Recommended Processing Conditions
| Parameter | Recommendation |
|---|---|
| Addition rate | 1–3% (adjust to actual requirement) |
| Processing temperature | Above 230 °C, to promote nucleating agent dispersion |
| Cooling time | Reduce as appropriate — CAM-3012 accelerates part solidification |
| Holding pressure time | Reduce as appropriate |
The 230 °C floor is not optional guidance. Clarifiers of this class must fully dissolve in the melt before recrystallizing as a nucleating network during cooling. Processing below the dissolution threshold leaves undispersed agglomerates that show up as haze streaks or gel specks, so a molder seeing inconsistent clarity should check barrel profile before questioning the masterbatch lot.
Applications
Polypropylene injection molded articles form the core application. Housewares, closures, storage containers, and thin-wall packaging all compete against PET, PS, and PVC on shelf appearance, and CAM-3012 closes the optical gap while the shortened cycle time offsets the material cost. The rigidity gain also lets some molders down-gauge wall sections without losing top-load performance.
PP sheet and thermoformed (blister) products benefit from the gloss and clarity improvement across a large visible surface, where haze is far more noticeable than in a small molded part. The higher heat deflection temperature widens the thermoforming window and helps parts hold shape during demolding and stacking.
Medical and laboratory ware — specimen containers, pipette components, sample vials, and disposable labware — depends on optical clarity so technicians can read fill levels and inspect contents. FDA and GB compliance is the entry requirement for the segment, and the HDT improvement supports articles that see steam or hot-fill exposure.
CD and disc cases need scratch-resistant gloss and consistent clarity across a flat, wide molded face. The stiffness increase helps hinged cases resist warp through repeated opening.
Household plastic goods cover the broad consumer segment where a glossy, transparent finish drives purchase decisions at the shelf. Cycle time reduction carries the most weight here, since household ware runs at high volume on thin margins.
Why Choose BASTONE
BASTONE manufactures CAM-3012 in-house at its own Hangzhou Economic Development Zone production facility, not through a contract compounder. Buyers deal with the party that owns the formulation, controls the raw material specification, and holds the batch records. When a lot question arises, BASTONE's plant traces it to the production run rather than routing the inquiry through a third party.
BASTONE operates as an R&D-oriented chemical group with 4 production sites and 1 R&D center. Formulation development, dispersion testing, and application trials happen inside the group, which means BASTONE can adjust addition rate recommendations against a customer's specific PP resin grade and molding equipment instead of pointing at a generic datasheet. Pure trading houses cannot offer the same technical depth.
Direct manufacturer pricing removes the distributor markup layer that sits between most overseas buyers and Chinese masterbatch production. Exports move through Zhejiang Bastone Technology Co., Ltd, BASTONE's export platform with over a decade of shipping experience, which handles trade terms, packaging configuration, container loading, and shipping documentation as one coordinated process.
Sourcing & Logistics
| Item | Detail |
|---|---|
| Supply origin | Manufactured at BASTONE's Hangzhou Economic Development Zone facility, China |
| Packaging | 25 kg bags, palletized; alternative configurations available on request |
| Export entity | Zhejiang Bastone Technology Co., Ltd |
| Documentation | COA per production batch, FDA and GB compliance statements, SDS, commercial invoice, packing list, certificate of origin, bill of lading |
| Trade terms | FOB, CIF, CFR — Ningbo or Shanghai port of loading |
| Sample availability | Trial samples available for molding qualification; contact BASTONE with target PP grade and application |
Buyers running a new qualification should send the base PP resin grade, target part geometry, and current cycle time along with the sample request. BASTONE's technical team returns an addition-rate recommendation with the sample rather than leaving the trial matrix to the customer.
