Selection Guide for PTFE High-Temperature Tape for Demolding & Anti-Stick Applications of Injection Molding Machines
This guide covers PTFE high-temperature tape selection for injection molding demolding and anti-stick applications. Temperature-based selection: ≤260°C for general plastics (standard silicone PSA tape, 0.13-0.18mm); 260-300°C for high-temperature engineering plastics like PC, PA66, POM (high-temp silicone adhesive, 0.18-0.25mm); 300-400°C for PEEK, LCP, PPS near hot runners (adhesive tape fails; use adhesive-free PTFE cloth or PFA film). Material-based selection: tacky materials need high-release pure PTFE surfaces; glass/mineral filled materials require heavy-duty 0.25mm+ wear-resistant tape; corrosive additives demand chemically resistant adhesive and dense substrate; static-sensitive applications need anti-static black PTFE tape.
