The actual spectroscopic analysis is carried out by color reaction (e.g.

The CryoMill quickly grinds the preforms down to a powder of 100 microns and less which can then be used for extraction of the formaldehyde. In general, PET preforms can be grouped according to their opening size. Moreover, the sample is embrittled which improves the milling process. PET material is usually used to make preforms, and they are called PET preforms. The cooling ensures that the sample does not warm up during grinding, thus preserving the formaldehyde. The obtained granules are then pulverized in the RETSCH CryoMill at – 196 ☌ with liquid nitrogen. The first step, however, is the short and gentle preliminary grinding of the preforms in a cutting mill, such as RETSCH’s SM 100, with a bottom sieve of 6 mm. The concept of Backward Integration incepted by us, makes us the only beverage company in India to manufacture its own PET Preforms. To avoid this effect, cryogenic grinding is the method of choice. Along with producing thousands of different PET preforms aimed at meeting our customers. Because formaldehyde is a volatile substance, the mechanical energy input which is necessary for the grinding process can lead to its evaporation. EFI is a fully integrated one-stop-shop for all your preform needs. To do this reproducibly, the sample first has to be comminuted. Before the actual analysis can be done, the formaldehyde must be extracted from a sample. This is usually performed on the preforms for the beverage bottles. The beverage industry tests plastic bottles for formaldehyde as part of their quality control process. According to the German standard Oeko-Tex 100, baby clothes must not contain more than 20 PPM of this substance. It can cause allergic reactions and was classified as carcinogenic in 2004. However, formaldehyde is considered by many standards to be a health hazard. Formaldehyde is a chemical widely used in the industrial production of materials like plastics, for the processing of fabrics or to preserve biological materials.
