What Are The Fire-Rated Correx Sheets?
Fire-rated Correx sheets are also called fire rated coroplast, fire rated corrugated plastic sheets. It is a pp hollow board with a flame-retardant effect by adding flame retardant to polypropylene raw material through extrusion molding. Usually, flame-retardant coroplast sheet is divided into three grades: V2, V1, and V0. The flame-retardant correx can automatically extinguish after leaving the fire source and will not become a fire-inducing material.
The Fire-rated correx sheets can be made into various products, such as flame retardant floor protection at the welding operation site, flame-retardant coroplast boxes, corrugated plastic tree guards, layer pads, fruit & vegetable packaging boxes, recyclable PP Logistic Box, etc.
Customize Your Fire-Rated Correx Sheets
We have many kinds of fire-rated Correx sheets for customers. Some of the common types our customers use are as follows:
It is an ideal temporary protection product to use for floor protection, wall protection, furniture protection, etc.
It is suitable for storing flammable materials or for use in warehouses and workshops with fire safety requirements.
It is suitable for use in forest farms, municipal greening, and other scenarios that require fire prevention.
Fireproof layer pad, used for interlayer separation during transportation of bottled and canned products.
Key Features of Fire-Rated Correx Sheets

PP material is chemical-resistant, waterproof, and will not rust after long-term use.

Good toughness, resistant to collisions, can effectively protect goods from damage.

Much lighter than cardboard or foam partitions. Reduces packaging costs.

Unlike cardboard, our PP dividers will not weaken or deform when exposed to moisture.
Stable performance between differeeent batches
We have been in this industry for 13 years, and the formula for fire-rated Correx sheets is repeatedly tested and adjusted by us.
It’s not about buying ready-made flame-retardant master batch and mixing it randomly, but about blending different flame-retardant formulas according to different thicknesses, colors, and uses. So our fire-rated Correx sheets have stable performance between batches, and there will not be a situation where this batch can pass V0, and the next batch cannot pass.


We Control the Entire Process Ensure the Premium Quality
We have 16 fully automated production lines with an annual output of over 20000 tons of fire-rated Correx sheets. The production process parameters of fireproof board are developed by ourselves, from raw material to extrusion molding, the whole process is completed in our own factory, without outsourcing.
After each batch of boards is produced, we conduct our own flame retardant testing to ensure compliance with UL94 V-0 standards before packaging and shipping.

Testimonials
A2: Yes, our fire-rated sheets maintain their impact resistance, stiffness, and durability. The flame-retardant materials do not affect the sheet’s strength.
As long as the board is not damaged, the flame retardant performance will not disappear.
Our flame retardants are mixed in PP raw materials, not surface coatings. So as long as the board itself is not damaged by high temperature or strong acid and alkali, the flame retardant effect will always exist. It won’t expire after one year like spraying flame retardants.
How to choose the fire rating for fire rated Correx sheets?
The requirements for fire protection levels vary in different scenarios and industries. Many peolple don’t know how to choose the suitable fire rate. Today, I will explain the UL94 fire rating standards clearly and help you choose the right rating without wasting money.
What does fire rating really mean?
UL94 is currently the most widely used plastic fire rating standard internationally. It mainly measures three indicators:
How long does it take to extinguish after leaving the fire?
Is there any molten material dripping during combustion?
Will the dripping molten material continue to burn?
According to these three indicators, UL94 divides the fire rating of plastics into three levels: V2, V1, and V0, from low to high.
Explain the differences between the three levels in a table
| Grade | Test Method | Extinguishing Time | Dripping Allowed? | Combustible Drip? | Rating Level |
|---|---|---|---|---|---|
| V2 | Two 10-second burn tests | Extinguishes within 60s | Yes | Yes | Lowest |
| V1 | Two 10-second burn tests | Extinguishes within 60s | No | No | Medium |
| V0 | Two 10-second burn tests | Extinguishes within 30s | No | No | Highest |
What scenarios use V2?
- General storage with low fire protection requirements
- Short-term turnover packaging
- Cost-sensitive scenarios without mandatory fire safety requirements
Note: Although V2 boards can self-extinguish, dripping combustibles may ignite goods or the floor below.
Not recommended if flammable materials are present in the warehouse.
What scenarios use V1?
- Layer pads and partitions on warehouse shelves
- Scenarios with fire safety requirements, but not particularly strict
- Customers who need to balance cost and a certain level of security
Note: V1 prohibits dripping of burning molten material. This requirement is critical because many fires spread not due to burning of the board itself, but because the material drips onto cardboard boxes or wooden pallets below, buring other items.
What scenarios require the use of V0?
- Construction site: temporary enclosures, ground protection panels, strict fire safety inspections;
- Electronic factory: electronic component packaging must be both fire-resistant and anti-static;
- Aerospace: component packaging with extremely high fire resistance requirements;
- Public transportation: temporary partitions on subways, high-speed trains, and airplanes;
- Export to Europe and America: many countries have mandatory V0 requirements for packaging materials of imported products.
Remenber the simple principle
When unsure which level to choose, choose high instead of low.
V0 is not much more expensive than V2, but in case of a fire accident, the loss would be several hundred times the cost of the board. Moreover, many customers buy V2 for the first time, but later fail the fire safety inspection and switch back to V0, which actually incurs an additional shipping and labor cost.
Directly going to V0 is the most convenient.
The notice when buying fire rated Correx sheets
To test the report, don’t just listen to him say: the supplier says’ fire prevention ‘, you have to ask him to bring out the UL94 test report. The batch number on the report should correspond to the actual shipped board.
Batch stability: The flame retardant formula of the fireproof board is crucial, and the performance between different batches cannot fluctuate. Find a factory with its own production line and years of experience, ensuring batch consistency.
Other functions can be added: If you need both fire and static electricity prevention, or both fire and food-grade, find a supplier who can do formula stacking at once, without buying two types of boards to piece together. Purepack’ fire rated Correx sheets may be a good choice.
Summary
Choosing the right level meets safety requirements without wasting money. Choosing the wrong option, either failing the acceptance or incurring additional costs, is not cost-effective.
Please send us your usage scenario and fire prevention requirements, and we will recommend the most suitable grade and thickness for you.
