Cambridge Materials Testing
Plastics and
Composites
Plastics, polymers and mixed composites represent new developments in product technology and a challenge for manufacturers with the increased demands on product performance; uv testing as one example. Environmental impact, and most importantly potential health hazards to humans are the highest priority. CMTL routinely tests raw materials and finished products for harmful heavy metals contamination. Toy testing for harmful heavy metals includes lead testing, cadmium testing, cadmium analysis, BPA testing, silica analysis, antimony testing, arsenic analysis and barium are most in the news today. The industry continues to grow at a rate much faster than many others around the world. Plastics in some form have been used in every market in the world, construction, packaging, automobiles, boats, toys, electrical/electronics, consumer goods and more.

Product Development

CMTL works with its clients to aid in the development of standardized test methods including the construction of specialized fixturing that may be applicable to our client's specific needs. We have years of experience applying Physcial, mechanical testing, instrumental thermal analysis, spectrometric and microscopic characterization methods that benefit our client's product development. CMTL's staff of experienced professionals are specialists in heavy metals analysis.

Product Compliance

For many plastics, rubbers, and composites, the mechanical, physical and chemical properties are well documented in user specific standards. CMTL provides the necessary testing to satisfy automotive PPAP packages, CCMC and ICC building code requirements, as well the U.S Consumer Product Safety Commission (CPSC) requirements.

RoHS Compliance testing

CMTL performs RoHS testing; the aim of the RoHS directive is to restrict certain dangerous substances commonly used in electronic and electronic equipment. Any RoHS compliant component is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. RoHS regulations require that components must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component.
