ABS safety helmet ABS implications

The ABS helmet means that the material of the helmet is made of ABS engineering plastic. ABS helmets have high impact resistance and puncture resistance. Suitable for electric power, chemical industry, petroleum, construction, forestry, port, metallurgy and other industries.

ABS resin is currently the most productive and most widely used polymer. It integrates the various properties of PS, SAN, and BS organically. It combines tough, rigid and rigid mechanical properties. ABS is a terpolymer of acrylonitrile, butadiene, and styrene, A represents acrylonitrile, B represents butadiene, and S represents styrene.

ABS engineering plastics are generally opaque, the appearance of light ivory, non-toxic, odorless, both tough, hard, rigid characteristics, slow combustion, flame yellow, black smoke, burning plastic softened, charred, issued a special The smell of cinnamon, but no molten dripping phenomenon.

ABS engineering plastics have excellent comprehensive properties, excellent impact strength, good dimensional stability, electrical properties, abrasion resistance, chemical resistance, dyeability, and good molding and machining. ABS resin is resistant to water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, and easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons.

1. Amorphous materials, medium flow, large moisture absorption, must be fully dry, the surface of the plastic parts required to be shiny and preheated dry 80-90 degrees for 3 hours.
2. It is advisable to take high material temperature and high mold temperature, but the material temperature is too high and easy to decompose (decomposition temperature is >270 degrees). For high precision plastic parts, the mold temperature should take 50-60 degrees, high gloss, resistance to Thermoplastics, mold temperature should take 60-80 degrees.
3. If you need to solve the water mark, you need to improve the fluidity of the material, take a high material temperature, high mold temperature, or change the water level and other methods.
4. Such as the formation of heat-resistant grade or flame-retardant material, 3-7 days after the mold surface will remain plastic decomposition products, resulting in shiny mold surface, the need to clean the mold in a timely manner, while the mold surface needs to increase the exhaust position.
