Chemical-resistant modified plastic PPS GF40 for Automotive

Lisu Technology's modified plastic granules, PPS GF40 (40% glass fiber reinforced polyphenylene sulfide), possess the following characteristics:

I. Core Material Characteristics

1. Ultra-high heat resistance: Long-term continuous operating temperature 200~240℃, heat distortion temperature exceeding 260℃, capable of withstanding continuous high-temperature environments such as engines, reflow soldering, and industrial high-temperature equipment without deformation or softening at high temperatures.

2. Excellent corrosion resistance and media resistance: Resistant to engine oil, antifreeze, fuel, acids, alkalis, and various organic solvents; does not swell or crack after long-term contact with engine compartment chemical media and industrial corrosive fluids; extremely low water absorption and long-term dimensional stability.

3. High strength and low creep: With the addition of 40% alkali-free glass fiber reinforcement, tensile, bending, and impact strength are significantly improved; it does not deform under high temperature and pressure, making it suitable for load-bearing components such as gears, pump housings, and gearbox structural parts. 4. Natural Flame Retardant and Insulating Material
The substrate itself is UL94 V-0 halogen-free flame retardant, with stable dielectric properties. It provides insulation without breakdown in high and low temperature environments, making it suitable for high-voltage connectors, relays, coil bobbins, and other electronic and electrical components.

5. Wear-Resistant and Self-Lubricating
Low coefficient of friction, wear-resistant, requiring no additional lubrication for manufacturing gears, bearings, and valve plates, with minimal wear over long-term operation.

6. Precision Molding with Low Warpage
Low molding shrinkage and high dimensional accuracy, suitable for small precision structural components such as sensor housings, automotive lamp bases, and precision connectors.

II. Applications Across All Fields

1. Automotive Industry (High-Temperature Corrosive Environment in Engine Compartment)

Engine peripheral brackets/covers, cooling system water pump housings, thermostat housings, gearbox structural components, automotive sensor housings, automotive lamp bases, automotive high-voltage connectors.

2. Electronics and Electrical Industry (Flame Retardant, Insulating, and Solder-Resistant)

Relay bobbins, connector terminal bases, coil bobbins, new energy high-voltage components, electronic control housings, reflow soldering high-temperature resistant electronic bases.

3. General Industrial Applications (Wear-resistant, Corrosion-resistant, and Heat-resistant)
Water pump housings, fluid valves, transmission gears, sliding bearings, high-temperature pump and valve accessories, and various heat-resistant precision structural parts.

III. Product Advantages (Highlights of Lisu's Production Process)

1. Uniform glass fiber dispersion, no floating fibers, resulting in a smooth product surface;

2. Stable formula, minimal batch-to-batch color difference and property fluctuations, suitable for mass injection molding;

3. Available in black and natural-colored standard granules, with support for customized modification and adjustment;

4. Compatible with general injection molding processes in the automotive, electronics, and industrial sectors, ensuring strong consistency in finished product strength and heat resistance.
