Von Roll offers a comprehensive spectrum of composites materials available in different forms: flexible or rigid, in prepregs, sheets and long plates, tubes and cylinders and machined parts. Composites properties are optimized and consolidated by combining various substrates and resins in order to achieve the best results for use in the electro-technical and industrial applications or to replace other materials.
Von Roll produces a wide range of very flexible impregnated B-stage products for curing destined to different applications and available in various combinations.
Laminates are manufactured using low-pressure process using glass mat or chopped glass as a reinforcement material bonded with a polyester or epoxy resin system. Laminates are widely used in the electro-mechanical industries. Special qualities were also developed for the electronic industry and for thermal protection. Those products are attractive for their good mechanical and electrical properties, and their resistance against corrosion at high-temperature levels
They are known under following grades:
Laminates are produced using high-pressure techniques and are based on B-stage prepregs made from various reinforcements (glass, carbon, cotton, paper, aramid) and appropriate resin systems (epoxy, phenol, silicone). They are used in a wide field of industrial, electrical and thermal applications. Vetronite® and EGS product range combines glass cloth and various resin systems are suitable for a wide range of electrical, mechanical, and thermal insulating applications.
Von Roll is able to supply an extensive range of top-quality tubes and cylinders made from various reinforcement materials, such as glass fabric, glass mat, cotton, paper, aramid, polypropylene and HiPer-tex™. Materials are bonded with resin systems such as phenolic, silicone, polyester and epoxy. Depending on the grades, they can be supplied varnished or unvarnished in a very wide range of diameters and lengths, in standard sizes or made specially to customer specifications.
Based on various reinforcement materials and resin systems, U&L parts are high-performance machined components for use in rotors of large generators, in stators of large traction motors and windmills.
