Applications of Evonik VESTAMID® LC-GF23 NC Nylon 12, 23% Glass Fiber Reinforced in Industrial Manufacturing

As the direct manufacturer of reinforced nylon raw materials, we supply high-performance compounds for advanced engineering scenarios where chemical, mechanical, and thermal stability are critical. Below we present main industrial downstream applications for our 23% glass fiber reinforced Nylon 12 grade, each with specific technical practices and market standards.

1. Automotive Fuel and Brake Line Connectors

Automotive Tier 1 and OEM component shops select this material for pressure-resistant connectors in fuel, brake, and UREA systems. The glass fiber reinforcement delivers the dimensional accuracy, chemical resistance, and hydrolysis stability necessary for fluid management parts exposed to aggressive media and continuous vibration. Processing lines often use this raw compound via precision injection molding, with temperature-controlled barrel settings and short residence times to minimize material degradation. Post-mold aging or annealing may follow to stabilize final dimensions. End customers require tight burst-pressure, permeability, and repeated cycling tolerance for these critical safety components.
