PTFE alternatives are advancing, with MedTech companies developing credible, application-specific solutions. See what’s setting the bar for alternatives and why replacing PTFE is more complex than a simple material swap for catheter liners, ePTFE applications, coatings, and sheaths.

How do you narrow product feature options without testing every possible combination? Join Applied Plastics for a live webinar exploring DOE through a real-world coating development example, and receive a…

In catheter development and manufacturing, inconsistent heat shrink removal can increase operator dependence, scrap, rework, and risk to delicate assemblies. In this sponsored technical blog post, Junkosha explains how FEP based peelable heat shrink tubing, engineered for controlled linear peelability, helps R&D and manufacturing teams support more repeatable bonding, forming, and lamination processes from development through scaled production.

Polymer selection shapes far more than a medical device’s baseline specs. In this episode, Saint-Gobain breaks down how stiffness, toughness, bonding, temperature, chemical exposure, and sterilization all influence catheter and…

Lubrizol is now on Chamfr with medical-grade silicone tubing, sheeting, and films for MedTech R&D teams. Source small quantities, compare standard sizes, and reduce friction for early testing, prototyping, design verification preparation, and supplier down-selection.

Heat shrink behavior can affect final device performance and assembly. In this sponsored technical blog post and full guide, Cobalt Polymers shares key considerations and use cases for selecting a material, shrink ratio, and wall thickness, including where Pebax® and Polyolefin Heat Shrink Tubing fit in medical device design.

PTFE remains a foundational catheter liner material, but material selection is becoming more complex. Explore why MedTech R&D teams are evaluating PTFE through a broader lens across performance, supply chain resilience, sterilization, and regulatory planning.

In this Chamfr Unboxed video, explore Cobalt Polymers’ Pebax® and Polyolefin Heat Shrink Tubing R&D kits in 2:1 and 4:1 shrink ratios. Quickly compare sizes, durometers, recovered dimensions, wall thicknesses,…

In this technical webinar, Cobalt Polymers experts discuss material behavior, use cases, and design considerations when using flexible, thin-walled heat shrink tubing. Watch the recording to leverage these insights, including…

Variability in PTFE coating thickness can introduce fit issues, dimensional inconsistency, and performance variation across catheter builds. In this sponsored technical blog post, Applied Plastics explores how process control in coatings supports tighter tolerances, more consistent assembly, and reliable outcomes across catheter development.

Alta Biomed’s PZF coating is gaining traction in blood-contacting devices. Learn how it balances performance, manufacturability, and testing to move from feasibility to scale.

Zeus is now on Chamfr, giving MedTech R&D teams access to ready-to-ship PTFE liners, FEP heat shrink, and FluoroPEELZ™ peelable heat shrink that enable design flexibility, more consistent builds, and faster iteration. Compare liner constructions, evaluate bonding approaches, and standardize assembly earlier in development.
