Exploring Cost-Effective Flame Retardant PET Film Options for OEMs

Original Equipment Manufacturers (OEMs) across industries—from consumer electronics to electric vehicles—are constantly searching for ways to reduce production costs without compromising safety. When it comes to thermal and electrical insulation, selecting a cost effective flame retardant PET film is one of the most important yet challenging decisions.

In this article, we explore different flame retardant PET film solutions available on the market, including alternatives to expensive UL94 VTM-0-rated films, and how OEMs can smartly balance protection and budget.

Why OEMs Need Flame Retardant PET Film

OEMs operate in sectors that must adhere to strict fire safety regulations and certifications, such as:

• UL94 (VTM-0, V-1, HB)
• IEC 60695
• RoHS and REACH compliance

Whether you're producing wearable medical sensors or EV battery modules, insulation materials like PET films are crucial for ensuring flame retardancy, electrical insulation, and structural stability.

However, the gold-standard VTM-0 PET film is often priced out of reach for many projects, prompting engineers to seek an alternative to VTM-0 PET film that still meets performance goals.

Key Criteria When Selecting Alternatives

When considering alternatives to high-grade PET films, OEMs should evaluate the following:

• UL rating: VTM-1 and V-1 may be acceptable for non-critical areas.
• Additive type: Halogen-free flame retardants are ideal for eco-compliance.
• Surface treatment: Coated PET films can offer fire resistance at lower cost.
• Thickness and mechanical performance: Thinner films reduce material use.

Working with a vendor that specializes in flame retardant PET film solutions allows OEMs to find a solution tailored to specific use cases.

Modular Flame Retardant Strategy for OEMs

Rather than using a single high-cost film throughout a device, many OEMs are implementing a modular insulation consulting approach:

• Zone A (high heat zones): use VTM-0 PET film
• Zone B (low-risk areas): switch to VTM-1 or coated PET film
• Zone C (non-electrical): use standard insulation PET

This approach, combined with die-cut PET film services, significantly reduces material waste and ensures strategic deployment of premium films.

Case Study: Consumer Electronics Brand

A well-known brand producing IoT home devices reduced flame retardant film expenses by:

• Switching from full-body VTM-0 PET film to a budget flame retardant solution
• Using custom PET film rolls to avoid trimming losses
• Employing UL testing support to validate film substitution

The result: 37% cost savings per unit and continued compliance with UL94 V-1 standards.

How to Engage the Right Supplier

OEMs looking to source reliable and cost effective flame retardant PET film should seek vendors that offer:

• Low MOQs (minimum order quantities)
• In-house testing and certification documentation
• Access to a material compatibility database
• Guidance on alternative to VTM-0 PET film usage

Such partnerships allow OEMs to maintain both product integrity and competitive pricing.

Final Thoughts

Flame retardant PET film is a vital component of modern electronics and electrical equipment. But “safe” doesn’t always have to mean “expensive.” With the right flame retardant PET film solutions, especially designed for OEM workflows, manufacturers can keep costs under control while meeting required safety certifications.
