FAQ
Q1: Can your EPDM compounds be colored?
A: Absolutely. While black is standard due to carbon black reinforcement, we offer a full spectrum of non-black colors using stable, heat-resistant pigments suitable for extrusion processes.
Q2: Are these compounds suitable for potable water applications?
A: Yes, we offer specific grades formulated to meet NSF/ANSI 61 or other relevant potable water standards, using approved ingredients to ensure safety and compliance.
Q3: What is the typical lead time for custom compound development?
A: Lead time varies based on complexity. Initial sample development typically takes 4-8 weeks, followed by pilot trials and final qualification to ensure the compound performs perfectly in your specific extrusion tubing application.
Q4: How do you ensure batch-to-batch consistency?
A: Consistency is critical. We employ statistical process control (SPC) throughout our manufacturing, from raw material inspection to final compound testing. Each batch is certified against a master batch to guarantee uniform properties.
Q5: Do you offer compounds with improved sustainability?
A: Yes. We are actively developing compounds with recycled content, bio-based plasticizers, and formulations designed for easier recycling, helping our customers meet their environmental goals without compromising performance.
