People Also Ask:
What is PPS GF50?
It's an ultra-stiff, high-performance composite with a PPS matrix and 50% glass fiber, designed for structural auto parts and industrial pump parts that require metal-like rigidity and chemical resistance.
What is the stiffness of PPS GF50?
With a tensile modulus often exceeding 17,000 MPa, LFT-G PPS GF50 is one of the stiffest injection-moldable thermoplastics available, approaching the rigidity of some aluminum alloys while being significantly lighter.
Is PPS suitable for precision components?
Absolutely. Due to its extremely low moisture absorption, low coefficient of thermal expansion (CLTE), and high stiffness, PPS maintains its shape and tolerances exceptionally well, making it ideal for precision parts in demanding environments.

Case Study: Precision Sensor Housing
The Challenge
A manufacturer of high-precision scientific instruments required a housing for a new laser measurement sensor. The housing had to maintain absolute dimensional stability across a wide operating temperature range (-40°C to 150°C) to ensure the laser's alignment was never compromised. The material also needed to be immune to various cleaning solvents. The initial design using a machined aluminum block was accurate but prohibitively expensive and heavy for a portable device.
The Solution: LFT-G-PPS-LGF50-NG05
Our ultra-stiff PPS composite was the perfect fit. Its extremely high modulus (17,000 MPa) and very low Coefficient of Linear Thermal Expansion (CLTE) ensured the housing remained dimensionally stable, protecting the sensitive optics. The material's near-zero moisture absorption and broad chemical resistance meant performance was consistent regardless of humidity or exposure to solvents. We were able to injection mold the part with all its complex internal features in a single step, eliminating all machining.
Result: A 65% lighter sensor housing that maintained sub-micron alignment accuracy across all tests, with a 70% reduction in total part cost.
