Certification reports for silicone raw materials are available (ROHS, Halogen, PAHS, REACH, FDA, LFGB, MSDS, USP, NSF, UL Yellow Card, etc.). The authoritative certification bodies are SGS, TUV, CE, etc., and domestic CTI and other institutions.
The following is a brief description of each report:
1. The ROHS report is an environmental report. It mainly tests six heavy metals: Pb, Cd, Hg, Cr(VI), PBBs, and PBDE PBDEs).
2. Halogen detection includes (F, Cl, Br, and I).
3. PAHs mainly detect PAHs. Polycyclic aromatic hydrocarbons (Polycyclic Aromatic Hydrocarbons PAHs) are volatile hydrocarbons produced when incomplete combustion of organic matter such as coal, petroleum, wood, tobacco, organic polymeric substances, etc. are important environmental and food contaminants have so far been found More than 200 kinds of PAHs, a considerable part of which have carcinogenicity, such as benzo alpha alpha, benzo alpha alpha. PAHs are widely distributed in the environment and can be found in every corner of our lives. Polycyclic aromatic hydrocarbons may be produced in any place where organic matter is processed, discarded, burned, or used.
4. REACH is not the same as the RoHS directive. REACH involves a much wider range. It now adds 168 tests, which is the abbreviation of the EU Regulation “Regulation concerning the Registration, Evaluation, Authorization and Restriction of Chemicals”. It was established by the European Union and was completed on June 1, 2007. The regulatory system for chemicals to be implemented from day one. In fact, it will affect products and manufacturing processes from the mining industry to almost all industries such as textile and clothing, light industry, and electromechanics. This is a regulatory proposal involving the safety of chemicals production, trade, and use. The regulations aim to protect human health and the environment. Safeguard, maintain and improve the competitiveness of the EU chemical industry, and develop innovative capabilities for non-toxic and harmless compounds, prevent market fragmentation, increase transparency in the use of chemicals, promote non-animal experiments, and pursue sustainable social development. REACH has established the idea that society should not introduce new materials, products or technologies if their potential harm is not known.
5. FDA/LFGB tests for non-food drugs are mainly tests for food contact materials, FDA is the United States food certification report, LFGB is EU food certification report, FDA/LFGB are two completely different standard.
6. The MSDS report refers to the chemical safety data sheet, also known as the material safety factor sheet, the chemical safety data sheet and the chemical safety data sheet.
7. USP certification report states medical grade report, United States Pharmacopoeia (USP) - Overview of the organization The United States Pharmacopoeia (USP) develops quality standards for prescription and over-the-counter medicines, food supplements and other health products, and cooperates with health agencies to help them achieve standard. Since the establishment of 185 years, these standards have been contributing to all parts of the world to ensure access to quality pharmaceutical services.
8. The National Sanitation Foundation (NSF) is an independent non-profit organization founded in 1944. NSF is an authoritative organization in the field of public health and safety, which is dedicated to standard setting, product testing and certification services in the fields of public health, safety and environmental protection.
9.UL yellow card refers to the flame retardant rating:
UL approved: (flame retardant grade)
94VO: The highest level
94V2/94V1: Almost no present, manufacturers rarely produce.
94HB: Lowest level, all silicone rubber can meet this standard.
