Beige Color Corrosion Resistant ABS Plastic Rods
Typical Applications and Components
Mechanical Manufacturing
Protective Covers and Frames: Machine tool operating panel frames and safety fences for automated equipment (welded/screwed ABS rods) protect operators from moving parts (impact-resistant) and offer lightweight design (50%-70% weight reduction).
Transmission Supports: Small gearbox cover mounting brackets and pulley adjustment levers (turned ABS rods) carry small to medium loads (≤50 kg) and are wear-resistant (resistance to minor friction).
Electronics and Electrical Equipment
Equipment Structural Components: Computer monitor stands and router housing mounting posts (milled ABS rods) offer high insulation (volume resistivity ≥10¹⁵ Ω·cm) and vibration resistance (resistance to equipment operation vibration).
Switch Panel Supports: Base reinforcement ribs for household and industrial electrical switches (flame-retardant ABS rods) offer high-temperature resistance (short-term 80°C) and flame retardancy (UL94 V-0 rating).
Architectural Decoration
Interior Decoration Profiles: Ceiling panel connectors and wall panel slots, with a smooth surface for easy installation (drillable and splicable), and stain resistance (wipes clean).
Display Stands and Signs: Transparent or translucent ABS rods (such as display cabinet frames) offer high gloss (enhancing visual appeal) and weather resistance (no yellowing for indoor use).
Industrial Equipment
Pipe and Tank Fittings: ABS rod flange connectors for small tanks (chemical-resistant grade), resistant to corrosion from weak acids and alkalines (such as dilute sulfuric acid and sodium hydroxide) (no swelling after long-term use).
Tool Handles: Screwdriver and wrench handles are coated (ABS rod injection molded parts) for non-slip performance (textured surface design) and impact resistance.
Frequently Asked Questions and Precautions
Hygroscopicity (Drying Required)
Although pure ABS rods have low hygroscopicity (equilibrium water absorption rate approximately 0.3%-0.5%), prolonged exposure to humid environments may cause surface microcracks or silver streaks during machining. Recommendation:
If the rods are stored in a humid environment (such as during the rainy season in southern China), it is recommended to dry them at 60-80°C for 2-4 hours before machining (ensuring a moisture content of less than 0.1%) to avoid surface bubbles during turning.
Risk of Low-Temperature Brittleness
The impact strength of ABS rods decreases significantly at temperatures below -5°C (potentially leading to brittle cracking). For applications in cold regions, select toughened and modified ABS rods (added with POE/EPDM, with a -20°C impact strength >15 kJ/m²).
Heat Resistance Limitations
The long-term operating temperature should not exceed 80°C (100°C for short periods). For high-temperature applications (such as near engines or steam pipes), use high-temperature-resistant modified ABS rods (e.g., by adding glass fiber or mineral fillers to increase the HDT to 100-120°C) or alternative materials (such as PA6 or PBT).
Surface Treatment and Bonding
ABS rods have a low surface energy (approximately 40-45 mN/m), resulting in poor adhesion to inks and adhesives. Flame treatment (high-temperature oxidation) or corona treatment is required to increase the surface energy to above 50 mN/m.
Epoxy resin glue or ABS-specific glue (such as Loctite 401) is recommended for bonding. Pre-drilling is required for mechanical connections (screws and bolts) to prevent cracking.
