ETFE (ethylene tetrafluoroethylene) commonly referred to as Tefzel&is a modified copolymer of ethylene and tetrafluoroethylene. It has medium stiffness, which makes it suitable for applications such as chemical tank linings that require weldability and the ability to conform to curved metal or FRP surfaces. ETFE is often used in applications that demand mechanical toughness, moderate stiffness, and Why are grp.17 resins used for external surfaces?Why are grp.17 resins used for external surfaces?However, if the operating temperature is elevated above the resin design limit, eg due to a process upset, materials which are themselves innocuous may have adverse effects on GRP. 17 Resins used for the external surfaces of the unit should also be carefully selected to ensure that the satisfactory performance of the unit is not compromised.Glass reinforced plastic vessels and tanks

However, since the resistance of metals, plastics and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors.
Jan 24, 2019However, highly cross-linked isophthalic acid based polyester resin has been shown to be very resistant to this solvent blend and hence, suitable for the manufacture of underground petroleum storage tanks. Again, the correct choice of surface tissue and liner construction enhances the long term performance of GRP petroleum storage tanks.Fiberglass Tanks Plastic-MartIsophthalic resins have enhanced chemical resistance, tensile strength, durability, and fatigue resistance. Due to all the enhanced properties Nationwide Tank and Pipe use an Isophthalic Resin System in their standard engineered tank design to provide customers with a durable, long-lasting, maintenance free tank.

Tanks are constructed using either high density polyethylene (HDPE) or cross-link polyethylene (XLPE). Both of these resins offer different levels of chemical containment depending on their use.Double Wall Tanks Dual Wall Tanks Chemical DAY Tanks
The degree of stress on the plastic has a direct bearing on its resistance, therefore a tank and system should be designed to minimize stress. Tankdepot tanks are molded visually stress free, employing materials that are highly resistant to environmental stress cracking, and hence are less prone to cracking than fabricated tanks.Properties and Uses of Plastics as a Construction Material Chemical Resistance GRP Fabricated Tanks Properties of Plastics as A Construction MaterialUses of Plastics in Façade Panels, Exterior Covering, Carpentry etc.Uses of Plastics in Roof Coverings, Tightness, Domes and Lighting ElementsUses of Plastics in Sanitary Equipment and PipingOther Uses of Plastics in Buildings AppearanceChemical resistanceDimensional stabilityDuctility
