Heavy mass solid vinyl

Product definition

solid, filled, non-volatile mass

Remarks

The company Crown General is producer of articles (REACH Art. 3 No. 4). An article is defined as an “object which during production is given a special shape, surface or design which determines its function to a greater degree than does its chemical composition” (REACH Art. 3 No. 3). For articles or substances in an article no Material Safety Data Sheets (MSDS) need to be prepared (REACH Art. 31). With this Product Safety Information Crown General fulfils its information obligation according to REACH Art. 33. 2. Composition and data of the components Plasticised P.V.C. 3. Reach (SVHC) According to our current knowledge, our vinyl foam does not contain any ingredients which are harmful to human health/environment in a concentration of more than 0.1%. Concerning ADCA, this foaming agent has been included in the candidate list. A concentration above 0.1% gives us the obligation to provide enough information to allow the safe use. ADCA is a usual chemical foaming agent applied in foam production, PVC, PE, PP,…, because it decomposes thermally to more than 99.9% to generate gas (mainly nitrogen). Our production process complies with the generally recognised code of good practice whereby the temperature in our process is higher than the decomposition temperature of ADCA. Therefore we expect that our foams contain less than 0.1% of ADCA rest contents. However, any ADCA rest contents (traces) are embedded in the polymer matrix and will not be released under usual circumstances. The determination of ADCA rest contents is a very complex matter, in the current state of science no standard analytical method is available. 1
