Description
This premium 25% glass filled acetal C rod is a high-performance engineering plastic designed for demanding structural and precision applications. Reinforced with glass fibre, it offers significantly increased stiffness, strength and dimensional stability compared with standard acetal, making it ideal for machined components that must retain tight tolerances under load.
Combining excellent thermal stability with very low water absorption, this material maintains its mechanical properties in challenging environments where moisture, temperature variation and continuous stress are present. Supplied as solid round rod in a choice of diameters and lengths, it is well suited to CNC machining, turning and milling for use in mechanical, automotive, food-processing and general industrial equipment.
Product Features
- Manufactured from acetal reinforced with 25% glass fibre for enhanced rigidity and strength.
- Available diameters: 30 mm, 40 mm, 50 mm, 60 mm and 80 mm to suit a wide range of component sizes.
- Supplied in standard lengths of 1000 mm, 2000 mm and 3000 mm for flexible cutting and machining.
- High thermal stability, maintaining performance over a broad service temperature range.
- Very low water absorption for excellent dimensional stability in humid or wet environments.
- Good wear resistance and fatigue strength for dynamic and load-bearing applications.
- Machinable using conventional metalworking and plastics-processing equipment.
Key Features and Benefits
- High load capacity: 25% glass filling significantly increases stiffness and tensile strength, enabling thinner, lighter components to carry higher loads.
- Dimensional stability: minimal moisture uptake and low creep help components hold tight machined tolerances over time.
- Thermal performance: stable mechanical properties across varying temperatures reduce risk of deformation or failure in heated machinery.
- Extended service life: excellent wear and fatigue resistance support long-term use in moving parts and repetitive motion assemblies.
- Consistent machinability: rods can be turned, milled and drilled to fine finishes, helping reduce secondary finishing operations.
- Material optimisation: wide choice of diameters and lengths helps minimise waste and optimise stock for production runs or one-off parts.

Frequently Asked Questions
How does 25% glass filled acetal compare to standard acetal rod?
The 25% glass filled grade offers significantly higher stiffness, tensile strength and dimensional stability than standard unfilled acetal. This makes it better suited to heavily loaded or structural components, although it can be slightly more abrasive to cutting tools and may have a less glossy machined surface.
Can these rods be machined using standard metalworking equipment?
Yes, the rods can be machined with conventional metalworking tools such as lathes, mills and drills. Sharp tools, appropriate cutting speeds and adequate support are recommended to achieve accurate tolerances and clean finishes, and tool wear may be higher than with unfilled plastics due to the glass reinforcement.
Is 25% glass filled acetal suitable for use in wet or humid environments?
Yes, one of the key advantages of acetal is its very low water absorption, and the glass-filled grade maintains this characteristic. This results in excellent dimensional stability and consistent performance in humid, damp or intermittently wet conditions, provided the overall chemical and temperature environment is compatible with the material.
