CF40 PPS Engineering Plastic
What kind of product is LCF40 PPS?
LCF40 PPS is a high-performance engineering plastic made from PPS (polyphenylene sulfide) as the base material and reinforced by 40% long carbon fibers through a 40% long carbon fiber reinforcement technology. It is specifically designed for high-strength, high-temperature service and complex structure injection-molded parts.
This material not only maintains the original heat resistance, chemical resistance, and dimensional stability of PPS but also significantly enhances the structural load-bearing capacity, rigidity level, and long-term usability reliability. It can meet the extremely high requirements for material performance and structural integration in various applications.
Why does the LCF40 PPS have high performance?
The performance advantages of LCF40 PPS do not stem from parameter stacking, but rather from the design logic of the internal structure of the material.
The PPS matrix provides a stable foundation.
Long carbon fibers determine the structural performance
The PPS itself has the following characteristics:
Long-term resistance to high temperatures
Extremely low water absorption rate, maintaining dimensional stability
Excellent resistance to chemical corrosion
Good electrical and thermal stability properties
Unlike short fiber reinforcements, long carbon fibers can retain a more continuous fiber length in the product, forming a stable force transmission path:
Strength and rigidity are significantly enhanced
The load-bearing capacity is closer to that of structural materials
The fatigue resistance and impact resistance are more reliable
The performance is more balanced in complex structures
This ensures that the material will not easily "fail" under complex conditions.
This is the fundamental reason why the LCF40 PPS can be competent for bearing-type and functional-type integrated structural components.
What problems can LCF40 PPS solve? | Regarding the pain points of the product
In the actual product development process, structural components often encounter several "conflicting requirements" simultaneously:
Desire for higher strength and rigidity
Wish for the material to be lightweight to achieve lightweighting
Need for long-term stable operation in high-temperature environments
The component structure is complex and can only be produced through injection molding
Do not want to introduce excessively high manufacturing and assembly costs
Short-fiber PPS: Has sufficient heat resistance but is limited in strength and rigidity.
Metal materials: They have sufficient strength, but they are heavy, have limited structure, and have a high cost.
The value of LCF40 PPS compound resin lies in the fact that it can raise the structural performance to a new level without altering the injection molding process path. This enables us to effectively solve various problems we encounter. What it addresses is not merely a single performance issue, but rather a combination of real-world issues such as "insufficient performance + structural limitations".
How can LCF40 PPS be used by customers?
LCF40 PPS composite is suitable for product development scenarios where one desires to achieve lightweight design, structural simplification, and stable mass production without sacrificing performance.
In practical applications, LCF40 PPS is commonly used in various industry products. These components share some common characteristics, namely they cannot deform, cannot fail, and cannot be easily replaced. The LCF40 PPS is precisely designed for such high-demand structural components.
Structural support components working in high-temperature environments
Injection-molded structural components with both bearing and fixation functions
High-stiffness shell and functional shell
Assembly components with high requirements for dimensional stability
Originally using metal but hoping to achieve lightweighting for the structural components
Motor End Cap
Original problem: The short fiber PPS end cover lacks rigidity under high-temperature operation and long-term vibration conditions, posing a risk of micro-deformation, which affects coaxiality and assembly stability.
Selection reason: LCF40 PPS maintains higher structural rigidity and dimensional stability at high temperatures and can withstand continuous mechanical loads.
Performance: The end cover structure is stable, the assembly accuracy is improved, and the long-term operational reliability is enhanced.
Mounting Base
Original concern: The metal base is heavy, and the processing and assembly costs are high.
Selection reason: LCF40 PPS plastic pellet meets the requirements for structural strength while achieving lightweighting and integrated molding.
Usage effect: The system weight has decreased, and the manufacturing and assembly costs have also been reduced.
Frequently Asked Questions
What are the differences between LCF40 PPS and ordinary SCF PPS?
+
-
LCF40 PPS is reinforced with long carbon fibers, which retain longer fibers. Its structural load-bearing capacity and rigidity are significantly higher than those of short-fiber PPS, making it more suitable for structural component applications.
Is LCF40 PPS suitable for long-term use in high-temperature environments?
+
-
Suitable. The PPS matrix has excellent high-temperature resistance, and when combined with long carbon fibers, it can maintain structural stability under high-temperature conditions.
Can LCF40 PPS material be used for load-bearing injection-molded structural components?
+
-
Yes. The strength and rigidity of LCF40 PPS are significantly superior to those of conventional reinforced plastics, making it suitable for use in integrated injection-molded parts that perform both structural and fixation functions.
Can LCF40 PPS material replace metal components?
+
-
It can be used in some structural applications. It achieves lightweight and structural integration while meeting the structural strength requirements, but the specific implementation needs to be evaluated based on the actual load conditions.
