LFT-G® LGF30 PPS Plastic
What is LGF30 PPS Engineering Plastic?
LGF30 PPS is a high-performance engineering composite material that is based on polyphenylene sulfide (PPS) resin and is reinforced by adding 30% long glass fibers (approximately 5–25mm continuous long fiber structure).
LGF30 PPS Performance Overview
Mechanical properties
High tensile strength (significantly higher than SGF PPS)
High bending modulus, strong anti-deformation ability
Excellent impact toughness (long fibers can effectively absorb energy)
Extremely low creep deformation, stable under long-term load
Thermal Properties
The long-term operating temperature can reach above 200°C, with a high heat distortion temperature.
Dimensional Stability
Extremely low thermal expansion coefficient (close to that of metals), with minimal dimensional changes in high temperature and humid environments.
Chemical and Environmental Performance
Resistant to acids and alkalis, salt spray, oils and fuels
Excellent hydrolysis resistance
Strong anti-aging ability
Electrical Performance
Excellent insulation properties, stable electrical performance even under high temperatures.

Why choose LGF30 PPS?
The main reason for choosing this material is not "replacing plastic", but:
-
Address the issue of overheating failure
Ordinary engineering plastics exhibit rapid performance degradation above 180°C, while the PPS system remains stable. -
Solves the problems of metal weight and corrosion
Achieve lightweight substitution while maintaining the strength. -
Resolve the issue of dimensional accuracy
Low water absorption + low thermal expansion → Long-term stable assembly. -
Solves the problem of long-term fatigue
The long glass fiber structure significantly enhances the cycle load life.
Everything You Need to Know
What temperature range can LGF30 PPS withstand?
LGF30 PPS is suitable for long-term use in high-temperature environments, typically above 200°C, while maintaining stable mechanical and dimensional performance under continuous thermal stress.
Why choose LGF30 PPS over other engineering plastics like PA66 or PBT?
LGF30 PPS is preferred when higher performance is required, especially in:
Higher temperature environments
More aggressive chemical conditions
Higher long-term mechanical load
Applications requiring superior dimensional stability and low creep
Compared to PA66 or PBT, PPS-based composites provide significantly better thermal and chemical resistance.
Can LGF30 PPS replace metal components?
Yes, in many applications LGF30 PPS can partially replace metal parts such as aluminum or die-cast components. It offers significant weight reduction, corrosion resistance, and design flexibility while maintaining strong structural performance.
The value of LGF30 PPS lies not only in the improvement of a single performance, but also in the enhancement of its "overall engineering capability":
Maintain structural stability under high-temperature conditions
Maintain low creep and high rigidity under long-term loading
Maintain long-term reliability in corrosive environments
Replace metal structural components in lightweight designs
