Product Description

KANZAKI®FR801 is an environmentally friendly, high-efficiency flame retardant developed by the KANZAKI brand for PVC, rubber, and engineering plastic flame-retardant systems.

It offers good flame-retardant efficiency, low-smoke performance, and processing stability. It helps materials form a more stable flame-retardant protection system during combustion, improving self-extinguishing performance, smoke suppression, and overall fire safety.

KANZAKI®FR801 is suitable for industrial formulation systems with high requirements for environmental compliance, flame-retardant stability, and processing adaptability. It is especially suitable for continuous production applications such as wires and cables, building materials, plastic profiles, and rubber products.

Applications

◆ Flame-retardant PVC cable compounds
◆ PVC conduits, profiles, and sheets
◆ PVC flooring, wall panels, and architectural decorative materials
◆ Flame-retardant rubber products
◆ Wire and cable sheathing and insulation materials
◆ Building and infrastructure flame-retardant materials
◆ Other plastic products requiring low-smoke and stable flame-retardant performance

Flame Retardant Mechanism

During the initial stage of combustion, KANZAKI®FR801 can promote the formation of a dense and stable char protective layer on the material surface, reducing oxygen penetration into the material and lowering the release rate of combustible gases.

At the same time, under high-temperature conditions, KANZAKI®FR801 works synergistically with the flame-retardant system to reduce the heat release intensity in the combustion zone and suppress continuous flame spread.

During heating and combustion, KANZAKI®FR801 helps improve char formation, reduce dripping risk, and enhance the stability of the flame-retardant system, thereby helping finished products achieve better self-extinguishing performance after flame removal.

Recommended Dosage

PVC Systems:

◆ Recommended dosage: 8–15 phr
◆ Can be adjusted according to flame-retardant rating, product thickness, and formulation system
◆ For higher flame-retardant requirements, it can be used together with flame retardant synergist KANZAKI®FS430

Rubber Systems:

◆ Recommended dosage: 10–20 phr
◆ Suitable for flame-retardant rubber sheathing, sealing parts, soft flame-retardant products, etc.
◆ Formulation optimization should be carried out according to rubber type, filler system, and testing standards

Engineering Plastic Systems:

◆ Recommended dosage: 10–18 phr
◆ Small-scale trials are recommended first to evaluate dispersibility, mechanical properties, and flame-retardant rating performance

Important Notes

1. KANZAKI®FR801 is a high-efficiency environmentally friendly flame retardant. Please use it rationally according to actual application requirements.

2. Different resin systems, filler ratios, product thicknesses, and processing conditions may affect the final flame-retardant performance.

3. Small-scale and pilot trials are recommended before use to confirm flame-retardant rating, processing stability, and finished product performance.

4. Seal the package properly after use to prevent moisture absorption.

5. It is recommended to test KANZAKI®FR801 together with KANZAKI flame retardant synergist KANZAKI®FS430 to obtain a more efficient and stable flame-retardant system.
