1.The characteristics of the two are different:
1).The characteristics of ABS plastic
materials: ABS has excellent comprehensive physical and mechanical properties,
and good low-temperature impact resistance. Dimensional stability. Electrical
properties, abrasion resistance, chemical resistance, dyeability, finished
product processing and mechanical processing are better. ABS resin is resistant
to water, inorganic salts, alkalis and acids. It is insoluble in most alcohols
and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and
certain chlorinated hydrocarbons.
ABS resin has low heat distortion
temperature and is flammable and has poor heat resistance. The melting
temperature is 217~237℃, and the thermal decomposition temperature is above
250℃. Many modified ABS materials on the market today are mixed with nozzle
materials and recycled materials. As a result, the performance of customer
molded products is not very stable.
2).The characteristics of POM plastic
materials: POM plastic materials have high mechanical strength and rigidity;
the highest fatigue strength; environmental resistance, good resistance to
organic solvents; strong resistance to repeated impact; wide temperature range
(-40℃~120 ℃); good electrical properties; good recovery; self-lubricating, good
wear resistance; excellent dimensional stability.
2. The two applications are different:
1). Application of ABS plastic materials:
(1) Automobile interior and exterior
decoration: instrument panel, decorative pillar, instrument front cover,
grille, interior and exterior decorations;
(2) Business equipment casing and built-in
components: notebook/desktop computers, copiers, printers, plotters, monitors;
(3) Telecommunications, mobile phone
casings, accessories and smart cards (SIM cards).
2). Application of POM plastic materials:
(1) Pesticides: synthetic acetochlor,
butachlor and glyphosate, etc.;
(2) Coating: synthetic high-end automotive
paint;
(3) Resin: synthetic urea-formaldehyde resin, phenolic resin, polyacetal resin, melamine resin, ion exchange resin, etc. and various adhesives.
3. The performance of the two is different:
1).The performance of ABS plastic
materials: ABS engineering plastics are opaque and ivory-colored pellets, and
their products can be colored into colorful colors and have high gloss. The
relative density of ABS is about 1.05, and the water absorption rate is low.
ABS has a good combination with other materials, and is easy to be processed by
surface printing, coating and plating. The oxygen index of ABS is 18-20. It is
a flammable polymer. The flame is yellow with black smoke and a special
cinnamon smell.
2). The performance of POM plastic
materials: POM has good electrical insulation and is hardly affected by
temperature and humidity; dielectric constant and dielectric loss change little
in a wide range of temperature, humidity and frequency; arc resistance
Excellent and can be maintained at high temperatures.
POM is not resistant to strong acids and
oxidants, and has certain stability to olefinic and weak acids. POM has good
solvent resistance, can withstand hydrocarbons, alcohols, aldehydes, ethers,
gasoline, lubricating oil and weak alkalis, etc., and can maintain considerable
chemical stability at high temperatures. Low water absorption and good
dimensional stability.
