Perlast® FFKM O‑rings & seals Perfluoroelastomer (FFKM) is the most chemically resistant elastomer available and is effectively a rubber form of PTFE. FFKM O-rings and seals are used in critical sealing applications where purity, high temperatures, chemical resistance and retention of sealing force are paramount. Perlast® is the registered tradename of our FFKM elastomers, developed and exclusively molded by PPE, for the most challenging sealing environments.

Perlast Super-Six is a family of six perfluoroelastomer (FFKM) sealing material grades developed for the most critical industrial applications, providing: Extreme hot to cold temperature capability Excellent chemical resistance Outstanding mechanical properties FDA, USP Class VI, 3A 18-03 compliance Rapid Gas Decompression (RGD) performance These materials are offered with industry-leading technical support from specialist sealing engineers, to ensure enhanced performance and improved long term reliability.

Perlite, Al2CaFe2K2MgNa2O12Si, is a natural volcanic mineral which, after thermal treatment, resembles polystyrene balls in appearance, pumice in structure, and is chemically similar to glass.  Perlite ore is extracted from the deposit using the open pit method. After mining, the rock is crushed and ground into sand. The sand is then sorted into fractions, this is an important process because the size of a specific fraction determines what type of expanded perlite we will obtain in further processing. The perlite sand goes to expansion plants. There it is subjected to thermal treatment, which increases its volume. Perlite expands at temperatures over 900°C.  Then, chemically bound water molecules are released, which are a characteristic feature of this mineral. The escaping water causes the material to expand. As a result of this process, perlite increases its volume by up to twenty times. As a result, its density and bulk weight also decrease by twenty times, thanks to which we obtain a light and porous aggregate. Through our partner Perlipol we can offer a range of expanded, filtration and treated Perlites. We also offer expanded vermiculite for agriculture and animal husbandry.

PF containers are designed for the safe transport and storage of chemicals. They are suitable for acids, alkalis, corrosive liquids and food-grade substances.

Our scientists apply a range of PFAS analysis methods to identity and determine levels of PFAS in samples. Targeted PFAS analysis offers superior sensitivity and chemical specificity, enabling the precise quantification of the analytes at trace levels. However, this approach is inherently constrained by its scope, as it fails to account for unidentified and polymeric fluorinated compounds. To partially mitigate this limitation, the Total Oxidizable Precursor (TOP) assay is frequently integrated into analytical workflows. By utilizing an oxidation process, the TOP assay converts polyfluorinated precursors into measurable perfluorinated carboxylic acids (PFCAs), thereby providing a more representative estimate of the total PFAS environmental load in a sample. ISO 21675: - Water quality: Determination of per- and polyfluoroalkyl substances (PFAS) in water using solid phase extraction and LC MS/MS DIN 38414-14 - Determination of selected polyfluorinated compounds (PFC) in sludge, compost and soil DIN 38407-42 - Determination of selected polyfluorinated compounds (PFC) in water EN 17681-1 - Textiles and textile products - Per- and polyfluoroalkyl substances (PFAS) analysis of an alkaline extract DIN 3608 - Determination of perfluoroalkanoic acids by LC-MS/MS after oxidative digestion (TOP-Assay) Long chain PFAS chemical testing (C9-C21 LC-PFCAs) Custom semi-quantitative LC-MS/MS methods for selections of PFAS in multiple substances. Can be adapted to meet specific needs and sample types (examples include: hydrogen sector, electronics, personal care, polymers, foams). Non-targeted PFAS Analysis: This addresses the inherent limitations of (non-)targeted analyses, which fail to detect polymeric PFAS species.
