Differences between ABS plastic and POM:
1. The characteristics of the two are different:
1. Characteristics of ABS plastic: ABS has excellent composite physical and mechanical functions and particularly good low temperature impact resistance. Dimensional stability. Electrical performance, abrasion resistance, chemical resistance, dyeing, finished product processing and mechanical processing are all good. ABS resin has the ability to resist water, inorganic salts, alkalis and acids, and is insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons.
ABS resin has a low heat distortion temperature, is flammable, and has poor heat resistance. The melting temperature is 217~237°C, and the thermal decomposition temperature is above 250°C.
2. The characteristics of POM plastics: POM plastics have high mechanical strength and rigidity; environmental resistance, excellent resistance to organic solvents; strong ability to resist repeated impact; wide temperature range (-40 ° C ~ 120 ° C); Very good electrical function; fast recovery; self-lubricating, good wear resistance.
The two uses are different:
1. The use of ABS plastic:
(1) Interior and exterior decoration of cars: instrument panels, decorative pillars, instrument front covers, grilles, interior and exterior decoration parts;
(2) Commercial equipment chassis and built-in components: notebook/desktop computers, copiers, printers, plotters, monitors;
(3) Telecommunications, mobile phone cases, accessories and smart cards (SIM cards).
2. The use of POM plastic:
(1) Pesticides: composition of acetochlor, butachlor and glyphosate;
(2) Coatings: composed of high-end car coatings;
(3) Resin: composed of urea-formaldehyde resin, phenolic resin, polyacetal resin, melamine resin, ion exchange resin, etc., and various adhesives.
The performance of the two is different:
1. The function of ABS plastic: ABS engineering plastic is an opaque ivory-colored pellet, and its products can be colored into colorful 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 it is easy to surface print, coat and plate. ABS has an oxygen index of 18-20 and is a flammable polymer. The flame is yellow with black smoke and has a characteristic cinnamon smell.
2. The performance of POM plastics: POM has excellent electrical insulation and is almost not affected by temperature and humidity; the dielectric constant and dielectric loss change little in a wide range of temperature, humidity and frequency; arc resistance is extremely Well, able to hold on to the heat.
