Client Profile
A high-end domestic thermoforming manufacturer specializing in ultra-thin 0.5mm single-layer anti-static PS sheets for precision chip trays. They have strict requirements for resistance consistency and surface cleanliness.
Challenges
The previous masterbatch suffered from large batch-to-batch resistance fluctuation. Conductive / anti-static performance was inconsistent, leading to mass rejects and costly end-customer returns.
Our Solution
We developed a custom carbon-black dispersion system optimized for ultra-thin sheets. Tight controls on feeding, compounding and shearing minimize batch deviation. Free samples for trial production plus full on-site technical support to eliminate customer trial risks.
Trial Result
For 0.5mm ultra-thin single-layer thermoformed sheets: No streaks or specks on surface, uniform resistance across the full roll, fully compliant with ESD standards for precision electronics packaging.
Client feedback: "Your material stands out for its stability and reliability. It significantly lowered our reject rate and offers excellent cost performance."
Outcome
The customer established long-term, stable procurement and stopped frequent supplier switching.
