In industries where corrosion resistance, chemical compatibility, and long service life are non-negotiable, Kynar®—also known as PVDF (polyvinylidene fluoride)—has become one of the most trusted thermoplastic materials available. From chemical plants to water treatment facilities, PVDF plays a critical role in keeping systems safe, reliable, and efficient.

At Custom Fiberglass Products Inc., we regularly work with Kynar/PVDF in demanding environments where other materials simply don’t hold up. Here’s a closer look at what makes this material so valuable and when it’s the right choice for your application.

---

What Is Kynar® (PVDF)?

Kynar® is Arkema’s trade name for PVDF, a high-performance fluoropolymer known for its exceptional resistance to chemicals, heat, and UV exposure. Unlike many plastics, PVDF maintains its mechanical strength and chemical stability over long periods of time—even in harsh industrial environments.

Because of these properties, Kynar/PVDF is widely used in:

• Chemical processing plants
• Semiconductor manufacturing
• Water and wastewater treatment
• Industrial exhaust and scrubber systems
• Corrosive fluid handling applications

---

Key Benefits of Kynar® (PVDF)

1. Outstanding Chemical Resistance

PVDF is resistant to a wide range of aggressive chemicals, including:

• Acids and bases
• Halogens
• Oxidizers
• Chlorinated compounds

This makes it an excellent choice for applications where corrosion is a constant concern.

2. High Temperature Performance

Kynar/PVDF performs reliably at elevated temperatures, typically up to 300°F (150°C) depending on the application. It maintains strength and dimensional stability better than many other thermoplastics.

3. UV and Weather Resistance

Unlike many plastics that degrade in outdoor environments, PVDF has excellent UV resistance, making it suitable for outdoor piping, ducting, and equipment exposed to sunlight.

4. Long Service Life

When properly designed and installed, PVDF systems can provide decades of service, reducing downtime, maintenance costs, and replacement frequency.

5. Clean and Pure Material

PVDF has very low extractables, which makes it ideal for high-purity applications where contamination must be minimized.

---

2. Star Wars: The Force Awakens & The Mandalorian

Lucasfilm’s prop department used 3D printing extensively to create blasters, lightsaber hilts, and even parts of droid characters. This wasn’t just for looks—the props needed to be functional for stunt work and survive multiple takes.

BB-8? Many of his on-screen versions have 3D printed shells and components for quick swapping between hero shots and stunt rigs.

---

3. Jurassic World Dinosaurs

The dinosaurs were mostly CGI, but the animatronic heads, claws, and smaller creatures were often 3D printed for close-up shots where actors interact physically with them.

This kept performances more natural while saving money compared to sculpting every detail by hand.

---

4. Stop-Motion Magic

Studios like Laika (Coraline, Kubo and the Two Strings) use 3D printing to create thousands of interchangeable facial expressions for their characters. This lets animators swap faces quickly while keeping expressions perfectly consistent.

---

5. The Batman (2022)

Introduction: What is PVC?

Polyvinyl Chloride (PVC) is a thermoplastic polymer made from the polymerization of vinyl chloride monomers. Discovered in the 19th century and commercially produced since the early 20th, PVC is now one of the most versatile and widely used plastics in the world—second only to polyethylene in global production volume.

PVC is favored for its durability, affordability, chemical resistance, and adaptability. It can be made rigid or flexible, clear or colored, and engineered for indoor or outdoor applications.

---

Chemical Composition & Structure

PVC’s backbone is built from repeating vinyl chloride monomer units (CH₂=CHCl). The chlorine atoms bonded to the carbon chain give PVC its fire-retardant properties and chemical resistance—making it stand out among commodity plastics.

Types of PVC

PVC is typically classified into two main types, each with unique uses:

1. Rigid PVC (uPVC or Unplasticized PVC)

• Hard and stiff
• Used in pipes, window frames, siding, panels, and enclosures
• Resistant to UV, moisture, and most chemicals

2. Flexible PVC (Plasticized PVC)

• Modified with plasticizers (commonly phthalates) to enhance flexibility
• Used in wire insulation, inflatable products, flexible tubing, and flooring
• Softer and more elastic than rigid PVC

---

Key Properties of PVC

• Density: ~1.38 g/cm³ (denser than most thermoplastics)
• Tensile Strength: 34–62 MPa (depending on formulation)
• Thermal Resistance: Softens at ~80–85°C
