining.
Polyamide 4.6 (reddish brown)
Compared with ordinary nylon, nylon 4.6 is characterized by strong rigidity retention, good creep resistance, and better heat aging resistance in a wider temperature range. Therefore, nylon 4.6 is used in the "higher temperature range" (80-150 °C) where nylon 6, nylon 66, POM and PET cannot meet the requirements in terms of stiffness, creep resistance, heat aging resistance, fatigue strength and wear resistance.
Polyamide 66+GF30 (black)
Compared with pure nylon 66, this nylon is reinforced with 30% glass fiber, and its heat resistance, strength, stiffness, creep resistance, dimensional stability, wear resistance and other properties are improved. Its maximum allowable use temperature is higher.
Polyamide 66+MOS2 (gray black)
This nylon is filled with molybdenum disulfide. Compared with nylon 66, its rigidity, hardness and dimensional stability are improved, but the impact strength is reduced. The grain forming effect of molybdenum disulfide improves the crystal structure, which improves the material's load-bearing and wear resistance.
This time our customers want us to process the POM sheet, the size of 800 * 900mm, an area of 0.72 square meters, the flatness requirement after processing is within 0.1mm. Due to the complexity of the texture, the amount of processing work is large, coupled with the possibility of bending and deformation of the POM plate during processing, a little inattention will not meet the flatness requirements.
At the beginning, we tried to process directly, but did not meet the flatness requirements; the second processing, we used vacuum suction cups to fix the plastic plate to prevent deformation during processing and damage to the workpiece, but still unsuccessful; the last attempt, we used heavy objects to flatten this plastic plate after processing, and finally met the flatness requirements.

Nylon
Nylon is another type of engineering thermoplastic that is used for precision parts that require high strength and toughness. Nylon has a higher impact strength and elongation than POM sheet, which means it can absorb more energy and stretch more before breaking. However, nylon has a lower stiffness and dimensional stability than POM sheet, which means it can deform or warp more easily. Nylon also has a higher moisture absorption and thermal expansion than POM sheet, which means it can swell or shrink more when exposed to water or heat. Nylon also has a lower chemical resistance and thermal resistance than POM sheet, which means it can corrode or degrade more easily when exposed to harsh substances or temperatures.
Polypropylene
Polypropylene is a type of thermoplastic that is used for general-purpose applications that require low cost and light weight. Polypropylene has a lower density and a lower melting point than POM sheet, which means it is lighter and easier to process. However, polypropylene has a lower stiffness and strength than POM sheet, which means it can break or deform more easily. Polypropylene also has a lower dimensional stability and wear resistance than POM sheet, which means it can change its shape or size more easily and lose its surface quality or performance more quickly. Polypropylene also has a lower chemical resistance and thermal resistance than POM sheet, which means it can corrode or degrade more easily when exposed to harsh substances or temperatures.
Polycarbonate
Polycarbonate is a type of thermoplastic that is used for applications that require high transparency and impact resistance. Polycarbonate has a higher transparency and a higher impact strength than POM sheet, which means it can transmit light and withstand shocks better. However, polycarbonate has a lower stiffness and hardness than POM sheet, which means it can scratch or dent more easily. Polycarbonate also has a lower dimensional stability and wear resistance than POM sheet, which means it can change its shape or size more easily and lose its surface quality or performance more quickly. Polycarbonate also has a lower chemical resistance and thermal resistance than POM sheet, which means it can corrode or degrade more easily when exposed to harsh substances or temperatures.
