Why Source from Qingdao Prime Union Trade Co., Ltd.?

In the evolving landscape of the plastics industry, supply chain stability and technical support are as crucial as the raw material itself. We provide a distinct advantage through our integrated model:

Tier-One Access: We secure directly from Kingfa and other top-tier producers like Chi Mei and Double Elephant, ensuring competitive pricing and authentic, traceable materials.
Technical Backed by a Modifier: Our sister company, Qingdao Primetech Plastics Co., Ltd. , operates a 20,000㎡ facility with 22 production lines. This means if the standard KF-730 or KF-740 doesn't perfectly fit your need for a specific UL94 V-0 requirement or a custom color, we can modify it in-house. We bridge the gap between standard grades and your specific application demands.
Logistical Efficiency: With warehouses strategically located, we ensure just-in-time delivery to keep your injection molding operations running smoothly.
