W13-A-005 — Virgin vs Recycled Carrier in Masterbatch
1. What decision is the buyer trying to make?
Whether to accept a masterbatch built on a recycled polymer carrier or to require a virgin carrier, given cost, regulatory and quality constraints.
2. Which variables actually matter?
- Regulatory scope (food contact, medical, toy — usually forces virgin)
- Colour target and colour stability batch-to-batch
- MFI window of the end product
- Contamination risk (black specks, gels, cross-contamination)
- Sustainability / recycled-content declaration on the finished product
- Cost per kg of finished part, not per kg of masterbatch
3. Which variables are commonly misunderstood?
- "Recycled = worse" is not universal. Well-controlled PCR carriers can be acceptable for non-critical applications.
- Colour drift from a recycled carrier is often the real cost, not the raw material price.
- Regulatory compliance is a hard gate — not a preference.
4. What additional information is required before deciding?
- End-use and regulatory scope
- Colour tolerance (ΔE) accepted
- MFI window
- Sustainability claims planned on the finished part
- Volume stability required batch-to-batch
5. What should be included in the RFQ?
- End-use + regulatory scope
- Carrier preference or restriction (virgin only / PCR accepted / declared PCR %)
- Colour tolerance target
- Volume and packaging
- Batch-to-batch consistency requirement
So what should the buyer investigate next?
Whether their regulatory scope allows a recycled carrier at all — and, if it does, whether the colour tolerance in production really matches what a recycled-carrier masterbatch can hold.
