ABS is a thermoplastic engineering plastic made by polymerizing three monomers:
A (Acrylonitrile): Provides hardness, chemical resistance, and temperature resistance
B (Butadiene): Provides toughness and impact resistance
S (styrene): Provides gloss, rigidity, and ease of processing
The combination of three properties makes ABS hard, tough, and rigid, with balanced comprehensive performance and friendly price, making it a benchmark for general engineering plastics.
Comprehensive highlights of ABS:
1. Excellent comprehensive mechanical performance, good rigidity, not easily deformed, and sufficient toughness. Its impact resistance is far superior to PP and PS, and it is not easy to crack during daily use.
2. The surface glossiness is extremely high, and the appearance is delicate, easy to color, spray, and electroplate. The products produced have high aesthetic value and a texture close to high-end shells.
3. Strong dimensional stability, low molding shrinkage rate, high product accuracy, not easy to warp, suitable for making appearance parts, structural parts, and precision shells.
4. Excellent processing performance, good fluidity, easy injection molding, no equipment selection, can produce thick and thin products, high yield rate, factory favorite.
5. Good chemical resistance, oil resistance, weak acid and alkali resistance, strong stability in daily environments, suitable for multiple scenarios such as home appliances, electronics, and daily necessities.
6. Highly modifiable and capable of adding fiberglass, flame retardant, anti-static, cold resistant, heat resistant, etc. With just one modification, it can adapt to various high end needs
Disadvantages of ABS:
1. Weather resistance: Ordinary ABS is generally resistant to ultraviolet rays and is prone to aging, yellowing, and brittleness outdoors. Therefore, UV resistance modification is necessary for outdoor use.
2. Poor transparency. Conventional ABS is opaque, and only PC or PMMA can be used for transparent parts.
3. High temperature resistance, limited long-term use temperature of about 70-90 ℃, high temperature environment is prone to softening and deformation.
4. It is not resistant to strong solvents and is prone to cracking and corrosion when encountering ester and ketone solvents.
5. Low temperature toughness generally decreases in extreme cold environments, and cold resistant products should use cold resistant ABS.
Typical application areas of ABS:
Home appliance industry: refrigerator panels, air conditioning enclosures, washing machine components, TV cases
Electronic appliances: chargers, keyboards, mice, routers, socket outlets
Automotive industry: interior parts, dashboard, door panels, decorative strips, pillars
Daily necessities: luggage, LEGO bricks, hangers, storage boxes, toys
Building materials hardware: door handles, switch panels, bathroom accessories
Industrial accessories: shell, bracket, gear, handle, structural components
