White PPS Granules A504X90 Glass Fiber Reinforced High Temperature Resistant Material

White PPS Granules A504X90 Glass Fiber Reinforced High Temperature Resistant Material

White PPS (polyphenylene sulfide) particles, especially PPS+GF40 (i.e. polyphenylene sulfide containing 40% glass fiber reinforced), is a high-performance engineering plastic that is widely used because of its unique physical and chemical properties. in multiple fields.

Here’s a detailed breakdown of this material:
1. Material properties
High temperature resistance: PPS material itself has high thermal stability, and the continuous use temperature can reach 200~240℃, while glass fiber reinforced PPS+GF40 has higher thermal performance indicators, and some brands of products can even Continuous use at higher temperatures.
High strength and rigidity: The addition of glass fiber significantly improves the strength and rigidity of PPS, enabling it to meet higher mechanical performance requirements.
Flame retardancy: PPS material itself has certain flame retardancy, while PPS+GF40 can usually achieve higher flame retardancy levels, such as UL94 V-0, etc.
Chemical corrosion resistance: PPS+GF40 has good corrosion resistance to a variety of chemical substances and can remain stable in harsh chemical environments.
Dimensional stability: This material has excellent dimensional stability during processing and use, and can meet the requirements of precision manufacturing.
2. Application fields
Automotive industry: PPS+GF40 is widely used in engine peripheral components, exhaust system components, electrical system components, etc. in the automotive industry, such as igniters, heaters, thermostats, lamp holders, bearings, etc. Due to its high temperature resistance, high strength and flame retardant properties, PPS+GF40 can replace metal to make certain parts, thereby reducing vehicle weight and improving fuel efficiency.
Electronic and electrical appliances: This material is mainly used in the field of electronic and electrical appliances to manufacture components that require high temperature resistance, flame retardancy and impact resistance, such as switches, sockets, connectors, relay shells, etc.
Machinery industry: PPS+GF40 is used in the machinery industry to manufacture shells, structural parts, wear-resistant parts and sealing materials, such as pump bodies, valves, bearing brackets, piston rings and gears, etc.
Textile fibers: PPS+GF40 will also be used for certain textile fibers for specific purposes, such as in special industrial dust removal equipment.

3. Precautions
Processing temperature: The processing temperature of PPS+GF40 is relatively high, and the heating and cooling processes need to be controlled to avoid overheating, decomposition or scorching of the material.
Mold design: Since PPS+GF40 has a high melt viscosity, the mold design needs to take this into consideration to ensure good mold filling effect and product quality.
Storage conditions: The material should be stored in a dry, cool, well-ventilated environment, away from direct sunlight and high temperatures.
