Plastic Shell Composition Analysis Test Report
I. Report Overview
The Plastic Shell Composition Analysis Test Report is a technical document that uses professional testing methods to qualitatively and quantitatively analyze the chemical composition, additive content, and hazardous substances of plastic shells. It is mainly used for quality control, product compliance verification, and R&D support.
II. Main Testing Items
| Category | Testing Items
| Composition Analysis | Identification of main polymer resin, type and content of fillers, plasticizer, and stabilizer content
| Physical Properties | Melt index, density, tensile strength, impact performance
| Hazardous Substances | RoHS restricted substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls/ethers), REACH substances of very high concern, phthalates, formaldehyde release
| Flame Retardant Properties | Flame retardant rating (UL94), burning rate
| Weather Resistance | Aging resistance, chemical resistance, and temperature resistance
III. Commonly Used Testing Methods
FTIR (Fourier Transform Infrared Spectroscopy): Identifies resin types
XRF (X-ray Fluorescence Spectroscopy): Screens for heavy metal elements
GC-MS (Gas Chromatography-Mass Spectrometry): Analyzes plasticizers and flame retardants
TGA (Thermogravimetric Analysis): Determines filler content and thermal stability
ICP-OES/MS (Inductively Coupled Plasma Optical Emission Spectrometry/Mass Spectrometry): Accurately determines heavy metal content
IV. Main Uses of the Report
1. Product Compliance: Proves that the product meets environmental regulations (e.g., for export to the EU market)
2. Quality Control: Verifies the batch stability of raw materials to prevent the use of inferior materials
3. Formulation Development: Helps companies optimize plastic formulations and reduce costs
4. Failure Analysis: Traces the cause when products exhibit embrittlement, cracking, or other problems
5. Procurement Basis: Assesses the quality of supplier materials
Recommendation: For official test reports, it is recommended to entrust a third-party testing institution with CMA/CNAS accreditation to complete the report. The report must bear the official testing seal to be legally valid. (Dezewei Testing CNAS Registration Number: L8083)
