Dual Laminates

Dual Laminates combine the best qualities of two (2) different plastic materials. Using a thermoplastic liner (PVC, CPVC, PP, PE, PVDF, E-CTFE/Halar®, ETFE/Tefzel®, MFA, FEP, or PFA) completely bonded to the FRP (Fiberglass Reinforced Plastic) structural reinforcement, thermoplastics are limited structurally as to pressure or vacuum service. Combining the corrosion resistant thermoplastic to the thermoset FRP structural reinforcement optimizes the properties of both the materials.

Piping, tanks, duct, scrubbers, dampers, columns and other process equipment can be fabricated using the dual laminate fabrication method.

Our supplier meets or exceeds industry standards in design and manufacturing of dual laminate. Those standards include ASME RTP-1; DVS 2205; DVS 2207; ASTM D-3299; ASTM C-1147; ASTM D-4163, and others.


		Polyvinyl Chloride (PVC) PVC has excellent chemical resistance to 140°f. Generally used in hoods, duct, small to medium sized process equipment. Plasticized PVC - Excellent chemical resistance, flexible, usually used in thinner linings. Temperature application range: to 140°f.


		Post Chlorinated Polyvinyl / Chloride (CPVC) CPVC, like PVC, has excellent chemical resistance but higher temperature stability up to 180°f. Plastek Werks is a certified Corzan CPVC fabricator, and has developed extrusion welding technology with regard to thicker plate fabrication.


		Polypropylene (PP) Polypropylene is used for plating, galvanizing, pickling, process, storage tanks, as well as tank linings, process piping, hoods, duct, machinery, conveyors and other items where corrosion is an issue. Available in both homopolymer and copolymer resins. Both copolymer and homopolymer polypropylenes have excellent chemical resistance. The homopolymers resin is a stiffer material and serves as a good structural material for self-supporting fabrications. The copolymer resin is more impact resistant with slightly less stiffness. Temperature application range up to 212°f (with limitations)


		Polyvinylidene Fluoride (Kynar®/PVDF) Kynar®/PVDF is a high purity, flame resistant material which meets FM 4910, and UL V-O. Excellent corrosion and chemical resistance. Temperature stability to 302°f. This polymer is made by Atofina. Temperature stability range: 40°f to 302°f.


		E-CTFE (Halar®) Halar®/E-CTFE (Ethylene – Chlorotrifluoroethylene) - High purity, flame resistance, low permeability. Extremely corrosion and chemical resistant. Mechanically tough and abrasion resistant. Temperature stability range: -105°f to 356°f.


		Ethylene-tetra Fluoroethylene (Tefzel®/ETFE) ETFE / Tefzel® - High purity, flame resistance, low permeability. extreme corrosion and chemical resistant. Mechanically tough and abrasion resistant. A fluoro-polymer with superior physical properties and chemical resistance approaching that of Teflon. ETFE is excellent where high pressure, vacuum, or cold flow is a problem. Temperature range is -20°f to 302°f. Tensile strength is approximately 6700 PSI. High purity, flame resistant. Extremely corrosive and chemical resistant.


		Fluorinated Ethylene Propylene (Teflon®/FEP) Teflon FEP (Fluorinated Ethylene Propylene) - High purity, high temperature stability. The most corrosion and chemical resistant material along with PFA & MFA.


		Perfluoroalkoxy (Teflon®/PFA) Teflon PFA ( Perfluoroalkoxy) High purity, high temperature stability. The most corrosion and chemical resistant along with FEP & MFA. The temperature application range: -310°f to 500°f.


		MFA MFA is a modified fluoroalkoxy similar to PFA. MFA is a copolymerization of tetrafluoroethylene and perfluoromethylvinylether. MFA is a new fluoropolymer for extrusion and eventually molding applications with an optimized price/performance ratio in comparison with other semicrystalline perfluoropolymers. MFA is designed for high temperature applications in the chemical industry. MFA has outstanding physical and chemical properties similar to those of other totally fluorinated polymers. It is similar to PFA. Temperature range is 475°F to 500°F.
