PVC materials are widely used in critical applications within the semiconductor and related industries. PVC’s broad use ranges from process tools that manufacture IC chips to FM 4910 compliant sheets used in cleanrooms and wet benches.

It’s also extensively used in pipes and fluid fixtures throughout fabs. PVC plays a major role in semiconductor device production, making it important to understand its properties and applications.

What is PVC?

Polyvinyl Chloride (PVC) is the third most-produced polymer resin worldwide, with nearly 40 million pounds used annually. It is a flexible or rigid material that’s easily machined, heat-formed, and welded—making it ideal for semiconductor applications.

There are three primary types of PVC used:

• Type I: Excellent corrosion resistance, lower impact strength – widely used in process tools.
• Type II: Higher impact strength, reduced chemical resistance – less common in chip fabs.
• CPVC (Chlorinated PVC): Enhanced temperature resistance, more robust against degradation.

PVC Type I vs. Type II

Type I PVC offers normal impact strength and outstanding corrosion resistance, making it the most common choice in semiconductor applications. Type II is used where higher impact resistance is needed, though it compromises on chemical resistance.

CPVC vs. PVC

CPVC replaces more hydrogen atoms with chlorine, enhancing the resin's thermal stability. CPVC can endure temperatures up to 200°F compared to PVC’s limit of 140°F, making it suitable for more demanding environments.

Why PVC Matters in Semiconductor Manufacturing

PVC-based materials bring significant value to the semiconductor industry by offering tailored compounds in a wide variety of formats—clear materials for visibility and FM 4910 compliant versions for flame retardance in cleanroom environments.
