30% Long Glass Fiber Reinforced PPS (LFT-PPS-LGF30-NG03)
This is our premier solution for the most hostile chemical and thermal environments. LFT-PPS-LGF30-NG03 combines the exceptional dimensional stability and strength of a 30% long glass fiber structure with the inherent chemical immunity and high-heat dominance of a Polyphenylene Sulfide (PPS) matrix. It is engineered to perform where other high-performance plastics fail. In short, this page details an engineering solution for extreme environments (LFT-PPS-LGF30-NG03) - blending the strength of 30% long fiber with the superior chemical and thermal resistance of PPS for the most demanding automotive fluid systems and industrial pump parts.
People Also Ask:
What is PPS GF30?
It is a high-performance composite made from a PPS matrix with 30% glass fiber. Our long-fiber version enhances this with superior toughness, making it ideal for structural auto parts and pump parts exposed to harsh chemicals.
What is PPS plastic resistant to?
PPS offers the broadest chemical resistance of any advanced engineering plastic. It is virtually immune to automotive fluids, fuels, strong acids, bases, and solvents, even at temperatures up to 200°C (400°F).
Is PPS better than PEEK?
While PEEK offers slightly higher temperature performance, PPS provides comparable chemical resistance and excellent mechanical properties at a significantly more cost-effective price point, making it the superior value choice for many high-end applications.

| Brake Fluid (Glycol) | Excellent |
| Sulfuric Acid (30%) | Excellent |
| Sodium Hydroxide (10%) | Excellent |
Strength Retention at High Temperature
LFT-PPS-LGF30 retains a high percentage of its strength even at 200°C, while polyamides (dashed line) see a significant drop-off.
Case Study: Industrial Chemical Pump Housing
The Challenge
A manufacturer of industrial pumps for the chemical processing industry needed to replace a stainless steel pump housing. While durable, the metal housing was extremely heavy, expensive to machine, and had long lead times. They required a thermoplastic that could withstand a continuous flow of aggressive solvents and acids at temperatures exceeding 150°C, without swelling, cracking, or degrading over a long service life.
The Solution: LFT-PPS-LGF30-NG03
Our PPS long-fiber composite was the only material that met the extreme chemical and thermal requirements. The PPS matrix provided near-universal chemical immunity, while the 30% long glass fiber core delivered the mechanical strength and creep resistance to handle high internal pressures. We provided extensive compatibility data and worked with their team to ensure the mold design accounted for the unique processing characteristics of PPS.
Result: A 70% lighter pump housing that passed all chemical immersion and pressure cycle tests, with a 40% reduction in production cost and a 60% faster manufacturing time.
