Ertacetal C is an unfilled acetal copolymer (POM-C) engineered for consistent mechanical performance across a wide service temperature range. It provides a tensile strength of 66 MPa, a low coefficient of friction (0.3) and dependable dimensional stability, making it a practical choice for precision components.
With a continuous-use temperature span from -50 °C to 100 °C and medium chemical resistance, Ertacetal C suits applications where both thermal resilience and moderate chemical exposure are expected. Its low moisture uptake helps maintain tight tolerances in humid or wet environments, while the material's inherent machinability allows rapid prototyping and production on standard metalworking equipment.
Dotmar stocks Ertacetal C in rod and sheet formats and can supply cut-to-size pieces or fully machined parts. Australian customers benefit from local inventory, technical support and prompt delivery, ensuring project timelines are met without compromise on material quality.
