V. Technical Q&A
❓ Q: What does "64% biobased carbon content" mean, and why is it important?
→ According to DIN EN 16640, this means 64% of the product’s carbon comes from renewable biomass sources rather than fossil resources. This significantly reduces the product’s carbon footprint, representing a concrete step toward a circular economy.
❓ Q: Any recommendations for choosing among the seven colors?
→ The variety of colors greatly facilitates on-site color coding and management. For example, different colors can distinguish electrical phases, pipeline contents, safety zones, or product categories. The blue version with a release liner also supports die-cutting applications.
❓ Q: How does the tape perform in high-temperature environments?
→ The product can withstand temperatures up to 140°C for 30 minutes, making it suitable for most industrial environments, including areas near processes requiring short-term heat resistance.
