Selecting the right PC/ABS alloy often comes down to three competing needs: flowability for thin-wall molding, adhesion for plating applications, or impact strength for rugged enclosures. Over the past decade, we have supplied engineering plastics to tool manufacturers, automotive tier 1s, and electronics producers. Many faced long lead times from overseas brands or struggled with inconsistent properties from local suppliers. HI5330 PC/ABS alloy addresses high-flow needs; HI5345 is formulated specifically for plating; HI5365 delivers high impact and heat resistance. All three are produced by our own modification facility, Qingdao Primetech Plastics, and backed by Qingdao Prime Union's two decades of supply chain experience as authorized distributors for Chimei, SABIC, Hanwha Total, and Hyosung.

Key Properties

HI5330 – High Flow (30% PC content)

Melt flow index of 30 g/10min – ideal for thin-wall (down to 1.0mm) and long flow length parts.
Impact strength 35 kJ/m² sufficient for handheld devices and consumer electronics.
HDT 88°C suitable for low-heat applications like router or adapter housings.
A customer manufacturing drone remote controllers switched from a European brand to HI5330 PC/ABS alloy and eliminated short shots without changing mold or process parameters.

HI5345 – Plating Grade (45% PC content, low shrinkage)

Designed specifically for galvanic plating (copper/nickel/chrome). The 45% PC content matches thermal expansion of metal layers, preventing blistering.
Shrinkage 0.4-0.6% ensures dimensional consistency for precision parts.
An automotive interior supplier producing gear shift bezels had adhesion failures with generic PC/ABS. After switching to HI5345, all plating tests passed.

HI5365 – High Impact & Heat Resistance (65% PC content)

Impact strength 65 kJ/m² – three times higher than standard ABS, suitable for power tool battery packs and outdoor equipment.
HDT 102°C allows use under hood or inside high-power electronics enclosures.
Elongation at break 80% provides ductility for snap-fits and cold-temperature resilience. One customer making ski helmet clips passed -30°C drop ball impact tests with HI5365 PC/ABS alloy.

Applications with Real Cases

1. Thin-Wall Electronic Housings – HI5330
A power adapter manufacturer required filling a 1.0mm wall thickness design. Their previous material caused weld lines and short shots. We supplied HI5330, and the first trial run achieved complete filling with cycle time reduced by 8%. The customer now purchases 2-3 tons monthly.

2. Automotive Interior Plated Parts – HI5345
A tier 1 supplier for a Chinese joint venture brand needed plated PC/ABS for shift lever panels. After testing several options, HI5345 delivered the required adhesion and appearance. The parts passed all customer validation tests.

3. Outdoor Power Tool Battery Enclosures – HI5365
Specification required -20°C drop test and 60°C heat aging without deformation. HI5365 passed both. The customer reported a cost reduction compared to the imported PC/ABS they previously used.

Why PC Content Matters

In our experience, many engineers focus only on the data sheet values. But PC content directly affects long-term performance. After 1000 hours of damp heat aging (85°C/85%RH), HI5365 (65% PC) retains >80% of its impact strength, while HI5330 (30% PC) retains about 60%. For applications exposed to oils or chemical cleaners, higher PC content also improves chemical resistance. We offer sample plaques of all three grades for your own validation testing.

Frequently Asked Questions

Q: What is the typical lead time for samples?
A: Sample orders (5-10kg) ship within 24 hours from our Qingdao warehouse. Shipping cost applies; sample fee is refundable upon bulk order.

Q: What is the minimum order quantity (MOQ)?
A: Standard MOQ is 1 ton per grade. For trial runs, we can accept 500kg. In-stock items ship the same day.

Q: Do you provide on-site technical support for trial molding?
A: Yes. For domestic customers, our application engineers can visit your facility to assist with mold trials, process parameter adjustment, and defect analysis. For international customers, we offer remote support via video conferencing (Zoom, Teams) to review molding conditions and troubleshoot issues.

A: We are not just a distributor – we have our own modification plant (Qingdao Primetech). Our engineers understand the formulation and can quickly diagnose flow, warpage, or impact issues. We have successfully supported over 200 customers in tooling optimization and process fine-tuning.

Q: How does HI5365 compare to Covestro T65XF?
A: Both grades have a melt flow index around 30 g/10min and similar shrinkage (0.5-0.7%). Impact strength and HDT are also closely matched.

Q: Do you support bonded warehouse shipments for international customers?
A: Yes. We operate a bonded warehouse in Qingdao Free Trade Zone. We can ship to your bonded facility in China or directly export. No import VAT is required for re-export consignments.

Q: Can you provide a technical data sheet (TDS) for each grade?
A: Yes. TDS is available for HI5330, HI5345, and HI5365. Contact us to request the latest documents.

Q: How do I choose between HI5330, HI5345, and HI5365?
A: Use HI5330 for thin-wall or long-flow parts where moldability is priority. Use HI5345 for any component that requires electroplating. Use HI5365 when the part must survive high impact, low temperature, or sustained heat (up to 100°C).

Conclusion

Choose HI5330 for high flow, HI5345 for plating-grade performance, or HI5365 for high impact and heat resistance – all available in-stock from four China warehouses, with global shipping and bonded trade support.
