FR5365 FR5368 Halogen-Free Flame Retardant PC ABS - Electronic Enclosures

The shift toward halogen-free flame retardant systems in electronics and automotive applications is no longer a trend—it is a regulatory and market reality. Over the past decade, we have seen OEMs across Asia, Europe, and North America progressively phase out halogenated flame retardants in favor of phosphorus- and nitrogen-based systems that offer lower smoke emission and reduced toxicity during combustion. Yet many engineering teams face a persistent challenge: finding a halogen-free PC/ABS alloy that delivers consistent V-0 performance, good flow for thin-wall molding, and heat resistance adequate for real-world operating conditions—all at a cost structure that makes commercial sense. FR5365 and FR5368 are two halogen-free flame retardant PC/ABS alloys developed by our own compounding facility, Primetech Plastics, to address exactly this gap.

What sets these grades apart is not just the data sheet—it is the combination of stable production, responsive technical support, and a supply chain that keeps material on the shelf when you need it.

Key Properties

Halogen-Free Flame Retardancy – UL94 V-0 at 1.6mm

Both grades achieve UL94 V-0 classification at 1.6mm thickness. The flame retardant system is chlorine- and bromine-free, with low smoke emission and no corrosive off-gassing during combustion. This makes them suitable for applications subject to RoHS, REACH, and other global environmental regulations.

FR5365 – Balanced Flow and Impact

With an MFI of 18 g/10min (260°C/2.16kg) and notched impact strength of 50 kJ/m², FR5365 strikes a practical balance between processability and toughness. One customer manufacturing large-format display bezels reported that switching to FR5365 improved fill in thin-wall sections and reduced scrap rates. The wider processing window also shortened their mold setup time.

FR5368 – Higher Heat and Chemical Resistance

FR5368 offers a heat deflection temperature of 88°C at 1.8MPa—5°C higher than FR5365—along with improved chemical resistance. For components that come into contact with cleaning agents, lubricants, or operate in elevated-temperature environments, FR5368 provides an extra margin of stability. Its MFI of 35 g/10min (260°C/5kg) ensures good flow for complex or long-flow-length parts.

Mechanical Balance

Tensile strength ranges from 60 to 62 MPa, flexural modulus from 2500 to 2600 MPa, and notched impact from 45 to 50 kJ/m². These are not extreme numbers—they are practical, reliable engineering properties that work for structural electronic housings, automotive interior components, and appliance parts.

Typical Applications

Display Bezel and Panel Frames

A home appliance manufacturer producing large-format display panels experienced short-shot issues in thin-wall sections with their previous flame retardant PC/ABS. Our technical team recommended FR5365. After trial molding, fill completeness improved, and the production yield stabilized. The customer also benefited from a shorter supply lead time compared to their previous overseas source.

Electrical and Electronic Components

Power adapter housings, relay bases, and circuit breaker enclosures all demand flame retardancy and dimensional stability. FR5365 handles most general-purpose E&E applications, while FR5368 is better suited for parts positioned near heat-generating components such as transformers or power semiconductors.

Automotive Interior Parts

Instrument panel trim, center console brackets, and HVAC outlet components require both flame retardancy and heat resistance. FR5368's 88°C HDT makes it a viable option for interior locations with moderate thermal exposure, such as near defroster vents or the upper dashboard area.

Technical Parameter Comparison

From the data above, the property profile of FR5365 falls within the same range as TAIRILOY AC3100, and FR5368 shows a similar trend to Bayblend FR3010 and CYCOLOY C2950. In practical terms, the applications where these well-known grades are used are well within the capability of FR5365 and FR5368.

What makes our grades different, however, is the flexibility we offer. Because we produce these materials in our own compounding plant, we can fine-tune the formulation for your specific requirements—whether that means adjusting color, improving low-temperature impact, or optimizing flow for a challenging mold geometry. We can run small-batch trials to validate the changes before full-scale production. This level of customization is rarely available with standard catalog grades from large international suppliers.

Supply Chain and Logistics

FR5365 and FR5368 are produced by Qingdao Primetech Plastics Co., Ltd., our own modification factory with over 16 years of compounding experience. The raw material supply is backed by Qingdao Prime Union Trade Co., Ltd., an authorized distributor of Chimei, SABIC, Hanwha Total, and Hyosung with more than 20 years in the engineering plastics industry.

We maintain in-stock inventory across six owned warehouses nationwide. Standard orders ship the same day. We support general trade, processing trade, and bonded warehouse operations—a flexibility that matters for customers operating under different trade regimes. For international customers, Qingdao Port provides direct access to major shipping routes, reducing transit times to key markets in Asia, Europe, and the Americas.

From production scheduling to warehousing to freight, we control the entire chain. This is why we can promise in-stock availability and rapid response when you need material on the production floor.
