General Information
| Item | Detail |
|---|---|
| Product name | CAM-205 Light Transmission Enhancing Masterbatch |
| Product type | Polypropylene clarifying / nucleating masterbatch |
| Carrier polymer | Polypropylene |
| Manufacturer | Zhejiang Bastone Technology Co., Ltd |
| Production site | Hangzhou, China |
| Process | Melt compounding and pelletisation of clarifier concentrate in PP carrier |
| Compliance | FDA and GB certified for hygiene and food-contact safety |
| Function | Increases transparency and surface gloss; raises rigidity and heat deflection temperature; shortens injection moulding cycle |
Technical Properties
| Property | Value | Notes |
|---|---|---|
| Transparency of finished part | Increased | Versus unmodified PP at equal wall thickness |
| Surface gloss | Increased | Versus unmodified PP |
| Rigidity | Increased | Result of finer spherulite structure |
| Heat deflection temperature | Increased | Result of higher crystallisation temperature |
| Injection moulding cycle time | Shortened | Faster part solidification |
| Hygiene certification | FDA, GB | Suitable for food-contact and daily-use plastics |
Numerical property values depend on the base PP grade, dosage level and part geometry. BASTONE runs dosage trials against a customer's own resin on request and reports measured haze, gloss and HDT results from the trial rather than publishing generic figures.
Recommended Processing Conditions
| Parameter | Recommendation |
|---|---|
| Addition rate | 1–5% (adjust to clarity target and base resin) |
| Melt processing temperature | Above 230 °C, to promote full dispersion of the nucleating agent |
| Cooling time | May be reduced relative to unmodified PP |
| Holding pressure time | May be reduced relative to unmodified PP |
The 230 °C floor matters more than the dosage. Nucleating agents only work when they dissolve into the melt and recrystallise as fine dispersed sites; running the barrel too cool leaves undissolved agglomerates that scatter light and undo the clarity gain. Moulders who report weak results with clarifiers are usually running short of temperature, not short of additive.
Applications
Polypropylene injection moulded parts. Housewares, storage containers, closures and thin-wall packaging all compete against PET and PS on shelf appearance. CAM-205 closes the optical gap while keeping PP's chemical resistance and lower density. The cycle time reduction is a direct production gain here: a thin-wall moulder running a two-second cooling reduction across a 24-cavity tool recovers meaningful annual output from the same press.
PP sheet and thermoformed products. Extruded sheet for blister packs, clamshells and trays needs clarity through a wall thickness that varies across the draw. Finer crystallisation gives more uniform optical behaviour through thick and thin sections. The higher heat deflection temperature also helps sheet hold shape during the reheat step of thermoforming and in end-use containers that see hot contents.
PP cast film. Cast film for packaging and lamination depends on gloss and low haze for print appearance and pack presentation. CAM-205 improves both without moving to a more expensive base resin, and the stiffness increase helps with film handling on downstream converting equipment.
Daily-use plastic products. Consumer goods — drinkware, food storage, bathroom and kitchen articles — need clarity plus hygiene documentation. FDA and GB compliance covers both Chinese domestic and export requirements, which simplifies certification for buyers selling into multiple markets from one production run.
Why Choose BASTONE
BASTONE manufactures CAM-205 in its own Hangzhou facility, not through a contract compounder. Every stage — carrier resin selection, active dosing, compounding, pelletising and batch testing — happens under BASTONE's own quality control. When a customer reports an off-spec result, BASTONE traces it back through its own production records rather than filing a claim with a third-party supplier and waiting.
The parent group is R&D-oriented, operating four production sites and one R&D centre. Formulation and testing capability sits inside the company, so BASTONE adjusts the masterbatch for a customer's specific PP grade, dosage window or optical target instead of offering a single fixed product. Trading houses reselling masterbatch cannot do that.
Buying direct from the manufacturer removes the intermediary margin that sits on most masterbatch imported from China. BASTONE quotes ex-works from Hangzhou and exports through Zhejiang Bastone Technology Co., Ltd, a platform with more than ten years of export experience. Trade terms, packaging format, port of loading and documentation all flex to the buyer's requirement, and BASTONE coordinates booking and shipping documents rather than handing the buyer off to a freight agent.
