Can flame retardant ABs plastic be ultrasonically welded?

The use of flame retardant ABs plastics includes car accessories, radio cases, phone handles, high-strength tools, typewriter keyboards, entertainment vehicles such as golf carts and jet skis.

Flame retardant ABs plastic has better comprehensive performance, higher impact strength, chemical stability, and good electrical properties. It has good weldability with 372 plexiglass, made of two-color plastic parts, and can be chrome-plated and spray-painted.

Suitable for making general mechanical parts, wear-resistant parts, transmission parts and telecommunication parts. Amorphous materials, medium fluidity, high moisture absorption, must be fully dried, plastic parts requiring a glossy surface must be preheated and dried for 80-90 degrees for 3 hours.

To solve the problem of water entrapment, it is necessary to improve the fluidity of the material, adopt high material temperature, high mold temperature, or change the water level. For example, if heat-resistant or flame-retardant materials are formed, plastic decomposition products will remain on the surface of the mold after 3-7 days of production, which will cause the surface of the mold to be shiny, and the mold must be cleaned in time. At the same time, the exhaust surface of the mold must be increased.

Flame retardant ABs plastic

ABS resin is currently a large-volume, widely used polymer. It unifies the various properties of PS, SAN, and BS organically, and has excellent mechanical properties of toughness, rigidity, and rigid phase balance.

ABS engineering plastics are generally opaque, with a light ivory color, non-toxic, and tasteless, with both tough, hard, and rigid characteristics. They burn slowly, the flame is yellow, and there is black smoke. After burning, the plastic softens and burns, and emits special Smell of cinnamon, but no dripping.

ABS engineering plastics have excellent comprehensive properties, excellent impact strength, good dimensional stability, electrical properties, abrasion resistance, chemical resistance, dyeing properties, and good molding and machining.

ABS resin is resistant to water, inorganic salts, alkalis and acids. It is insoluble in most alcohol and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons.
