Need flame retardancy for transparent PC parts? This is the one! Xresin PC transparent FR masterbatch: halogen-free · non-dripping · high transparency · approx. 5% dosage achieves UL 94 V0 at 2.5 mm, successfully resolving the trade-off between flame retardancy and transparency.
PC (polycarbonate) offers high transparency and impact resistance and is widely used in lamp covers, appliance windows and housings. However, many flame-retardant solutions cost PC its transparency, cause yellowing or haze, or require halogenated flame retardants.
Xresin PC transparent FR masterbatch is a halogen-free formulation: at approx. 5%, it enables 2.5 mm transparent PC parts to achieve UL 94 V0 with no dripping when burning, while maintaining high transparency, a clean base color and batch consistency. It helps customers produce FR parts in-house from general-purpose transparent PC and cut costs significantly.

PC Transparent FR · Halogen-Free
Halogen-free · non-dripping · high transparency · V0 at 5% dosage
Add to transparent PC at approx. 5% to achieve UL 94 V0 at 2.5 mm while keeping transparency and a clean base color.
Material Features
- Halogen-free:Contains no halogenated flame retardants
- No dripping:No flaming drips when burning
- High transparency:Preserves the transparency of PC parts
- Clean base color:Solves base-color problems caused by FR masterbatches
- Approx. 5% dosage:Low dosage with minimal impact on PC's inherent properties
- 2.5 mm V0:Achieves V0 per UL 94 (depending on test standard)
- Stable and reliable:Consistent batch-to-batch performance
- Lower cost:General-purpose transparent PC + masterbatch instead of buying FR PC

Compared with Conventional PC FR Solutions
| Item | Xresin transparent FR masterbatch | Conventional FR solutions |
|---|---|---|
| Transparency | Maintains high transparency | Prone to haze and opacity |
| Base color | Clean | Prone to yellowing and graying |
| Halogens | Halogen-free | Some use halogenated flame retardants |
| Dripping | Non-dripping | Some solutions drip |
| Usage | Add approx. 5% masterbatch directly | Requires buying fully compounded FR resin |
| Cost | General-purpose PC + masterbatch, lower cost | FR compounds are relatively expensive |
Why Choose It for Transparent FR PC?
- Flame retardancy and transparency:Transparent PC parts no longer have to choose between flame retardancy and transparency.
- Halogen-free and more eco-friendly:Suitable for electronic and electrical products with halogen requirements.
- Low dosage:Only approx. 5% is needed, better preserving PC's original transparency and toughness.
- Flexible production:Use the same transparent PC resin for FR parts with masterbatch and standard parts without it, reducing inventory SKUs.

Main Applications
- LED lamp covers, transparent lighting components
- Transparent appliance windows, indicator covers
- Transparent electrical housings, charger housings
- Transparent FR PC parts with walls around 2.5 mm
FAQ
Is this masterbatch halogen-free?
Yes. The PC transparent FR masterbatch (2.5 mm grade) is halogen-free and does not drip when burning.
How much is needed to achieve V0?
At approx. 5%, 2.5 mm parts can achieve UL 94 V0. Results may vary under different test standards; samples are available for verification against your standard.
Will parts stay transparent with the masterbatch?
Yes, high transparency is maintained, and the yellow or gray base color caused by conventional FR masterbatches is reduced.
What should I choose for parts thinner than 2.5 mm?
For transparent parts with walls as thin as 0.8 mm, choose the PC Transparent FR Masterbatch (0.8 mm V0).
