Vipel® Chemical Resistance Guide Vipel® Chemical Resistance Guide CORROSION RESISTANT RESINS FOR THE HARSHEST ENVIRONMENTS The Right Chemistry for the Harshest Environments – AOC is leading the composites industry in the fight against damaging and costly corrosion. Our Vipel corrosion-resistant resins set the global standard for proven performance in a wide range of fibre-reinforced polymer (FRP) applications, including pipes, tanks, water and wastewater treatment, chemical processing, pulp and paper, mining and power generation. With unparalleled strength and durability, AOC resins combat corrosion in even the harshest conditions. 2 INTRODUCTION TO CORROSION RESISTANT RESINS Selecting a Resin System • Length of exposure to the medium if less than continuous.

  • General Properties of the Alkaline Phosphates: - Major Food and Technical Applications
    Phosphorus Research Bulletin Vol. 15 (2004) p. 85-94 General Properties of the Alkaline Phosphates: - Major Food and Technical Applications P.HOURANT Deputy Business Line Manager, Prayon S.A., Business Unit Phosphates, Rue Joseph Wauters, 144 4480 Engis, Belgium; E-mail: [email protected] INTRODUCTION The alkaline phosphates are used for many food and technical applications. Phosphates have two characteristics that explain their four main properties: buffer agent, sequestering power, dispersing power and water holding capability. Those properties allow phosphates to be used in many food and technical applications. The main food applications are meat and seafood processing, baking and processed cheese, but others such as cereals, French fries, fruits and vegetables, beverages, noodles and so on also may need the use of phosphates. On the technical side, the main applications are the detergent products, the water treatment and the metal treatment. As for the food, many other applications require phosphates such as ceramics, bone china, paper and paints,... In meat products, phosphates salts interact in a unique way to bind water with proteins and improve the tenderness in meats. Treated products will maintain their juicy appearance as well as their natural nutritional properties texture and colour. In fish and seafood products, phosphates salts allow the retention of the natural juices of frozen fish fillets, prawns, shrimps, scallops and other seafood. Phosphates also help prevent the build-up of struvite crystals in tinned tuna and crabmeat. In processed cheese, phosphates are crucially important in the production of processed cheese. These products ensure a homogeneous and uniform melt of raw cheese and product stability.

Received: 2 October 2020; Accepted: 17 November 2020; Published: 19 November 2020 Abstract: The effects of sodium hexametaphosphate (SHMP) addition on the dispersion and hydration of calcium aluminate cement were investigated, and the relevant mechanisms discussed. The content of SHMP and the adsorption capacity of SHMP on the surface of cement particles were estimated using plasma adsorption spectroscopy and the residual concentration method. The rheological behavior of hydrate, ζ-potential value of cement particles, phase transformation and the microstructure of the samples were determined by coaxial cylinder rheometer, zeta probe, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate that SHMP readily reacted with 2+ 2 Ca , forming complexes [Ca2(PO3)6] − ions which were subsequently adsorbed onto the surfaces of cement particles.

  • Chemical Resistance Guide Industrial Chemicals
    CHEMICAL RESISTANCE GUIDE INDUSTRIAL CHEMICALS The following pages are offered as a general guide and indication of the suitability of various elastomers and plastics in use today with a wide range of industrial chemicals. The ratings are based, for the most part, on published literature of various polymer suppliers and rubber manufacturers but, in some cases, they are considered the opinion of experienced compounders. We cannot guarantee their accuracy nor assume responsibility for use thereof. Several factors must always be considered in using a rubber or plastic part in service. The most important as we see them are: 1. The Temperature of Service: Higher temperatures increase the effect of chemicals on polymers. The increase varies with the polymer and the chemical. A compound quite stable at room temperature might fail miserably at elevated temperature. 2. Conditions of Service: A compound that swells badly might still function well as a static seal yet fail in any dynamic application. 3. The Grade of Polymer: Many types of polymers are available in different grades that vary greatly in chemical resistance. 4. The Compound Itself: Compounds designed with certain outstanding properties may be poorer in performance with a chemical than one designed especially for fluid resistance. 5. Caution: It is not recommended that PULSAtron®, CHEM-TECH or Mec-O-Matic pumps be used to handle flammable liquids. In light of the above factors, it is always best to test. 27101 Airport Road Punta Gorda, FL 3392 Phone: 941-575-3800 Fax: 941-575-4085 CHEMICAL
